Yes, it's credited to Hammer, who gave us all those wonderfully poor horror movies made on a budget of three shillings tuppence happenny back in the 1960s. It's not meant to be Star Wars, and it isn't. But for its time (and we have to kind about such films) it's actually technically very accurate (no sound in space, etc.) and if you can ignore the kitsch design and costumes, it's actually quite good fun. I can imagine that the Moon of Moon Zero Two was a realistic and plausible view of human colonies on the Moon as seen from 1969, and why it might be a lot like the wild west. Every plot element of the film is lifted from cheap westerns, but it's a favourite of mine, perhaps because I was a child when I first saw it.
Just remember, it's actually more intelligent than many of the brainless (and plotless) movies which people seem to accept today without question!
