Christopher Nolan is headed to Dunkirk.

Warner Bros. announced Monday that principal photography has begun in Dunkirk, France, on Nolan’s upcoming World War II action thriller. Nolan wrote the script and is directing Dunkirk, which tells the story of the real-life 1940 evacuation of hundreds of thousands Allied soldiers, who found themselves caught between the ocean and an advancing German army.

The star-studded cast includes Tom Hardy, Mark Rylance, Kenneth Branagh, Cillian Murphy, and newcomer Fionn Whitehead in unspecified roles. Other ensemble cast members include Harry Styles, Aneurin Barnard, James D’Arcy, Jack Lowden, Barry Keoghan, and Tom Glynn-Carney.
