It looks like Christopher Nolan will be stepping away from the science fiction genre and setting his eyes on a war film.

According to Variety, the director announced that his next film will take place during World War II and revolve around Dunkirk. The film, currently titled "Dunkirk," was written by Nolan and will likely tell the story of the historical evacuation of the northern French city during WWII.

This is a change of pace for a director who has been acclaimed for working in the Science Fiction realm and also working on genre pictures. Nolan has never directed a war film so it will be interesting to see what he brings to the table.

The last time a film depicted Dunkirk was in Joe Wright's "Atonement," which was nominated for numerous Academy Awards, including best picture, and won best score.

The film will be released via Warner Bros. as the studio and the director continue their partnership after five consecutive films. Casting has not been confirmed but it is rumored that Mark Rylance, Kenneth Branagh and Tom Hardy are in talks for the film. The movie will be produced by Emma Thomas and is expected to be shot on 65 mm film and IMAX cameras, continuing Nolan's campaign to use film. There is no word on whether or not Nolan's regular cinematographer Wally Pfister will shoot the film.

Nolan is one of the most popular directors of today as he has produced and directed number of popular films including "The Dark Knight" series and "The Prestige." He also directed the Oscar-winning film "Inception" and 'Interstellar" and also produced "Man of Steel." Nolan broke into the industry with "Memento" for which he was nominated for the Academy Award. His first film was "Following" which he directed on a shoestring budget.

Warner Bros. has dated the film for July 21, 2017.
