I Knew It Was About D-Day. I Did Not Know It Was About the Weather
I went into Pressure knowing roughly what sort of historical film I was getting. It was about the Second World War, specifically the days immediately before D-Day, so I expected military planning rooms, large maps on walls, men in uniform exchanging grave looks, and the familiar dramatic weight that comes whenever cinema returns to June 1944.
What I did not expect was quite so much weather.
Not weather as atmosphere, either. This is not simply a film where grey skies make everything look appropriately sombre. Weather is the central problem around which the entire story turns. Wind direction, cloud cover, tides, visibility, air pressure, conflicting forecasts and the deeply inconvenient fact that one of the largest military operations ever attempted was still vulnerable to something no general could command.
Anthony Maras’s film concentrates on the roughly 72 hours immediately preceding the Normandy landings, when Scottish meteorologist Group Captain James Stagg had to advise Supreme Allied Commander Dwight D. Eisenhower whether the invasion originally planned for 5 June 1944 should proceed. Andrew Scott plays Stagg, Brendan Fraser plays Eisenhower, Kerry Condon is Kay Summersby, Chris Messina plays American meteorologist Irving P. Krick, and Damian Lewis appears as Bernard Montgomery. The film is adapted from David Haig’s 2014 stage play, which already suggests why so much of the drama takes place indoors, around tables, telephones, weather charts and people becoming increasingly irritated with one another.
On paper, that sounds potentially very dry. It is basically a historical thriller about a forecast, and everybody watching already knows that D-Day happened on 6 June 1944. There is no mystery about whether the invasion eventually takes place, and no possibility of rewriting history to manufacture surprise.
Yet Pressure held my attention for its entire one hour and forty minutes, which I honestly was not expecting. It occasionally feels like the most stressful meteorological meeting ever held, but somehow that becomes its strength rather than its problem. By the time the decision is finally made, I had become invested in cloud formations and pressure systems in a way I cannot imagine anybody successfully pitching without the words “D-Day” attached.
And I actually liked it.
That may be the film’s first small victory.
A War Film Where the Enemy Is Mostly Somewhere Else
Pressure establishes early that making the wrong decision is not an abstract fear. The shadow hanging over Eisenhower is Exercise Tiger, the disastrous April 1944 rehearsal for the Normandy landings in which hundreds of Allied servicemen died after German attacks and failures of coordination. The film uses that tragedy to frame Eisenhower less as an immovable historical figure and more as a man painfully aware that a planning error can turn into rows of bodies.
That becomes important because the film has very little interest in giving us a conventional wartime antagonist. The Germans are obviously the military enemy, but dramatically they remain largely outside the room. The real conflict is between people who all want the same thing. Everyone wants the invasion to succeed. Everyone wants Allied casualties minimised. Nobody is secretly trying to sabotage the operation. The problem is that agreement on the objective does not produce agreement on what should actually be done.
That gives Pressure a peculiar kind of tension. The film is built from conflicting expertise rather than opposing morality. Stagg believes the weather is deteriorating badly enough to make the planned 5 June invasion potentially disastrous. Krick’s forecasting method gives him a more optimistic picture. Eisenhower needs somebody to be right, but neither meteorologist can offer the sort of certainty he would naturally prefer when tens of thousands of lives depend upon the answer.
The result is a war film built around uncertainty rather than combat. Phones ring. Reports arrive. Forecasts change. Weather charts are redrawn. Someone walks into the room with new information and suddenly yesterday’s confidence looks dangerous. The stakes are enormous, but the visual language remains largely bureaucratic.
I found that strangely effective. We know D-Day happened, but the people in these rooms do not know whether they are about to send an enormous invasion fleet into weather that could wreck the entire operation. History has already given us the answer. The film’s tension comes from temporarily returning us to the moment before anyone knew it.
Andrew Scott and the Difficulty of Being Right Without Being Likeable
Andrew Scott is very good as James Stagg, although the film initially seems determined to stop us warming to him.
Anyone carrying residual memories of his rather more charming work in Fleabag may need a moment to adjust. Stagg is not Hot Priest with a weather chart. He is prickly, formal, impatient and often conspicuously uninterested in whether anybody finds him pleasant company. He enters conversations already looking as if he would rather everyone else understood the obvious and stopped wasting his time.
Scott has spoken about being drawn to exactly that quality in Stagg. The man was not there to win affection. He had been placed inside an enormous military operation because somebody needed him to tell senior officers what he genuinely believed the weather would do, whether they liked the answer or not.
