This is true in a way, but also not. Depends on how you look at it. Disney made a deal with Robin Williams and they cheated him. He said not to use his character Genie is marketing for toys and such, and to only take up 25% of the advertisement poster. Disney agreed, and did it anyways. Disney tried to give him a Picasso painting worth 1 million dollars and Williams was still upset. Robin Williams was cheated, and it wasn't until Joe Roth took over and made Disney apologize publicly to him that Williams decided to mend the friendship with Disney again. Thus, recording his voice in the third Aladdin film!
..I'm not sure why I felt the need to post this. I'm just a little bored.
