Robby was exploited for The Invisible Boy, MGM’s weak follow-up to Forbidden Planet, and teamed with Richard Eyer, best known as the genie in Ray Harryhausen’s The 7th Voyage of Sinbad. Middle Right: Robby, Eyer, Diane Brewster and Philip Abbott on art director Merril Pye’s computer set, the film’s only suggestion of production value. Bottom: producer Nicholas Nayfack and director Herman Hoffman during location filming. Nayfack died in 1958, shortly after its release, at the age of 49.
