The Invisible Boy

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.
