Plot: After Santa slips off his roof, Scott Calvin (Allen) – after some convincing by his son Charlie (Lloyd) – dons the red suit. Eight reindeer pilot the duo to the North Pole, where they soon discovers that by wearing the suit, Scott has accepted all of Santa’s duties. Over the course of the next year, a surprised Scott grows a Santa-sized tummy and beard, causing his friends, family and co-workers to think he’s lost his marbles – all that is, except Charlie, who thinks his Dad is perfect for the job!

Plot: Billy (Galligan) receives a strange little creature named Gizmo as an early Christmas present from his father. But, when Billy doesn’t follow the rules associated with his new pet, he inadvertently unleashes a horde of malevolent creatures on his small town.

Plot: It’s been 8 years since Scott Calvin (Allen) became Santa Claus, after the previous Santa fell off his roof. But, it seems there’s another clause that’s been overlooked: the Mrs. Clause. It turns out that Scott needs to get married by Christmas Eve, or he stops being Santa! His son, Charlie (Lloyd) is also getting into trouble at school with the principal, Carol (Mitchell). So, Curtis the elf (Breslin) comes up with a replacement for Santa while he goes to help his son: a life-sized Santa toy! Scott has 28 days and limited magic to find a wife, help out his son, and get back to the North Pole before the Santa toy wrecks Christmas!
