Dunkirk is a 2017 war film written, directed, and produced by Christopher Nolan that depicts the Dunkirk evacuation of World War II through the perspectives of the land, sea, and air. It is produced by Syncopy Inc. and distributed by Warner Bros. Its ensemble cast includes Fionn Whitehead, Tom Glynn-Carney, Jack Lowden, Harry Styles in his film debut, Aneurin Barnard, James D'Arcy, Barry Keoghan, Kenneth Branagh, Cillian Murphy, Mark Rylance and Tom Hardy.
Dunkirk portrays the evacuation with little dialogue, as Christopher Nolan sought instead to create suspense from cinematography and music. Filming began in May 2016 in Dunkirk and ended that September in Los Angeles, when post-production began. Cinematographer Hoyte van Hoytema shot the film on IMAX 65 mm and 65 mm large-format film stock. Dunkirk has extensive practical effects, and employed thousands of extras as well as historic boats from the evacuation, and period aeroplanes.
Distributed by Warner Bros., the film premiered on 13 July 2017 at Odeon Leicester Square in London, and was released in the United Kingdom and United States on 21 July. It is the highest-grossing World War II film, making $526 million worldwide. Dunkirk received praise for its screenplay, direction, musical score, sound effects, and cinematography; some critics called it Nolan's best work, and one of the greatest war films. The film received various accolades, including eight nominations at the 90th Academy Awards: Best Picture and Best Director (Nolan's first directing Oscar nomination); it went on to win for Best Sound Editing, Best Sound Mixing, and Best Film Editing.
