Come Haunt with Me(1971)

A mix of supernatural tone, comedic banter and nudity with musical numbers, it takes a while before this story of two scholars being courted and haunted by both, fox spirits and malicious ghosts, gets started. Do the scholars side with the fox spirits, trying to achieve immortality or are they being bewitched by it? It leads to a wild ending with a battle between humans, fox spirits and ghosts that seems more like a Halloween costume showcase than anything else.
