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. Some of this film’s fans contend that the robot is the same character as seen in Forbidden Planet, which is set in the 23rd century, brought back to the film's mid-20th century era by time travel, and while there is no formal declartion supporting this by the studio, it is well supported within the film via dialog and a photo artifact showing Robby's arrival to Earth in 2309AD.