That makes him initially unlikeable but gradually compelling. Scott does not soften Stagg simply by revealing that he is secretly warm and cuddly underneath. The performance is more interesting than that. His rigidity comes from responsibility. The man understands that if he alters his scientific judgement because Eisenhower wants reassurance, the consequences will not be embarrassment in a meeting. Men will die.
The film gives him a domestic counterweight through his heavily pregnant wife Liz, played by Tamsin Topolski. Their separation during this crisis allows the screenplay to expose something beneath Stagg’s severe exterior, although this is also where the film occasionally feels the most obviously adapted from a stage drama. The personal danger surrounding Liz sometimes seems designed to make sure the meteorological pressure has an emotional twin elsewhere.
I did not dislike those scenes, but I was more interested in Stagg when his emotional problem remained inseparable from his professional one. He knows more than most of the people around him about the weather, but that does not mean he can promise what the weather will do. His expertise has led him not to certainty but to an educated awareness of uncertainty.
That is a difficult position to dramatise, because cinema usually prefers its experts to be geniuses who know the answer while everybody else refuses to listen. Stagg is more complicated. He is essentially telling Eisenhower, “I know enough to know this is dangerous, but I cannot guarantee what happens next.”
There is something quietly courageous in refusing to sound more certain than you are, especially when the entire room is begging you for confidence.
The Real Forecast Behind the Drama
The central historical situation is not something invented to give a talk-heavy screenplay dramatic stakes. D-Day really was originally planned for 5 June 1944, and James Stagg really was the chief meteorological adviser responsible for bringing together the different forecasts being produced for Allied command.
Those forecasts did not agree.
The British teams were working with developing synoptic forecasting techniques and knowledge of the volatile weather moving across the North Atlantic. Irving Krick and the American team favoured an analogue approach, comparing current conditions with past weather patterns and then projecting what would happen next. The method had proved useful in other climates but was much less dependable around Britain and the North Atlantic, where the weather has spent centuries developing a reputation for refusing to behave itself.
There were, of course, no weather satellites. Observations came from ships, aircraft and stations, with charts drawn and redrawn by hand as information moved through the forecasting network. Allied codebreaking also provided access to some German weather observations, giving the forecasters additional information about Atlantic systems.
All of this sounds primitive from the perspective of a modern weather app, but that is part of what makes the situation so interesting. The technology was limited, but the consequences attached to the forecast were almost absurdly large.
Stagg eventually warned Eisenhower that the conditions expected on 5 June were too dangerous, and the invasion was postponed. A narrow improvement then appeared likely for 6 June. It was not ideal weather, merely a window in which the operation might reasonably succeed.
That distinction matters. Stagg did not announce that the skies would clear and everything would be fine. He identified the least dangerous opportunity available.
The invasion went ahead.
The weather deteriorated again afterwards, and had Eisenhower delayed until the next suitable combination of tides and moon conditions, the invasion fleet could have encountered significantly worse Channel weather. The decision therefore acquired the retrospective appearance of extraordinary precision, though Pressure is at its best when it reminds us that the people involved experienced it as anything but certain.
From Stage Play to Command Room Thriller
David Haig first developed the story as a stage play, with Pressure premiering at the Royal Lyceum Theatre in Edinburgh in 2014. Haig himself originally played Stagg, and the production later moved to the West End. The film retains much of that theatrical DNA.
You can feel the stage beneath it.
Most of the important scenes involve people in rooms arguing. Someone enters with new information, relationships shift, somebody leaves angry, and another piece of information changes the situation again. This is not a criticism so much as a description of the film’s natural form.
Anthony Maras does not try too hard to disguise it. Instead he uses the contained locations to increase the sense of compression. The headquarters begins to feel like a sealed box in which everyone is breathing the same increasingly stale air while knowing that an unimaginable military machine is waiting outside for an answer.
That plays to the material better than expanding the film into a conventional war spectacle would have done.
The production also reportedly consulted meteorological specialists to make the weather forecasting processes convincing, and that attention to procedure gives the film texture. Information does not magically appear. Observations travel. Reports are interpreted. Charts change. People disagree about how much confidence to place in each model.
This is history as process rather than mythology.
I found myself enjoying the physical nature of it. Paper matters. Telephones matter. Pencils matter. A line drawn across a weather chart matters because everyone in the room understands what it might mean.
There is something almost analogue about the suspense. Information has to be received, processed, debated and physically carried between people. Nothing simply refreshes itself on a screen.
