When it came to bullies and adolescence's other perils, misfit Brit schoolboy Alex Elliot (Louis Ashbourne Serkis) knew he couldn't count on the adults around him for much. So when revived Arthurian sorceress Morgan Le Fay (Rebecca Ferguson) and her minions threaten the world, it falls to him to wield Excalibur and rally his disbelieving classmates to his cause. Joe Cornish's throwback family adventure co-stars Tom Taylor, Angus Imrie, Rhianna Doris, Dean Chaumoo, and Patrick Stewart as Merlin. 120 min. Widescreen; Soundtrack: English.
