Richard chats with "1917" co-writer Krysty Wilson-Cairns about tending bar, working with Sam Mendes and writing a film that is presented in one shot.

SYNOPSIS: 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.