For someone who spends much of modern life looking at information that appears instantly and disappears just as quickly, that gives the film a strangely tactile quality.
Brendan Fraser as Eisenhower, and the Face I Could Not Quite Stop Seeing
Then there is Brendan Fraser.
I had already seen him in Rental Family, where I thought he was awesome in a dramatic role, so I was perfectly prepared to accept this later stage of Fraser’s career. He has moved well beyond the roles many of us first associated with him and has become increasingly interesting playing older men who carry visible emotional weight.
As Dwight D. Eisenhower, though, I struggled for a while.
The issue was not really the performance. It was the physical transformation and my own familiarity with Eisenhower’s face. There are certain historical figures who have become almost inseparable from a small number of archive photographs, and Eisenhower is one of them. The bald head, the forehead, the military uniform and that very particular mid-century American general appearance are already fixed in the visual memory.
Fraser is a much larger physical presence, and for a good portion of the film I could not quite stop seeing Brendan Fraser pretending to be Ike.
The makeup and thinning hair did not entirely solve that.
I also like Fraser, which perhaps made the problem worse. There is decades of screen memory attached to him, and an actor carrying that much familiarity sometimes has to work harder to disappear into somebody historical.
Eventually, however, I stopped worrying quite so much about whether he looked like Eisenhower because the performance began doing something more important. Fraser makes the burden of command tangible.
His Eisenhower is not presented as a statue who occasionally speaks. He is impatient, exhausted, capable of anger and deeply aware that everyone around him can provide information but nobody else can finally make the decision.
He wants certainty because certainty would spread the responsibility around.
Stagg cannot give him that.
That is where Fraser becomes most convincing. The performance is less about imitation than about the loneliness of leadership when every adviser can leave the room after giving an opinion but you are the one who has to say yes or no.
I never completely lost the awareness that I was watching Brendan Fraser as Eisenhower.
But by the final third, it mattered much less.
Stagg and Eisenhower: Expertise Meets Authority
The central relationship works because Stagg and Eisenhower are carrying two different kinds of responsibility.
Stagg must advise.
Eisenhower must decide.
Those jobs overlap, but they are not interchangeable.
Eisenhower can ask whether the invasion should proceed, but Stagg cannot make the military decision for him. Stagg can explain weather systems, pressure changes, wind speeds and likely cloud cover, but he cannot tell Eisenhower what level of casualties is acceptable.
Likewise, Eisenhower can command armies, ships and aircraft, but he cannot promote a cloud formation out of the way.
The film understandably heightens their clashes. The real Stagg had been working within Eisenhower’s command structure for months before these events, and their professional relationship seems to have been more established than the film’s compressed drama suggests.
I do not mind that very much.
The friction serves the central question: what happens when authority depends on expertise it cannot fully understand?
Eisenhower keeps pushing because his entire job is to turn uncertainty into action. Stagg keeps resisting because his job requires him to remain honest about what cannot be known.
Neither position is absurd.
That is why the argument holds.
If Eisenhower simply ignored science, he would become a fool. If Stagg possessed perfect information, he would become a prophet.
Instead the film gives us two competent men caught on opposite sides of the same uncertainty.
Irving Krick and the Appeal of Confidence
Chris Messina’s Irving P. Krick is essential because he offers something Stagg refuses to provide.
Confidence.
Krick believes his forecasting method is sound and expects the weather to be more favourable. Historically, the disagreement between the forecasting teams was real, and Krick had considerable professional standing. The film is careful not to present him as a cartoonishly arrogant American who exists merely to make the British forecasters look cleverer.
That would have made the argument much less interesting.
Krick believes his method.
More importantly, he gives senior commanders an answer they would naturally prefer to hear.
That is where Pressure becomes more relevant than a straightforward wartime reconstruction.
Expert disagreement is uncomfortable because most people, especially people who need to make immediate decisions, do not actually want competing probabilities. They want an answer.
The confident expert therefore has a natural advantage over the cautious one.
Stagg’s language is full of qualifications because weather forecasting requires them. Krick sounds more decisive because his model encourages him to be.
One of the film’s better ideas is that the person who sounds most convincing is not necessarily the person behaving most responsibly.
That feels rather contemporary.
We live surrounded by forecasts now. Weather models, financial projections, algorithms, polling, risk assessments, artificial intelligence predictions and endless claims that one system understands the future slightly better than another.
The technology has changed.
The human appetite for certainty has not.
