I see your point. I just think it's too bad that this VFX supervisor seemed at all SURPRISED to find that a voice artist did more than "just the voice." It shows that we don't give voice talent the credit they deserve as actors.
I admit that I'm getting a bit bent out of shape over wording, but the way the article refers to "actors" and "voice talent" as though they're different entities, just makes it worse. Seems like they're propagating the wrong idea here.
