There's always room. That's what the directors usually want. They want the performer to bring themselves and give what they have to give for the role. The smart ones allow that to happen because then it becomes even more organic within the performer's imagination. It becomes even more real. It's not always a given in other films, but when Gunn works, and we all work together in a collaborative way like that, it becomes a given that you bring it. It becomes a lot of fun.

Actors are actors. They're all buddies. I've done so many movies and TV that you get to be friends with everyone. And the ones you don't get to be friends with, you simply don't work together with them again.

Actors basically do their thing on the set, and then you put all the pieces together, switch them around, and maybe put them a different way that looks better. We just give him everything he needs, and then he goes in and does his thing.

When you think of it I haven't really done a lot of horror. It's amazing: I have done some really good ones, but I haven't done a lot of them.

I don't approach a role by saying I'll be unsavory or unlikable.

That's very cool. Absolutely! You want to know where this guy came from, but you also want to know about the relationship between him and Quill, and how they ended up living together, for the last 18 or 19 years, without killing one another. He's a strong young man, and it's because of Yondu.

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.
