I haven't purposefully set out to play heroes. I'm interested in playing the character who finds himself in extraordinary circumstances. But he's really either just saving himself or acting in the service of something that's important to him.

I had no expectation of the level of adulation that would come my way. I just wanted to make a living with a regular role in a television series.

Nothing shocks me. I'm a scientist.

I saw what luck and success I had as an opportunity to twist it up and do something different, so I've always sought out different genres and different kinds of characters.

It's time to change the conversation about nature to focus on what we all have in common: our shared humanity.

I don't want to be a slave to electronic devices. I don't want to be connected to my friends. I don't want to send snapshots of my dog and cute pictures of my family life to my friends and family. I don't want to be liked, by pushing a button. I use all of this technology to basically replace devices that I had in the past which worked just fine.

[In relationships with a directors] I want to be able to give and take, and I can't name what it is: respect, energy, investment in the task, focus, humor, intelligence, but I always feel responsible for taking the money.
