Who doesn't love Christmas? Well these stars lived it 24-7 while making the movies that changed their lives. Tim Allen jumped from TV to movies when he slipped into a fat suit for "The Santa Clause." Macaulay Culkin became an instant star and faced family problems of his own with "Home Alone." And Chevy Chase proved the fourth time was the charm for him when he played Clark Griswold in "Christmas Vacation."
