I love playing all kinds of roles. I hope it doesn’t sound too pretentious, but I always feel human nature is like a piano, and there are 88 keys, and there are some white keys and some black keys, and each character is a different chord on the piano. Basically, I hope that in the course of my life, I will have played all 88 keys. So, I’ll have played heroes and villains and princes and kings and warriors and beggars and thieves and lovers and fathers and wizards and all of those things. That is why I’m an actor… I love studying people.

I always thought of running as just dancing forward.

You can’t really legislate for the decisions that your heart makes.

One of the great flaws that we all share is that we think everyone else is cooler, everyone else is sexier; everyone else has all the answers. That was me too.

I was informed yesterday that there's a Twitter account for my laugh. Very hard to get used to things like that. Pretty amazing.

Loki in 'Thor' is the most incredible springboard into a sort of excavation of the darker aspects of human nature. So that was thrilling, coming back knowing that I'd built the boat and now I could set sail into choppier waters.

You've got to do something, even if it's just to kick-start the day. I use music. And running.
