Would've agreed a year ago; but, after supporting an ai game and seeing how difficult it is to keep the models in check for even the simplest things I'm not so sure anymore. I think smart developers will use it to smooth out animations and, at the very least, replace the overpaid VA's but full on animations? No, it's more than 2 years away - unless you count slop, there will be a lot of that
Edit (after actually watching the movie): Holy shit that's the worst use of AI for voiceover I've seen yet. Literally windows tts - would've been better with just text like he had in his early movies. Did not help that the vid itself was very lame
