After spending some time in the world of Batman, dreams, and space, Christopher Nolan is returning with what appears to be a good old-fashioned WWII picture: Dunkirk. The first trailer for the film shows a straightforward—though, admittedly, visually stunning—take on the evacuation of trapped Allied forces from that titular French locale while under German attack in 1940.
Nolan, naturally, has assembled an impressive group of actors that includes recent Oscar winner Mark Rylance, Tom Hardy, Cillian Murphy, and Kenneth Branagh. Still, the performer most of note to some is definitely former One Direction member Harry Styles, making his film debut. Styles doesn’t say anything in the footage released, but he is indeed heavily featured. Is casting a pop idol a little distracting when trying to make an epic war film? Sure. Will a bunch of people be curious to see how he does? Likely. Dunkirk—which doesn’t exactly look like light summer fare, but whatever—is headed to theaters July 21, 2017.
