Although King's name is an obvious selling point -- his spotty page-to-screen track record notwithstanding -- the film's underlying tone and template owe debts to another Steven, Spielberg. From its adolescent hero discovering his greater purpose to the drawings that channel images deeply embedded in his consciousness, themes present in "E.T." and "Close Encounters of the Third Kind" initially come to mind.
Of course, part of that has to do with the myriad sources that King drew upon in establishing this universe, which has been awkwardly condensed to fit into a 95-minute movie. The result is a film whose plot is sheer simplicity -- young boy teams with grizzled man-of-few-words to save the world -- while allowing the details to basically just spill out in between fight scenes.
Tom Taylor plays young Jake, whose disturbing visions have his widowed mom ("Vikings'" Katheryn Winnick) at her wits end. In fact, she's about to commit the lad to an asylum when Jake receives a tangible clue that his intricately sketched dreams are real, stumbling through a portal into Mid-World, an imperiled alternate universe that threatens our own. "What happens in one world echoes in others," Jake is told.
There, he meets Roland (Idris Elba), the last surviving gunslinger. A brooding knight, he has sworn vengeance against Walter (Matthew McConaughey), an evil sorcerer determined to bring down the Dark Tower, thus letting demons escape and wreak havoc on their domain.
Roland, naturally, is reluctant about toting a kid around, grudgingly realizing -- as Walter does -- that Jake's psychic "shine" might augur greater importance.
Directed by Danish filmmaker Nikolaj Arcel, who's also one of four credited writers, "Dark Tower" sure feels like a work by committee. Its saving graces include casting the able Elba in a heroic role leavened by comedic fish-out-of-water moments, such as encountering Earth's great wonders, like sugary soda.
Tipping the scales toward the negative, meanwhile, are the clunky dialogue; a narrative that approximates a British tea-time show, only with bigger stars and a more expansive budget; and McConaughey. While the actor enjoyed a career renaissance with "True Detective" and "Dallas Buyers Club," tasked with playing a magically powered villain dashing off one-liners, to quote Dirty Harry, a man's got to know his limitations.
As noted, Hollywood has only sporadically mastered the art of conjuring movies and TV from King's work, and this is a busy year for such efforts, including Spike's series "The Mist" and the upcoming, eagerly anticipated movie version of "It."
"The Dark Tower" avoids the lowest rungs of that ladder. Taken on its terms it's hardly a disaster, delivering moments of fun on a basic level. But nor should anyone confuse this modestly scaled exercise with a towering accomplishment.
