The first trailer for Kathryn Bigelow’s Detroit easily could be mistaken for depicting some sort of apocalyptic future America, with the military turned against its own country. But the film is a look back at the country’s real past: the civil unrest that descended on the city for five days during summer 1967 .

“It’s a war zone out there,” someone says during the fast-moving events of the newly titled movie.

The film reteams Bigelow with her Zero Dark Thirty screenwriter Mark Boal and stars John Boyega, Will Poulter, Algee Smith, Jacob Latimore, Jason Mitchell, Hannah Murray, Kaitlyn Dever, Jack Reynor, Ben O’Toole, Joseph David Jones, Ephraim Sykes, Leon Thomas III, Nathan Davis Jr., Peyton Alex Smith, Malcolm David Kelley, Gbenga Akinnabve, Chris Chalk, Jeremy Strong, Laz Alonzo, Austin Hebert, Miguel Pimentel, Kris David, with John Krasinski and Anthony Mackie.

Annapurna Pictures releases Detroit on August 4. Take a look at the trailer above.
