I Love It!
A long time ago on a TV set far, far away, I saw this late at night a couple of times. This and War of the Planets. I never got to see the other two films in the Gamma One series. I just caught it again on TCM, also late at night.
Watching it out of boredom, and just for funzies, Wild Wild Planet (or Criminals of the Galaxy, as the Italians titled it) looked as cheaply made as I knew it would, took itself a little too seriously, was somewhat nolstalgic, a bit shagedelic, but mostly weird. Cops and crooks in the future, basically, with gadgets and strange stuff thrown in, and a sinister plot leading straight to an evil super-mastermind worthy of the Golden Age comics.
I wish the Gamma One series got a boxed-set release on Blu-Ray, and hopefully with a CD of the music in all four flicks. That keyboard-driven music would make some exotic lounge music. Some of it still sounds weird, even by today's post-modern standards. It is desirable to have these scifi flicks remastered with better picture and sound, but it would not make them seem any better.
