Ciao maschio (1978)

This weirdo movie was a big hit at Cannes back in the late 70's. Bye Bye Monkey is an art film contemplation of gender roles, aging and history.

An immigrant man in New York (a very young Gerard Dépardieu) finds work at a historical wax museum and as a tech at a tiny art theatre house. He is seduced/attacked by the actresses there, one of whom he develops a more lasting relationship with. With more friends they find the carcass of King Kong on the beach and then adopt a baby chimpanzee. Things just get stranger and stranger as the story drifts into more and more surrealism.

I found very little about the film to be appealing and even less to be meaningful.
