I got a liberal education. A white guy, rapping as Bugs Bunny, on a quintuple-platinum album.

If everyone else is doing something, I have little or no interest in it. If you're known as this guy who can do any kind of sound or voice or whatever, somebody will go, "Do you do Christopher Walken?" "No." "Well, why not?" "Because everybody else in the world does it." My carpenter does Christopher Walken.

I was basically a sound engineer, I produced radio shows and stuff and had to splice tape in the old days. And you knew a sloppy edit when you heard it, because I had enough of them. But that stuff takes the magic out of it, if you need to know everything. Then you become omnivorous. Everything is tender, and as soon as you burn it up, you're on to the next.

Robin Williams understands sonic performances. He understands what it's like to change your voice up.

But the throat just kind of falls into line once you realize in your head what it is. You got to remember the musicality of a character you're going to do.

The only thing I have to say to people - try being the hero of your own world one day. Don't spend your life thinking about what somebody did or if they failed at this or if they did great at that or they got caught with a monkey, in a bathtub, having sex. You should at one point become the hero of your own world.

To me, it all comes down to things being character-driven. It's hard for me to look beyond that. CG and all this cool stuff - so be it. But to me, it pretty much begins and ends with character-driven plots rather than technologically-driven plots.
