We don't have many Thanksgiving films here where I am....
You know, they don't really have very many Thanksgiving films and shows at
all, come to think of it. I found a list at
Wikipedia--not familiar with half of these, honestly. The last Thanksgiving film I saw was a real turd a few years back called
Pilgrim--were they actors playing Pilgrims? were they the vengeful ghosts of Pilgrims? I was never quite clear. Talk about a turkey.

I think
The Simpsons,
King of the Hill, and
Family Guy have one or two Thanksgiving episodes apiece, and so did
The Cleveland Show, if you don't mind an epic thirty-second-long vomit scene. :'( Turkey Day is rather unappreciated, it seems. The only holiday less recognized is Groundhog Day. I mean, yeah, you've got at great Bill Murray movie and an old Casper The Friendly Ghost cartoon and... that's it.
