I'm having a Christmas party, which movies should i watch?

Elf would be good for both kids and adults. Mickey's Once Upon A Christmas is a favorite of mine, and I think will work well for kids and adults, too. And How the Grinch Stole Christmas (if we're talking about the old Seuss cartoon and not the Jim Carrey live-action film) is a clic. Those would be my three choices. Good luck!
