The Invisible Boy is a 1957 black and white American science fiction film from Metro-Goldwyn Mayer, produced by Nicholas Nayfack, directed by Herman Hoffman, and starring Richard Eyer and Philip Abbott. It is the second film appearance of Robby the Robot, the science fiction character who "stole the show" in Forbidden Planet (1956), also released by Metro-Goldwyn-Mayer. According to an implied, subtle back story in The Invisible Boy, the robot is the same character as that in Forbidden Planet, which is set in the 23rd century; Robby is brought back to the film's mid-20th century era by time travel.

Philip Abbott was an American character actor. He appeared in several films and numerous television series, including a lead role as Arthur Ward in the crime series The F.B.I. Abbott was also the founder of Theatre West in Los Angeles.
