1917 is a 2019 British war film directed and produced by Sam Mendes, who co-wrote the film with Krysty Wilson-Cairns. Partially inspired by stories told to Mendes by his paternal grandfather Alfred about his service during World War I, the film takes place after the German retreat to the Hindenburg Line during Operation Alberich, and follows two British soldiers, Will Schofield (George MacKay) and Tom Blake (Dean-Charles Chapman), in their mission to deliver an important message to call off a doomed offensive attack. Mark Strong, Andrew Scott, Richard Madden, Claire Duburcq, Colin Firth, and Benedict Cumberbatch also star in supporting roles.
The project was announced in June 2018, with MacKay and Chapman signing on in October and the rest of the cast joining the following March. Filming took place from April to June 2019 in the UK, with cinematographer Roger Deakins and editor Lee Smith using long takes to have the entire film appear as two continuous shots.
1917 premiered in the UK on 4 December 2019 and was released theatrically in the United States on 25 December by Universal Pictures and in the United Kingdom on 10 January 2020 by Entertainment One. The film was a critical and box office success, grossing $384.9 million worldwide. Among its accolades, it received ten nominations at the 92nd Academy Awards including Best Picture and Best Director, and three wins, for Best Cinematography, Best Visual Effects, and Best Sound Mixing.
