No, It's at Columbia
20 March 2004 | by ptb-8See all my reviews

Hilarious paper mache space serial from the last wobbly days of Columbia's serial production line, this provokes screaming gaping laughter from kids if they are lucky enough to see it. in fact you owe it to yourself and anyone you know to watch it episode by episode, night after night and attempt to follow what is going on. In the same demented league as FLYING DISC MAN FROM MARS or the near pornographic 1936 Republic masterpiece UNDERSEA KINGDOM, let me assure you we are NOT in Flash Gordon territory. ..well we are if PRC ever made serials, but they didn't so Columbia made a few as if they did. It looks sort of like the TV superman episodes, except there is a turnip looking space rocket that has sparkler/fizzer fireworks and a lot of visible wires. It goes to and from the Moon apparently, except all we really ever see is it arriving and leaving from the same brown paper cave. Fantastic!! Someone wants to do something to Earth...or something.
