The D-Day landings of World War II are no stranger to cinema treatment, but this gripping drama’s focus is less on the actual bloody combat and more a study of a behind-closed-doors Anglo-American battle of wills.

Based in a country house in the English countryside, the US director of operations General Dwight "Ike" Eisenhower (Brendan Fraser) confers with other high-ranking officers and determines the invasion must take place on the 5 June, ie in three days' time, but not everyone is in agreement.

The lone voice of contradiction belongs to the RAF’s chief meteorological officer Group Captain James Stagg (Andrew Scott), a kind of military Michael Fish, who believes a pair of approaching storm fronts will doom Ike’s plan to failure.

Therefore, the film title’s meaning is twofold; the urgency with which Eisenhower demands the combined air, sea and land attacks take place on the chosen date, and the weather conditions that Stagg insists could result in large-scale loss of life.

Stagg’s reservations are rubbished by all around him, including Field Marshall "Monty" Montgomery (Damien Lewis) and Eisenhower’s own weather expert Captain Irving Crick (Chris Messina), still arrogantly dining out on his consultancy role during the making of Gone With The Wind in Hollywood five years previously.

Based on a 2014 stage play by English actor-writer David Haig, the film retains many of its theatrical roots, the tension provided mostly by the heated arguments between Eisenhower and Stagg, with the egotistical Crick never far from the mix.

Scott, as Stagg, is a sombre, insular figure, unafraid to challenge his superiors, while intermittently distracted by concerns closer to home - his heavily pregnant wife back in London, whom he is unable to contact due the level of secrecy surrounding D-Day.

It’s a beautifully balanced portrayal, with Scott the picture of stoicism as the pragmatic expert while struggling to contain the fears he has for his young family; he may not be a front soldier, but the actor palpably exudes a different kind of heroism.

He gets the lion’s share of the good lines, not least when passionately stating his case: "The wrath of nature is real," he impresses upon Eisenhower, "and if you ignore it countless men and countless boys…" before his voice trails off.

Scott is matched each step of the way by Fraser, whose bulk and steely expressions are tailor-made to fit Eisenhower’s medal-adorned uniform, the epitome of a charismatic military man used to everyone following his every command.

Yet, beneath the brash, tactically gifted general persona, Fraser skilfully brings the man’s humanity to the fore, especially in exchanges with his trusted aide Kay Summersby, a deft turn by Kerry Condon, tasked with being the calming influence on both Ike and Stagg.

On paper, it may look like fairly dry material played out far from the bombs and bullets of the conflict itself, but director and co-writer Anthony Maras effortlessly conveys a climate of jeopardy and the oppressiveness of making life-or-death decisions, even when it’s just men poring over historical weather charts or making phone calls to far-flung outposts monitoring the storms' progress.

Maras stays true to historical fact throughout, admirably resisting the temptation to make Scott’s character a more user-friendly leading man; Stagg, by all accounts, wasn’t well-liked by those he worked with, and he remains so here, choosing professional integrity over popularity.

If anything, the director heightens the human intensity of the original play, blessed by a cast (Fraser and Scott in particular) who bring remarkable nuance and depth to driven characters trying to make sense of, and find a clear path through, the fog of war.

Pressure is released in UK cinemas on Wednesday 9 September 2026.
