Back in August, we reported that the first trailer for the highly-anticipated adaptation of Stephen King's The Dark Tower will debut at Entertainment Weekly's PopFest, which will take place October 29 and October 30 at The Reef in downtown Los Angeles. Today an early, unfinished version of that trailer has leaked online, and we have the full video below. We're not sure how long it will be until this video is taken down, so check it out now before it's too late.

The last we heard about this long-awaited project was last month, when producer Ron Howard teased that a TV series is still being developed. Originally, Ron Howard and his Imagine Entertainment partner Brian Grazer had set up this sprawling adaptation at Universal Pictures. The studio had green lit the movie trilogy, with NBC set to air two limited TV series between the films, to flesh out this immense world even more. The studio eventually dropped the project, and after several months, Sony Pictures picked it back up, teaming with Media Rights Capital to finance both the show and the TV series.

It was also recently confirmed that The Dark Tower is not exactly a straight-up adaptation. Director Nikolaj Arcel explained in July that this project is in fact a sequel, that will set up a new "cinematic origin story." Many fans speculated this was the case, after set photos surfaced showing Roland Deschain, a.k.a. The Gunslinger (Idris Elba) possessing the Horn of Eld, which he has at the very end of Stephen King's final novel. Idris Elba himself teased that his iconic character is somewhat "lost" when we first see him in this movie, and that he's lost his sense of purpose as a protector.

The Dark Tower cast also includes Matthew McConaughey as The Man in Black, Abbey Lee as Tirana, Tom Taylor as Jake Chambers, Jackie Earle Haley as Sayre, Michael Barbieri as Timmy and Katheryn Winnick in an unspecified role. This movie is said to be the first of a trilogy, although no release dates have been set for the future sequels, or the TV show that is in development. Hopefully we'll learn much more about this adaptation when the official trailer finally arrives later this month.

Akiva Goldsman and Jeff Pinkner wrote the screenplay adaptation for The Dark Tower director Nikolaj Arcel, but we don't know for sure if the writers and director are also shaping the TV series. The Dark Tower has been set for release on February 17, 2017, going up against Fist Fight and The Great Wall and A Cure for Wellness. Take a look at the leaked trailer below, and stay tuned for the official version.
