Super Soul Brother (1978)
Absolutely perfect for riffing. The lead is the same doofus from "The
Guy from Harlem", who can't control the volume of his voice. He plays "Wildman Steve", who gets super powers (if the special effects can convince you of it at least), and robs a jewelry store at the request of some guy he just met. His vocal control hasn't improved at all, if anything, its gotten worse, lol. Not to mention, the doctor behind the entire "super powers" is a little person with a huge sex drive, lol. And he talks like he came straight out of a nazi prison laboratory. Plenty of flubbed lines and terrible camera work.
Even the title had to be changed to "Super Soul Brother. This wasn't the original title. I won't say what it used to be in the description, but if you google the name, you'll find the original name pretty quick. THIS MOVIE WAS MADE FOR RIFFTRAX!
