An imaginative boy (Tom Taylor) is transported to a fantasy realm, where he gets caught up in an epic battle between a noble gunslinger named Roland Deschain (Idris Elba) and a villainous figure known as the Man in Black (Matthew McConaughey). Later, Roland's quest to defend a magical tower from the Man in Black leads him to follow the boy back to Earth. Directed by Nikolaj Arcel (A Royal Affair), The Dark Tower was adapted from Stephen King's hugely popular series of fantasy novels.
