Timmie is a typical ten-year-old boy: he loves fun and mischief and hates to study. When his scientist father, in an attempt to improve Timmie's mind, plops him in front of the Super Computer, the boy learns more than how to beat his dad at chess. With designs on world domination, the computer has Timmie reactivate Robby the Robot and directs the metal hulk to do his bidding. But while Robby is an efficient minion, can he be made to harm the boy who gave him life? Written by Chris Stone <jstone@bellatlantic.net>

Possible sequel to Forbidden Planet?
4 April 1999 | by JeffG-4See all my reviews

Some movie trivia sleuths consider this film to be sort of a "sequel" to Forbidden Planet" (also a Nick Nayfack production). Look for a scene early in the film where the disassembled "Robby" is found in a present-day scientist's store room, with notes indicating the scientist had developed a way of going into the future, where he obtained the robot. Also in this room is a picture that the young boy comments on, showing "Robby" emerging from the Forbidden Planet saucer ship at the "Chicago Spaceport" in the year 2242, inferring that Commander Adams, Altaira, and the rest of the crew made it back to Earth safely after the Krell furnaces caused the explosion of Altair IV at the end of that film.
