Connection to Forbidden Planet?
Just watched this as the bonus feature on the Forbidden Planet dvd. I originally assumed that this film would have no narrative connection to FP, and that it was simply a way to get more money out of the expensive Robby the Robot creation.
However, having now watched it, I noticed during the scene where the father takes Timmy to his work to show him Robby, he points out a picture pinned to a wall, which depicts Robby in the year 2390 (or something). He explains this picture was found amongst the work of a deceased professor who had worked there, and how had supposedly built a time machine, which the father thought was nonsense.
So, are we to assume that Robby the Robot was transported to Earth's past from the future - presumably the future Forbidden Planet depicted? Did the professor create the time machine, or did Robby get transported back by another means? Does this make The Invisible Boy a sequel to FP? And how exactly did Robby get transported back?
I always thought some sort of connection to FP would be likely, as they share the same screenwriter. The untold adventures of Robby the Robot! It's fun to ponder these things sometimes...
