i saw this film in the early 1980 a part of a triple feature at the local drive in ( so please if i error on the detail and my apology ) . at that time it be title night of the wolf or cry of the wolf or some such non relate drivel . it start with vampire attack on woman in the night ( in poor lighting ) . then it go to launch a rocket into space ( internal shot only ) . we wade through long dialogue over what the plot be about ( while walk around in a cardboard set ) . the ship land on a planet inhabit by vampire cave men ( all shot in black and white through a red filter ) . they find and rescue and and flee with the only non vampire cave gal ( which be never really explain ) . the crew escape back to earth without a solution to the problem ( luckily the red cloud dissipate free earth till the next time . ) the nightmare still linger in my head about this and truly the bad film that i ever saw .
