Teaser Trailer for Christopher Nolan's 'Dunkirk' Debuts

Tom Hardy, Mark Rylance and Kenneth Branagh star in the WWII movie.

The first official look at Christopher Nolan's highly anticipated WWII movie Dunkirk has arrived.

The Warner Bros. film centers on the British military evacuation of the French city of Dunkirk in 1940, one of the biggest battles during the war.

The minute-long teaser is a series of several wartime vignettes but features very few familiar faces from the A-list cast, which includes Tom Hardy, Mark Rylance and Kenneth Branagh, as well as One Direction alum Harry Styles. 

The official trailer is set to screen ahead of Suicide Squad, the studio's big superhero release that is out this weekend. Warner Bros. released the trailer on YouTube, following a pirated clip of nearly half of the teaser that surfaced online, which appeared to be taken on a mobile device from inside a movie theater.

Dunkirk, which is being shot on 65mm large format film and Imax, will hit theaters July 19, 2017.
