Dunkirk is a 2017 English-language war film written, co-produced and directed by Christopher Nolan. The film stars Fionn Whitehead, Tom Hardy, Tom Glynn-Carney, Jack Lowden, Harry Styles, Aneurin Barnard and James D'Arcy. The movie focusses on the evacuation of Allied soldiers from Belgium, the British Empire, Canada, and France, who were cut off and surrounded by the German army from the beaches and harbor of Dunkirk, France, between May 26- June 04, 1940, during the Battle of France in World War II.

The score is composed by multiple award winner Hans Zimmer. On 5 April 2017, Zimmer revealed that he was nearly finished with the score and that it would be complete by the start of his Hans Zimmer Live on Tour shows in May.

For the purpose of intensity, the script was written to accommodate the auditory illusion of a Shepard tone, which had previously been explored in Nolan's 2006 film The Prestige. This was coupled with the sound of a ticking clock, that of Nolan's own pocket watch, which he recorded and sent to Zimmer to be synthesized.

The collaborative careers of Christopher Nolan and Hans Zimmer have proven to be a success in the last decade, with examples such as Interstellar, The Dark Knight and Inception. This score turns out to be epic once again.
