Sci fi icon Robby the Robot followed his breakthrough role in Forbidden Planet with a comparative B picture which nonetheless gave him better billing. Despite its many amusing qualities, this one has pretty much slipped through the cracks and is seldom mentioned in the company of more famous A.I. pix like Colossus and 2001. But it's arguably the first of the computers vs. mankind movies. Although Robby's subsequent career has had its inevitable ups and downs (an unfortunate over-reliance on motor oil sidelined him for awhile), he's still a popular model for Japanese toys and has his own Wikipedia page.
