Probably most horror geeks can relate to being obsessed with collecting. I’ve got more horror action figures than I care to admit at home. Of course mine are all sitting in a closet now... good luck with the marriage, Eric.
That said, the film “The Man Who Collected Food” is pretty far out there even by horror fan standards. The movie tells the story Miguel, a man who is obsessed with collecting... well food. These posts practically write themselves. But Miguel doesn’t just collect the food, he keeps it in perfect unopened condition in his cabinet.
