When Merlin is betrayed by Morgana Le Fay, Balthazar Blake (Nicolas Cage) sets out on a quest across time to find his successor.
He emerges years later in the form of student Dave (Jay Baruchel) in present-day New York, and together they must defend the world from Morgana and her minions. If the story is lightweight and occasionally sentimental, the effects are top notch. And Cage holds the film together, even if Baruchel does grate as the 21st-century sorcerer. Will keep the young ones entertained.
