The man in black fled across the desert and the gunslinger followed. After an epic wait — including will-they-or-won’t-they TV spinoff rumors and shifting release dates — the film adaptation of Stephen King’s The Dark Tower finally has a first trailer.

Yesterday we enjoyed the badass teasers for this trailer, and now we get to see weary gunslinger Idris Elba (and his Horn of Eld) go after Matthew McConaughey, who’s gone from chill college professor to the Man In Black for this western sci-fi fantasy hybrid, which also co-stars Katheryn Winnick, Abbey Lee, Tom Taylor, Fran Kranz (as Pimli Prentiss), and Jackie Earle Haley.

Here’s the newest synopsis:

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 last Gunslinger, Roland Deschain (Idris Elba), has been locked in an eternal battle with Walter O’Dim, also known as the Man in Black (Matthew McConaughey), determined to prevent him from toppling the Dark Tower, which holds the universe together. With the fate of the worlds at stake, good and evil will collide in the ultimate battle as only Roland can defend the Tower from the Man in Black.

Baby, you can dig your man on August 4th.
