Watch the first trailer for Sam Mendes’ 1917 film

Benedict Cumberbatch & Richard Madden star in Sam Mendes’ World War 1 epic film 1917. “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. “
