Plus, in animated form, they could get away with a lot more with Robin Williams' type of humor than in a live action setting. I've read some people suggest that if Robin Williams were still alive, he'd be the one doing the Genie again like James Earl Jones is doing Mufasa again for Lion King. I don't think a Robin Williams Genie would translate well to live action. In that regard, I would buy that a Will Smith Genie is better suited to live action, but that doesn't really hold a candle to an animated Robin Williams Genie.
