I don't think I am crazy, but I remember a sci fi or fantasy movie. It was traveling either to the moon, mars or venus, and on this planet they ran into exotic women who ruled and men were the servants. The women ate metal and drank oil! There was rock creatures that would attack when you went outside in the bright sun and extreme heat and you had to travel in the shade so not to burn up. Does anybody know the name and is it available at all?
