Earlier today, a teaser for Christopher Nolan’s next film, the war epic Dunkirk, got leaked online ahead of its official debut before Suicide Squad this Friday. Warner Bros. quickly scrubbed the shoddy footage from the Internet, and to take back the message they have now released the teaser online, and it manages to drum up a hell of a lot of anxiety in just one minute. This is a prestige picture from top to bottom, with Nolan at the helm and Mark Rylance, Tom Hardy and Kenneth Branagh all starring in the British period drama that centers around the military evacuation of Dunkirk, France in 1940. And even though we don’t see him in this clip, yes, Harry Styles will also be appearing in the film, which will arrive in theaters on July 21, 2017.
