Didn't Grandpa called Littlefoot by his name, when the gang arrived to the Great Valley?
I have a question. Bill Erwin is credited as voicing Grandpa on the 1st film. Yet in the short time Grandpa was in the film, I did not hear him speak. He laughed, but any actor with a speaking role could have done that. Is it possible that he spoke in a scene that also didn't make it into the movie yet was still credited?
But what puzzles me in that case is that pokeplayers laserdisc is also full cut and if I am right it was released at the same time as the first VHS copies.
I just checked and my copy is from 1989. Sadly, it's the cut version.
If it does than you have the full uncut version of the movie witch is great.
