After the success of Star Wars, there was a boost in interest in Sci-Fi movies. This was one of those cheap attempts to cash in quickly.

A group of survivors from a spaceship land on a planet inhabited by stop-motion dinosaurs, where half of them are systematically killed off (the people not the dinosaurs). Porn-movie level acting. Cheap special effects, even for the time, although it looks like a lot of effort was put into them.

Costumes were pure 1970's, as were the hairstyles. Ahh, the 70's. I expected a disco to break out at any minute.

Nothing to really recommend in this film.
