*shrugs* My references on the matter were pretty much the same as the rest of you. lol That being Wikipedia, IMDB (which currently credits David Warner as Sark/MCP) and various other people. However, like a few have said, if you listen closely, you can tell it isn't him. He does a very very good representation.
This is off the subject, but related. Cam Clarke voiced Simba for the Pride Lands world, wheras Matthew Broderick voiced him in the movie and he does such a good job that you almost can't tell the difference either. They picked good voice actors for this one. Cam Clarke, by the way, voiced He-Man/Prince Adam in the 2002 Masters of the Universe series.
Among other things. Hehe
I think the first KH game actually listed the voice actors in the manual somewhere. This time, the voice actors aren't listed anywhere except in the credits, which is a shame.
EDIT: By the way, has anyone here come across an interview with Bruce about being involved with TRON again in KH2? I know that at one time, someone or a couple of someones on this site was able to get a number of the cast to actually register here or at least get an interview. Is that do-able again? I'd really like to know what he thought of the whole experience and the end result and also what Steven Lisberger may have to say if he has seen it.
