A fresh look at the upcoming war drama "Pressure" has been released, with Irish stars Andrew Scott and Kerry Condon taking centre stage in the tense countdown to D-Day.

According to StudioCanal, the film unfolds during the critical 72 hours before the Normandy landings, when weather forecasts became crucial to the success or failure of the Allied invasion.

The newly unveiled clip offers a glimpse at the high-stakes historical thriller ahead of its cinema release this September, with Scott playing Britain’s Chief Meteorological Officer James Stagg and Condon starring as Captain Kay Summersby, aide to Supreme Allied Commander Dwight D Eisenhower.

The synopsis reads: "In the 72 hours leading up to D-Day, all the pieces are in place except for one key element – the British weather."

Scott’s character is tasked with delivering what the studio describes as "the most consequential forecast in history," while tensions rise among Allied commanders desperate to launch the operation.

The film description adds: "The wrong conditions could devastate the largest ever seaborne invasion, while any delay risks German intelligence catching on."

Condon’s character, Captain Kay Summersby, is portrayed as one of the few people Stagg can confide in as pressure mounts before the historic operation.

Academy Award winner Brendan Fraser stars as Eisenhower, with Damian Lewis appearing as Field Marshal Bernard Montgomery and Chris Messina playing wartime meteorologist Irving P. Kric.

The film is directed by Anthony Maras, best known for "Hotel Mumbai," and co-written with David Haig, who also wrote the original stage play on which the movie is based.

Haig previously portrayed James Stagg in the theatre production before the story was adapted for the big screen.

Pressure is scheduled to arrive in cinemas in Ireland on September 11, after the US release on May 29.
