If you like Allen, you'll enjoy this lightweight holiday comedy about divorced workaholic dad Scott Calvin and eight-year-old son Charlie (Lloyd). Seems Santa injures himself falling off the Calvin roof and dad winds up putting on Santa's suit. But as it turns out when you put on Santa's suit, you become Santa, including a noticeable weight gain, a fluffy beard, and all those reindeer and elves to deal with (but where's Mrs. Claus?).
