This movie is included in Mill Creek's Sci-Fi Invasion 50-Movie Pack. First of all, the quality of Mill Creek's copy of this movie is very disappointing. The picture is fuzzy and the pan-and-scan framing is terrible. Often, the tops of character's heads are cut off at the top of the screen or you just see part of a face or a nose at the edge of the screen.
As for the movie itself, it starts off as sort of a cross between PLANET OF THE APES and DELIVERANCE, but quickly turns into a WESTWORLD rip-off. A group of people with amnesia end up in a western town where Jack Palance is the head honcho. Newcomers are forced to become slaves of the town's inhabitants for one year. After a year they gain their freedom. If they kill 20 people, they become "immortal." Meanwhile, scientists at a control center watch the action on video monitors.
Overall, this movie is pretty dull and unoriginal. Jack Palance is okay, but Keir Dullea and Samantha Eggar are pretty boring. I rate it a dismal 1.5 out of 5.WARNING: THIS CLIP CONTAINS SPOILERS!!!!!!!
