Ok so there are lots of movies and sequels. But I'm looking for movies that started out as just a regular kind of movie that got a Christmas themed sequel.
National Lampoon's Christmas Vacation (1989)
Look Who's Talking Now (1993)
An All Dogs Christmas Carol (1998)
Beauty and the Beast: The Enchanted Christmas (1997)
A Dennis the Menace Christmas (2007)
A Madea Christmas (2013)
