Harry Styles of One Direction arrives at the 2015 Billboard Music Awards at MGM Garden Arena on May 17, 2015 in Las Vegas, Nevada. 

In a casting move that can be described as boy band meets Battle of the Bulge, One Direction member Harry Styles will be joining the production of Christopher Nolan's WWII action thriller Dunkirk.

The Warner Bros. film centers on the British military evacuation of the French city of Dunkirk in 1940.  

Newcomer Fionn Whitehead has also be tapped to star in the project, which has already cast Tom Hardy, Mark Rylance and Kenneth Branagh.

Production on the film, which will be shot on 65mm large format film and Imax, will begin in May.

Dunkirk will be the Styles' feature film debut. Last summer, it was announced that One Direction would disband in 2016 and would not tour for their fifth studio album, so this casting may mark a career shift for the British recording artists, from the arena stage to the silver screen.

Styles is repped for management by Full Stop Management.

Dunkirk hits theaters July 21, 2017.
