Tales From the Crypt: And All Through the House (1972)
I was thinking about
Dead of Night (1945) but decided against it seeing as only one story is set at Christmas during a children's party. I decided to go with
Tales From the Crypt instead. Whilst only one section of that Amicus anthology is set at Christmas it is by far the best part of the film.
Tales From the Crypt is a better film than some of the others i've listed but it comes in at number ten purely because only a portion of the film is set at Christmas.
