The Monster Club
1981 Vincent Price movie about a writer getting an invite to a club for monsters. Halloween favorite and it NEEDS riffing! https://www.imdb.com/title/tt0081178/
Michael Berger commented
This Amicus production is an anthology of three films and the third film is classic. The inhabitants of an isolated village say they get their clothing and food 'from boxes" which turn out to be coffins.
