Now, THAT is a highly-unfair comparison. It's not the same thing.
Among other things, didn't they replace certain members anyway?
Replacing a human acting troupe is not like replacing cartoon voice actors or puppeteers. I mean, you can't replace Elvis, you can just get Elvis impersonators. Replacing the entire Marx Brothers with other comedians would barely mean they're the same troupe, replacing them with impersonators is just that... impersonators.
Cartoon characters and puppets are special. They're not real, they're not alive, so they can never really die, get sick, or walk out on a contract dispute. They're immortal. Only the behind the scenes people change. The voices sound different, the personalities at worst are a little skewed, but they're essentially the same character.
Heh heh... when you're an animation student everyone tells weird stories, most of them legends myths, rumors or exaggerations. Still, I wonder if the Windsor McKay "BAD LUCK!!!" speech at a party animators threw him was true.That's not true, of course. The only reason why Walt stopped doing Mickey's voice regularly was because Walt became way too busy with his ever-increasing responsibilities around his studio (working on movies, TV shows, Disneyland, etc.) to do voice-over work on a full-time basis.
But Wayne was just awesome as the mouse. Now, I always loved Goofy cartoons and Donald Cartoons, but I didn't enjoy Mickey on that level. Somehow, when they did House of Mouse and Mouse Works, they really let the character loose. I sound blasphemous on this, but he's one of the few characters to have better newer media than some of his old stuff.... really, I can't stop talking about Three Musketeers!
