I know what I saw the first time I saw the movie. None of the subsequent times did these scenes appear. But the film also melted in the projector at my first screening too.
Granted, I did own all of the original comics but I could quite easily differentiate between Marvel's lousy artwork and the live action shots.
But I also had a Meccano Cinevue with two Star Wars cartridges that had these scenes on one of them. I would give just about anything to find those again.