Kerry Condon and the Human Temperature of the Room
Kerry Condon plays Kay Summersby, Eisenhower’s driver and secretary, and gives the film something it badly needs: somebody capable of reading the room without being trapped inside the argument.
Summersby becomes a bridge between Eisenhower and Stagg. She understands Eisenhower’s moods and recognises that Stagg’s difficult personality is not the same thing as indifference.
Historically, that particular closeness between Stagg and Summersby appears to have been amplified for the screenplay, but dramatically I can see why it exists.
Without her, the film risks becoming ninety minutes of stubborn men explaining pressure systems to one another.
Condon gives the story warmth without sentimentalising it.
She is especially effective towards the end, when confirmation begins arriving that the landings have succeeded. The obvious performance choice would be relief breaking into celebration, but the film understands that success on this scale remains inseparable from death.
Thousands of men are still being killed and wounded.
The invasion succeeding does not make it clean.
Condon lets that contradiction sit quietly in her face.
It is one of the film’s better choices.
Montgomery and the Machinery Waiting Outside
Damian Lewis as Bernard Montgomery and the wider collection of Allied commanders help remind us that weather is only one part of an immense logistical equation.
The invasion depended on tides, moonlight, visibility, naval conditions, airborne operations, landing schedules and the movement of enormous numbers of troops and equipment. Every branch of the operation wanted particular conditions, and perfect conditions for everyone simply did not exist.
This is where Pressure gets away from the comforting idea that history is made through perfect decisions.
Nobody finds the perfect date.
Nobody gets the perfect weather.
They identify something survivable and go.
That is more interesting than genius producing a flawless solution.
History often seems cleaner after it has happened. Dates become fixed. Decisions become inevitable. Maps acquire arrows that make movements look obvious.
Pressure spends most of its running time trying to return the mess to the map.
Rooms, Maps and the Physical Design of Decision
The film’s production design does a lot of quiet work.
Much of Pressure takes place inside command rooms filled with enormous maps, desks, telephones, folders, lamps, ashtrays and weather charts. The palette is restrained: military green, RAF blue, dark wood, grey skies and institutional interiors.
It would have been easy to make all of this picturesque in the usual historical-drama way.
Instead it mostly looks like a workplace.
That distinction matters.
The rooms need to feel used rather than preserved.
People move behind one another. Papers accumulate. Telephones interrupt conversations. One report supersedes another. The map is not decoration. It is the thing everybody keeps looking at because thousands of people are represented by lines, symbols and arrows.
Mentmore Towers in Buckinghamshire stood in for the real Southwick House, the Allied headquarters associated with the D-Day planning meetings. The substitution works because the film is less interested in exact architectural recreation than in creating a convincing sealed environment.
The visual contrast between interior order and exterior weather is especially effective. Inside, everything is classified, scheduled, numbered and pinned down.
Outside, the atmosphere remains completely indifferent.
That opposition is almost the whole film.
Men have built one of the most complicated military operations in history, but a low-pressure system can still ruin the timetable.
Music That Does Not Try to Invade Normandy by Itself
Volker Bertelmann’s score is fairly restrained, which is probably the right choice.
I did not come away humming a theme, but I am not sure Pressure needs one.
The film already carries an enormous amount of historical significance. It does not require music constantly informing us that D-Day is important.
Instead, the sound design often does more useful work. Telephones ring. People speak over one another. Aircraft and vehicles become distant reminders that the invasion force is already moving towards readiness. The rooms have their own rhythm.
Bertelmann tends to increase tension rather than announce emotion.
That suits a film where the drama is based on information slowly becoming unbearable.
A louder, more heroic score might have pushed the material towards a conventional war film that Pressure is deliberately avoiding.
When the Film Finally Reaches the War
Eventually Pressure has to confront the obvious problem: you cannot spend an entire film preparing for D-Day and then simply end with everyone saying good luck.
At the same time, Anthony Maras had no reason to compete directly with Saving Private Ryan. Steven Spielberg’s Omaha Beach sequence has occupied such an enormous place in cinematic memory that trying to produce another extended recreation would have shifted the film into entirely different territory.
Pressure instead uses archival imagery alongside recreated material to connect the planning rooms to the invasion itself.
That is enough.
The important transition is not from dialogue to spectacle but from abstraction to bodies.
For most of the film, soldiers exist as numbers.
Troops.
Divisions.
Aircraft.
Landing craft.
Then the invasion begins and those numbers become people.
That gives the earlier arguments a different texture. Weather data stops being weather data. A forecast becomes something men are physically running through.
