Watch the New Dark Tower International Trailer

The Gunslinger (Idris Elba) continues his pursuit of the Man in Black (Matthew McConaughey) in the new international trailer for The Dark Tower.

It's the best trailer yet for the adaptation of Stephen King's beloved series of novels, although it has been reported that the film is also going to function as a sequel of sorts. The particulars of how the story takes from, and expands on, the books, are impossible to tell at this point.

The only thing that is very clear is that the Man in Black fled across the desert, and the Gunslinger followed.

Their war. Our world. See #DarkTowerMovie only at cinemas! There are other worlds than these. Stephen King's The Dark Tower, the ambitious and expansive story from one of the world's most celebrated authors, makes its launch to the big screen.

The Dark Tower premieres in U.S theaters on August 4.
