'The Dark Tower' Trailer: Idris Elba Kills With His Heart

Despite the concern of many, The Dark Tower—which is only three months away—has gone an uncomfortably long time without showing any footage to the public. Today's debut trailer should ease most Constant Readers' fears...and, we're guessing, rope in a herd of intrigued newbs.

Coming from Stephen King's eight-book series that hopscotches between genres, tones, dimensions, points of view and tons of his own novels, the Dark Tower movie seems to have distilled things into a palatable, understandable blockbuster franchise launch. The strongest evidence: In the source material, almost no specifics about the all-important, very-far-away Tower are clearly revealed until you're several books deep. In the movie, it's simplified and handed out from the start:

"The Tower protects both our worlds. If it falls, hell will be unleashed," Idris Elba's Roland Deschain, The Last Gunslinger tells Jake Chambers, a kid with the Shining. The Man in Black, who is worse than the devil, wants to destroy it.