I actually prefer that the film does not turn itself into a battle epic.
There are already many films about the beaches.
The reason Pressure is worth making is that it stays behind and asks what happened in the rooms before anybody reached them.
The Ending and the Strange Relief of Being Right Enough
The forecast improves enough for Eisenhower to commit to 6 June.
D-Day proceeds.
The landings establish the Allied foothold in Normandy that will eventually contribute to the liberation of Western Europe.
None of that is a spoiler in the conventional sense. We know where history goes.
The emotional ending of Pressure is therefore not victory so much as release from uncertainty.
For most of the film, nobody knows whether the correct decision has been made. Stagg believes the weather window will hold, but belief based on expertise is still not certainty. Eisenhower gives the order, and after that there is nothing more to debate.
They have to wait.
Reports eventually begin coming back.
The operation is succeeding.
The weather, while far from ideal, has been good enough.
That phrase probably describes the whole decision better than any grander one.
Good enough.
Stagg does not become a cinematic genius standing triumphantly beside his chart while everybody applauds. Scott plays the relief much more quietly. The weight simply begins to leave him.
Likewise, the film does not pretend that Allied success somehow neutralises the enormous human cost.
The decision was right.
People still died.
Both things can be true at once.
Where Pressure Pushes Too Hard
The film does have weaknesses, most of them connected to the need to keep tightening drama around a historical event whose outcome is already known.
The 72-hour structure compresses relationships and makes Stagg appear less established within Eisenhower’s operation than he really was. His arguments with Eisenhower are heightened. The closeness between Stagg and Summersby is substantially dramatised. The danger surrounding Liz Stagg occasionally feels like the screenplay becoming nervous that arguments over weather are not enough.
There is repetition too.
Stagg warns everyone.
Krick disagrees.
Eisenhower asks for a clearer answer.
Stagg insists there is no clear answer.
Another weather report arrives.
The cycle starts again.
I can easily imagine viewers finding this frustrating.
Yet the repetition gradually began working for me because weather forecasting itself is repetitive. A forecast is not handed down once. It changes as observations arrive.
The form of the film begins to resemble the process it is depicting.
New information does not necessarily solve the problem.
Sometimes it only changes the shape of the uncertainty.
That becomes the tension.
A War Film About How Much We Can Know
There is an obvious “dad movie” quality to Pressure.
World War II. Maps. Meteorology. Logistics. Serious men discussing tides. Large wooden tables covered in paperwork. Nobody opening a portal to another universe.
I can see the appeal.
But underneath that surface, the film is really about knowledge.
What counts as evidence?
How confident should an expert sound?
How does a leader choose between specialists who disagree?
When does caution become indecision?
When does confidence become recklessness?
And what does responsibility look like when the available information can never remove risk entirely?
Those questions keep Pressure from feeling like a historical curiosity.
The technology surrounding us has changed enormously since 1944, but the fundamental problem remains familiar. We still build models of the future and then argue about which one deserves trust.
We still reward confidence.
We still become irritated by uncertainty.
And somebody still has to make the decision.
The Weather Was the Story
I went into Pressure expecting D-Day and came out thinking about the forecast.
That is probably the clearest measure of what the film gets right.
Andrew Scott gives it the difficult centre it needs. His Stagg is irritable, severe and sometimes actively unpleasant, but the film gradually reveals that those qualities are tied to a refusal to tell powerful men what they want to hear simply because the truth is inconvenient.
Brendan Fraser took longer for me. I could not entirely stop seeing Fraser beneath Eisenhower’s thinning hair and uniform, particularly after enjoying him so much in Rental Family. But eventually the burden inside the performance became more important than the physical mismatch.
Kerry Condon brings a necessary human intelligence to the rooms. Chris Messina makes certainty seductive enough to be dangerous. Damian Lewis and the wider military cast keep reminding us that an enormous machine is waiting outside for somebody to give it permission to move.
And Anthony Maras somehow keeps all of this interesting for around 100 minutes.
That still surprises me.
There are more spectacular D-Day films, more emotionally devastating war films and certainly more visually expansive ones. Pressure finds its own reason to exist by concentrating on the small group of people who had to decide whether the weather was survivable before history could become history.
We already know what happened on 6 June 1944. What the film manages to recover is the uncomfortable period immediately before it, when the date had not yet hardened into history and the Channel was still just grey water beneath an uncertain sky.
For a film built around a weather forecast, that turns out to carry quite a lot of weight.
