Harry Styles to star in 'Dunkirk'

One Direction singer Harry Styles and Fionn Whitehead will star in Christopher Nolan's World War II action-thriller “Dunkirk.”

They will join Tom Hardy, Mark Rylance and Kenneth Branagh in the film, which centers on the British military evacuation of the French city of Dunkirk in 1940. “Dunkirk” will mark their feature film debuts.

British actors Jack Lowden and Aneurin Barnard have also joined the cast of “Dunkirk.”

“Dunkirk” will be shot on a combination of Imax 65mm and 65mm large format film. Shooting will begin in May at many of the locations where the true-life events actually took place.

The film hits theaters on July 21, 2017.
