Holy shit I don't think I've ever actually heard Mr Bean talk except for that goofy voice he used in Rat Race, so I had *NO* idea that he was the voice of Zazu. I never would have guessed that with all the time in the world.
I never understand the idea that these remakes should use the same voices. The original movie already exists. It's OK for this be different, in fact that's what makes it interesting at all.
Well, in this particular case, there's three things for using the same cast:
1) The movie will not actually be live action but animated, which means there's little reason to actually recast since it's not like they now have to get someone to BE Simba like they would have to get someone to BE Jafar. When you are actually making a cartoon into live action, your hands are tied with getting someone who looks the part VS getting the person who did the voice. Like, I don't think Gaston's voice looked anything like Gaston so obviously they would need to recast him for a live action adaptation. You don't have that issue with this movie.
2) I may be wrong about this but I'm pretty sure the entire voice cast of The Lion King is still alive so they *could* do it without needing to recast any role, if they wanted to.
3) The big one, they're using James Earl Jones, the original voice of Mufasa, as the new voice of Mufasa. So like they set the precedent by using an original actor from the original movie, and then went hard left with every other announcement after that. If they're going to recast everyone else they should also have recast Mufasa. It's going to be fuckin weird, for me at least, to have all these characters I've "known" for the past 20-something years have new voices except for Mufasa.
