What was that moon movie where the astronauts went to the moon to discover women in a cave on the moon where they could breathe air there without suits. I believe it was an old B&W movie, probably from the 50s or 60s. The women/creatures used her thumb to put some sort of mark on the astronaut's arm. What was that movie?

Cat-Women of the Moon (1953) (http://www.imdb.com/title/tt0045609/)
