Christopher Nolan knows how to do a blockbuster epic right. And his forthcoming film Dunkirk looks no different. The movie centers around soldiers from Belgium, the British Empire, Canada, and France who have been cut off by the German invasion and while it hits theatres on July 21, the first trailer is here.

Dunkirk stars Harry Styles, Tom Hardy, Cillian Murphy, and Kenneth Branagh, while Hans Zimmer will score the film.
