Every time I watch this movie, I like it more! It does so much on a small budget, with some great ideas~from sleep learning and a holographic clown for the children to the notion of survival of the fittest no matter what.
It's wonderful seeing John Cairney in a major role. I've had such a crush on him since I was about 12 and saw "Jason and the Argonauts" at the drive-in. Sadly, I didn't get to see him very often till TCM and other stations began airing his films.
The man who allowed himself to be "mechanized" as the ship's brain: That is so creepy to me. He's so calm and collected (as they say), when most would be shrieking, "What was I thinking?!" (rather like Mercy fully realizing what the Cybermen has done to her on "Doctor Who".)
