Astronauts and their rather unhelpful robot companion land on Venus only to stumble upon a group of scantily clad women who worship a pterosaur as God, and aren’t too fond of the Astronauts for killing their God. It’s the 1968 Mamie Van Doren-starring sci-fi flick directed by Peter Bogdanovich, Voyage to the Planet of Prehistoric Women, gloriously riffed on by Mystery Science Theater 3000's Trace Beaulieu & Frank Conniff.
