Ghost in the Invisible Bikini(1966)

I was watching the trailer for Ghost in the Invisible Bikini(1966) at You Tube. It was a campy comedy starring Boris Karloff, Susan Hart, and Nancy Sinatra and it was jam packed with bikini-clad women. Fred Olen Ray(alias Nicholas Medina) ripped this movie off, big time...or he made a movie with the same concept.
