Idris Elba and Matthew McConaughey star as the hero and villain, respectively, in this convoluted sci-fi action film, a continuation of an eight-book series by Stephen King. McConaughey plays a sorcerer in a parallel universe who’s trying to harvest children’s minds in order to power a laser beam that will destroy a high-rise that protects the universe from malevolent forces; Elba is the gunslinger who’s trying to stop him. The source material is famous for its combination of fantasy, horror, and westerns, but this adaptation tries to condense the anthology into an hour-and-a-half-long movie—the result is incomprehensible schlock. McConaughey, dressed like Siegfried and Roy, gives a campy performance that’s the only saving grace. Danish filmmaker Nikolaj Arcel (A Royal Affair) directed, and I’m not sure why. With Jackie Earle Haley.
