Your basic kiddie sci-fi fare, notable only for the presence of the beloved "Robbie the Robot" from the film "Forbidden Planet." Whether MGM used him here because of his popularity or to save a few bucks is certainly debatable. The story, such as it is, concerns a boy who befriends Robbie, who, it turns out, can not only make him invisible (so he can avoid his parents and revenge himself on the neighborhood bully), but wants to take him to the moon as well, at the bidding of his true master -- a supercomputer with ego issues.
Pretty much standard.
