The Naked Ape
 

I am in search of a rare out of print 1973 movie called
The Naked Ape, Victoria Principle is in it.
Can anyone help?

is that the one with Desmond Morris in it as the sexy and available behavioural scientist?

i like when he talks about how bums look like boobs in certain circumstances...

Yes
 

Yes, he was in it...it was produced by playboy.

You can try this site:

Try e-mailing the guy who runs it and see if he has information on the movie. He has it listed as a "lost" movie but the site hasn't been updated in a while so you might get lucky.

Other than that there's always eBay, you can sign up for one of their notification services where they e-mail if it comes up on the auction block.

I've seen this movie mentioned before as an extremely hard movie to find. So you might not have much luck in the usual places. Best thing to do is hit a number of different movie forums and hope someone owns it and is willing to sell you a copy.
