Christopher Nolan's next movie will be a WWII film

Christopher Nolan is stepping away from telling fictional stories for the first time in his career, instead choosing to focus his attention on the events of World War II.

According to Variety, Nolan's next project will be about the miracle of Dunkirk, where 195,000 British soldiers and 145,000 French and Belgium fighters were saved after being trapped by the Germans. The film will reportedly focus heavily on Operation Dynamo, looking at the ins and outs of how one of the most notable evacuations in history came to be.

Tom Hardy, Kenneth Branagh and Mark Rylance are all supposedly in talks to join the film, although there hasn't been any confirmation about any of their roles.

French newspaper La Voix Du Nord previously confirmed that this would be Nolan's next project after the current mayor of Dunkirk, Patrice Vergriete, announced that the city would host a "world-famous director" to shoot a movie about the events that took place 75 years ago.

Dunkirk will be shot on 65 mm large format and IMAX 65 mm film, meaning that the movie will probably be as visually stunning as Nolan's past films, including Inception and Interstellar, were.

Dunkirk is scheduled to hit theaters June 21, 2017.
