The first trailer for The Dark Tower is here. The long-awaited adaptation of Stephen King's classic series of novels hits theatres in August, and the new video promises a mix of lavish fantasy and spectacular gunslinging action. Check it out below:

　　The movie stars Idris Elba as The Gunslinger, while Matthew McConaughey plays demonic sorcerer The Man in Black. It also features Tom Taylor as young protagonist Jake, plus Katheryn Winnick (Vikings), Jackie Earle Haley (Watchmen), Dennis Haysbert (24), and Abbey Lee (Mad Max: Fury Road). A poster was released in March--check it out here.

　　The Dark Tower was originally set to hit theaters in February, but the release date was subsequently moved back to the summer. At the time, it was reported that the ambitious post-production process meant that hitting a February release would have added millions to the budget, so Sony decided to delay the film instead.

　　There has also been talk of a Dark Tower TV show. In September, it was reported that an adaptation of 1997's Wizard and Glass, the fourth book in King's epic series, was being planned.

　　However, more recently, producer Ron Howard stated that while a show was in development, it was far from definite. "[There's] not a commitment on the television side," he told TV Guide last month. "But creatively, it could work very well, hand in hand with what we'd like the movies to be."

　　The Dark Tower hits theaters on August 4, 2017.
