Only a few things I see quesitonable: why would bambi have a voice? as far as we know, he's not even in the game!
Why would Lilo have a voice? Same as number one. And even if she was in game...
Dakota Fanning did not do the original voice of Lilo. As a rather big name actress, why would Disney get her to do the voice, when it would be cheaper, easier, and more authentic do just use Daveigh Chase, who does her voice on the TV show?
Also, a lot of those are merely confirmed characters with the voice actors who have played them in movies. Keeping in mind that there must be a budget for the game, it could be very hard to get a lot of the big names to sign on. (Though trust me, I'm praying and crossing just about every part of my body that we'll get depp, knightly, bloom, and rush in port royal like everybody else.)
So, sorry, those are just some discrepancies/oddities I see...
