1917 is a 2019 British war film directed, co-written, and produced by Sam Mendes. The film stars George MacKay and Dean-Charles Chapman, with Mark Strong, Andrew Scott, Richard Madden, Claire Duburcq, Colin Firth and Benedict Cumberbatch in supporting roles. It is based in part on an account told to Mendes by his paternal grandfather, Alfred Mendes, and tells the story of two young British soldiers during the First World War who are ordered to deliver a message calling off an attack doomed to fail soon after the German retreat to the Hindenburg Line during Operation Alberich. This message is especially important to one of the soldiers, as his brother is due to take part in the attack.
The project was officially announced in June 2018, with MacKay and Chapman signing on in October and the rest of the cast 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 received widespread critical praise and was a box office success, grossing $368 million worldwide. It received numerous accolades, including ten nominations at the 92nd Academy Awards and three wins, for Best Cinematography, Best Visual Effects, and Best Sound Mixing. It was the last film to win the Academy Award for Best Sound Mixing before the category was combined with Best Sound Editing as a single award for Best Sound. The film also won Best Picture at the 77th Golden Globe Awards, 73rd BAFTA Film Awards, and PGA Awards, while Mendes won Best Director at the Golden Globes, BAFTAs, and DGA Awards.
