Looking for name of movie from 70s or 80s

[H0wdyD3wdy]

20 years or so ago, I remember at my relative's house, seeing part of a movie that was something like this...

Some wanderers ended up in a village out in the woods in the middle of nowhere. There was something strange about the village, maybe something with the food? I don't remember.

Anyhow, they noticed caskets everywhere, or in use in weird ways, or something.

I don't remember much more, but I always wanted to see the whole movie. Does anyone have any ideas?
Thanks!
