The Santa Clause

Rooftop clatter leads to merry adventure after Santa falls down on the job, and Scott Calvin's son Charlie convinces dad to try on the red suit. Eight reindeer pilot the pair to the North Pole, where they soon discover that by donning the famous suit, dad must now accept all of Santa's duties! Over the next year, a surprised, not-so-jolly Scott grows a Santa-sized tummy and beard, causing friends, family and business associates to wonder if he's lost his marbles. All except Charlie, who thinks his dad is perfectly suited for his new job! (official distributor synopsis)
