People care who do vo's in games now?
Charlie Murphy could've been hilarious as CJ... IF he had the lines(script) which would allow him to be so. If not, then it wouldn't be any different than hiring some random va. On that note, who the hell is Young Maylay?
As a matter a fact, would people even be the least bit more interested in the game simply because the va's are "famous"? Then again..... *looks at "Shark Tale" voice credits...
