“Moon Zero Two” was the most expensive film ever produced by Hammer Studios and is one of the oddest they ever created: a psychedelic western set on the moon in 2021 complete with claim-jumping, gunfights, zero gravity bar fights, candy colored space suits and go-go dancers. SF fans will enjoy early appearances by James Olson (“The Andromeda Strain”) and Catherine Schell (“Space 1999”). Also Hammer alumnae Warren Mitchell as the chief villain, Adrienne Corri as a cop (loved her boots), Bernard Bresslaw as a heavy and, of course, Michael Ripper scarfing up distilled rocket fuel at the saloon. The special effects are not that bad. Great ’60s kitsch and fun if you don’t take it seriously, “Austin Powers” fans may dig it.
