Prey (1978)

At risk of giving away the ending, Alien Prey (1978) makes the best case ever for ladies going off to enjoy lesbian love in their own private paradise. Glory Annen and Sally Faulkner are certainly enjoying themselves - showing full nudity - before spaceman Barry Stokes lands his ship nearby. Glory’s friendly enough to invite the enigmatic alien inside, mainly because she doesn’t know he’s using the body of a young man whom he’s already annihilated. The lesbians are soon dressing the alien in drag, but Glory also seems to like the visitor’s strictly male persona - to the point where a jealous Sally is soon running around with an axe. Sadly, the ladies both get eaten in the only way that we don’t want to see. And the real tragedy is that the alien then contacts his own planet and announces that he’s found an ideal race for breeding! That would never happen if the guy landed on Rosie O’Donnell’s property.
