Irish stars Andrew Scott and Kerry Condon join Oscar winner Brendan Fraser in the new WWII film Pressure, billed as "a thrilling account of the three-day run-up to D-Day".
Teeing up what's ahead in cinemas this September, StudioCanal said: "In the 72 hours leading up to D-Day, all the pieces are in place except for one key element - the British weather.
"Britain's Chief Meteorological Officer, James Stagg (Andrew Scott), is called upon to deliver the most consequential forecast in history, locking him into a tense standoff with the entire Allied leadership.
"The wrong conditions could devastate the largest ever seaborne invasion, while any delay risks German intelligence catching on.
"With only his trusted aide, Captain Kay Summersby (Kerry Condon), to confide in, and haunted by a catastrophic D-Day rehearsal, the final decision rests with Supreme Allied Commander Dwight D Eisenhower (Brendan Fraser).
"With only hours to go, the fate of the war and the lives of millions hang in the balance."
The cast of Pressure also includes Damian Lewis as Field Marshall Bernard Montgomery and Chris Messina as Irving P Krick, "Dwight D Eisenhower's trusted wartime meteorologist".
Pressure is directed by Hotel Mumbai director Anthony Maras and co-written by Maras and actor and playwright David Haig.
Haig wrote the play upon which the film is based and also played James Stagg in the stage production.
Pressure will be released in cinemas on Wednesday, 9 September.
