The Santa Clause movie

Divorcee Scott Calvin is disgusted to learn that his ex and her husband have tried - and failed - to break it easy to their 6-year-old son Charlie that Santa isnt real. On Christmas Eve, Scott reads The Night Before Christmas... then receives an unexpected visitor on his roof. When hes startled by Scotts calling out and falls, the Santa impersonator disappears, leaving only an 8-reindeer sleigh and a suit with instructions to put it on if hes involved in an accident. Scott does, and is transported around the town dropping gifts through chimneys until hes taken to the North Pole and informed by a group who claim theyre elves that he is now Santa. Charlie is proud of his dads new job, though Scotts convinced its a dream. Until his hair turns white, his beard refuses to stay shaved, he gains weight inexplicably, even for his sudden love of junk food... Now hes accepted it, theres just one problem: how to keep it secret from his disbelieving family?
