This is a bit of a classic film that I used to enjoy as a kid when it first made it's way on to British TV. Upon watching it again recently, very much as an adult now, it remained every bit as good as I remember.
It has in it three memorably fantastic robots and something of a bleak ending. It also has a very small and far away spacesuit sequence that is almost totally forgettable. These are the best images I can find.
If you've never seen this one then go track it down.
