Every family has that one over-eager relative who means well but somehow triggers chaos with alarming accuracy. In the Claus household, that honour belongs to Arthur — the wide-eyed, big-hearted son of Santa. When one child’s present is accidentally left behind during the North Pole’s hyper-efficient Christmas delivery run, Arthur becomes determined to fix the mistake. What follows is a warm, spirited dash across the globe involving an ageing sleigh, a retired reindeer, and enough holiday mishaps to fill several Christmas albums. At its core, the film is a celebration of kindness, family, and the belief that no child should be forgotten. It’s festive, funny, and charming in a way that sneaks up on you.
