This hilariously stupid film was edited together from three episodes of "Supa Jaiantsu," a Japanese TV show about an extraterrestrial superhero called Starman. (Funny, he doesn't look Jewish.) Balazar (sp?), the evil leader of the planet Zumeria (again, I'm guessing at the spelling) has been killed, but his brain was kept alive and plans to add the Earth to the Zumerian empire. He will do so by arming his soldiers with nuclear weapons and dispatching the mutants created by Zumerian scientists. In response, the high council of alien leaders (from their base on the Emerald Planet) orders Starman to Earth to stop the invasion and destroy Balazar's brain.
From there, we get a lot of strangely choreographed fight scenes that I swear have a "West Side Story" groove to them. These scenes show the Zumerians to be a bunch of wimps. All Starman has to do is kick a few butts, and the Zumerian soldiers flee for their lives. The mutants-- who I've nicknamed "The Radioactive-Steam Breather" and "Hawkwoman"--were so damned silly-looking, I laughed uproariously when they first appeared on-screen. And the high council looks as zany as any gathering of low-budget aliens you'll ever see.
Starman is a rather stodgy, uncharismatic superhero. If you played a drinking game based on how many times he changes facial expressions, you would die of thirst. Not to mention Starman's preposterous costume, which gives him a male camel toe that enters the room before he himself does.
When the Zumerians "disguise" themselves as Earth people (by dressing like Humphrey Bogart), we're told they paid for their food and clothes by robbing banks. Why they didn't just steal the food and clothing directly is anyone's guess. That's just one of many sub-plots the film introduces and just as quickly abandons. (Tommy Wiseau must have been taking notes.)
Still, this is a piece of entertainment made for Japanese children some 50-odd years ago. Its utter stupidity and silliness have endeared it to me. THE EVIL BRAIN FROM OUTER SPACE is 78 minutes of mindless fun that I likely will watch again someday.
