'Dunkirk' role was tough for Harry Styles

Former One Direction star Harry Styles says he found shooting Dunkirk physically tough.

The 23-year-old singer makes his acting debut in director Christopher Nolan's upcoming wartime saga and loved working on the ambitious film, reported RollingStone.

"The movie is so ambitious. Some of the stuff they're doing in this movie is insane. And it was hard, man, physically really tough, but I love acting.

"I love playing someone else. I'd sleep really well at night, then get up and continue drowning," Styles says.

Apart from the movie, Styles is also gearing up for the debut of his self-titled solo album set to release on May 12.
