I can't imagine a more profoundly exciting experience than I had working on 'Avatar.' And whether I'm ever part of it again, I'll always be very proud that I was a part of it.

My job, professionally, is tapping into stuff. We've all got it. But, I just am fortunate enough that, beyond the age of 11, it's what I do professionally.

Occasionally, I have time to go to the theater, and I think for a minute, 'Man, I'd really love to be doing a play right now.' Because I loved doing plays when I was doing them. Then I think, 'I want to do it right now, but will I want to do that Sunday matinee in six weeks?'

My favorite show from the '60s was 'Combat.' And maybe 'The Man From U.N.C.L.E.'

Whether I appear in 'Avatar 2' or 'Avatar 3', I always feel I'm a part of the 'Avatar' team.

Your primary tools, as an actor, are observation and imagination. You can pretty much get everything you need from that, and you do. It brings back that element of pretend.

My advice to actors? To successful actors, it's, "sock it away," and unsuccessful actors, it's just, "Just keep at it. Don't do it unless you have to do it and if you have to do it, keep you've got to keep your instrument in shape. You just got to keep on getting better. If you're not getting better, you're standing still.
