I started acting when I was 13 years old and I feel like I really admire actors who are these kind of amazing shape-changing people, that they almost can turn themselves into other people.

In your mid-twenties, the paint is still wet on who you are.

There's only so often you're going to have an opportunity to contribute at a high level and that you should be grateful whenever one presents itself and not take it lightly.

It's so hard for every young person, trying to figure out the adult you want to be.

It's interesting to get older and realize that part of your job growing up in this profession is to help the next generation. More and more, with Boyhood and with Ellar Coltrane and with Emma [Watson], I start to see that role. There's no better way. Nobody wants advice, so you can't really give it. You just have to try to wish them well on their journey.

Well, there's a great Marlon Brando quote that to do something well you have to spiritually marry your director. You have to be making the same movie they are in that you have to try to help their imagination be better, and more full, and more fully realized, but you can't have a different imagination because then you end up - and you see this a lot in movies - where it feels like they were making five different films.

Whenever actors tout off about doing their own stunts, it's always ... they're so protective of you that I always know these stunt guys are so good [and] they're never going to put you in danger. But it's fun to do something kind of exciting, even something as simple as driving 70 through a tunnel with five motorcycles ... it sounds simple, but it's actually really nerve-wracking.
