Every time I was cast in a role, the director put a gun in my hand, so I figured I’d better learn how to use one. Then I found out I really liked it.

Don't mess with me! I'm a black-belt!

I got my training here in Chicago at the Goodman School Of Drama, and a lot of my personal work is usually internal work and stuff. Everything else that goes on is icing on the cake - your wardrobe, your makeup, whatever else you have to do.

I don't approach a role by saying I'll be unsavory or unlikable. I think all the roles I've done have been very passionate people who go to absolute extremes to make their points.

Time is definitely money, so if you screw up a day or a shot, you may not get a chance to go back and get that shot and redo that day.

You forget about it, after awhile. You forget that you even have it on. It becomes part of you. You get used to it, even the teeth and the contacts, which bothered the hell out of me. It ends up being something that is part of the role, and part of the thing that you're doing. After awhile, it just feels pretty damn awesome.

I was pretty confident that I'd be playing something, if James Gunn could convince Marvel Studios and Disney to cast me. He's involved with the casting too, but if he could convince them to go along with him and agree with getting me on the roster, then yeah, I would have voiced Groot. Not a problem. Groot is an awesome character.
