What happens when you let Christopher Nolan make a World War II drama? That’s more of a rhetorical question than anything, but just in case you need an answer, the first teaser for Dunkirk has arrived. Although brief, Nolan’s latest film looks every bit as gorgeous and intense as we imagined — maybe even more. As if we weren’t already tired of this disappointing summer movie season, Dunkirk just gives us another reason to think that 2017 can’t get here fast enough.

The first teaser trailer for Dunkirk is attached to Suicide Squad, and Warner Bros. probably wasn’t planning on releasing it online until tomorrow, but thanks to a leaked version that showed up on YouTube earlier today, the studio was forced to debut their official teaser a bit early.

Nolan’s new film reunites him with Tom Hardy (that looks like him walking toward the ocean in the trailer) and Cillian Murphy, and recounts the famous story of the daring World War II rescue mission:

“Dunkirk” opens as hundreds of thousands of British and Allied troops are surrounded by enemy forces. Trapped on the beach with their backs to the sea they face an impossible situation as the enemy closes in.

Dunkirk also stars Kenneth Branagh and Mark Rylance (steppin’ on Spielberg’s turf) and hits theaters on July 21, 2017.
