I think this will be an easy one. I hope.
Fairly recent movie, I believe. Guy’s car breaks down somewhere, and this weirdo wearing a coonskip hat helps him out… Drags him out to this place in the woods where he lives. There’s a bunch of other assorted odd characters. Coonskin has main characters car keys, but won’t give them to him. End of film, main character manages to get back home, and opens a box which Coonskin gave to him, which, of course, has his keys in it.
For some reason, the details are extremely fuzzy, but I remember it being very surreal. I’m thinking I might have been half asleep when I watched it, but the details just popped into my head just now, and I can’t for the life of me figure out what movie it was.
