At the height of the First World War, two young British soldiers, Schofield (Captain Fantastic’s George MacKay) and Blake (Game of Thrones’ Dean-Charles Chapman) are given a seemingly impossible mission. In a race against time, they must cross enemy territory and deliver a message that will stop a deadly attack on hundreds of soldiers— Blake’s own brother among them.

1917 is directed by Sam Mendes, who wrote the screenplay with Krysty Wilson-Cairns (Showtime’s Penny Dreadful). The film is produced by Mendes and Pippa Harris (Revolutionary Road, Away We Go) for their Neal Street Productions, Jayne-Ann Tenggren (associate producer, Spectre), Callum McDougall (executive producer, Mary Poppins Returns, Skyfall) and Brian Oliver (Rocketman, Black Swan).
