All the characters I play are all inside of me in a way, and they're all different, the darkness, the lightness, whatever that is.

My plan was never to be an actor like my father...

A lot of times we associate Greenpeace and climate change and shrinking polar caps with heavy-handed, weighty material. It's somber stuff. But with Funny Or Die we thought we could put an interesting take on it. Make it a little more palatable, especially for young people who tune into the website.

I'm not very active on social media. I'm not on Facebook or Twitter or Instagram, or anything like that. But I think it's wonderful that they're out there. They're fantastic. I have a lot of siblings and friends that use it, and it's great for them. It's such a connected world.

When we were shooting in Shreveport, me and a couple of friends went down to Lafayette, because they had a big Zydeco music festival down there. We spent two days dancing to Zydeco music, eating fried alligator... It was one of the craziest festivals I've ever been to in my life, but I loved it.

As an actor, what's interesting is what's hidden away beneath the surface. You want to be like a duck on a pond - very calm on the surface but paddling away like crazy underneath.

When I was four or five, I would organise my cars and my action figures. I needed some kind of structure, I think.
