Stephen King's epic dark fantasy series (eight books, a few short stories and some comics) gets loosely adapted with this long-in-development flick that ended up in the lap of Danish director Nikolaj Arcel (Truth About Men, A Royal Affair). Idris Elba is a supernatural gunslinger locked in eternal battle with the Man in Black (Matthew McConaughey), trying to stop him from destroying the Dark Tower, a mystical object that holds all universes together. Or something like that. Basically all the books are mashed together here in an attempt to tell one quick story. Fans are likely to be disappointed.95 minutes PG-13.
