They've come from beyond the stars to steal our women!  By sending bubble-headed goons and a Godzilla-type thing.

There's plenty of missiles, ray guns, floods and mayhem on show in this Japanese sci-fi flick.  Which is how it should be, of course.  I'm not sure if having the word "Mysterians" shouted by a different voice-over bloke was entirely necessary though.

Pointless Trivia!  This movie's original Japanese title is Chikyû Bôeigun (Lit. Earth Defence Force), the same name given to a series of video games based on a roughly similar premise.  But with added giant insects.  And early rock band Question Mark and the Mysterians were partially named after this movie.

Favourite bit:  "Mogera", the mole-faced giant robot that appears to be made out of corrugated boxes.
