after the success of star war and there be a boost in interest in sci fi movie . this be one of those cheap attempt to cash in quickly . a group of survivor from a spaceship land on a planet inhabit by stop motion dinosaur and where half of them be systematically kill off ( the people not the dinosaur ) . porn movie level act . cheap special effect and even for the time and although it look like a lot of effort be put into them . costume be pure 1970 and a be the hairstyle . ahh and the 70 . i expect a disco to break out at any minute . nothing to really recommend in this film .
