I was wondering if anyone had any suggestions for non-Horror movies that would still work as 'Halloween' movies? I was thinking about this recently, and I realised that the Wizard of Oz makes an awesome Halloween movie despite not being horror, and I bet there are others also work.
To more literally answer your question with non-horror films that feature Halloween directly, there's this: http://en.wikipedia.org/wiki/List_of_films_set_around_Halloween
Also Costume Quest, and TV specials like It's the Great Pumpkin, Charlie Brown.
Coraline and Paranorman are great more recent movies. While not featuring hallowing they both deal with horror themes without being scary, but more charming and cozy. Coraline gets a little creepy though, but it's really not that bad, it is still a childrens/family movie after all.
