This is a little- known gem which, if it was made 5 years earlier, would have been a classic of the genre. AIP sci fi films are usually risibly bad but this one is very good and they have done a fine job with a limited budget. The colour photography is sharp and beautiful. The performances are adequate, just avoiding going over the top. The effects, apart from the rocket which is probably too small to be realistic, are excellent and for the most part are physical rather than optical. The android having his head taken off and replaced without any cutting is fantastically well done and so is the android ripped apart by the mutants. The film also moves at a fair crack and has the odd plot turn that keeps the viewer on their toes.
Give it a go. You will not be disappointed.
