I know you're working on Boyhood with Richard Linklater. How's that been going? That's such an ambitious project.

It's one of the most amazing things I've been involved in and I can't wait for people to see it. We've been making these short films every year for the last 10 years, Richard Linklater and I--well, I'm not in all of them. It follows a young boy from first grade to twelfth grade, very simple. In just the period of a two-hour movie, you watch a human being grow up. It's almost like watching a flower bloom in time-elapsed photography. It's just two hours of the experience of growing up. We have two more years, and they're two important years because it's the finale of the movie. I think it's the greatest thing that Linklater's ever done. I think it's mind-blowing.

I can't wait.

Oh, it's so interesting. I mean, it's very simple, it's very humble. It's epic in the most fragile of ways.

Because it's like life.

It's just like life. It's so amazing watching these scenes. I don't want to talk too much about it because I want everyone to see it, but it's just amazing. For one minute you're watching a six-year-old boy, and it's so beautiful what Richard [Linklater] does with time: you don't ever see him go from six to seven, to seven to eight, to eight to nine. It's just all of a sudden you're watching a seven-year-old and [whispering] oh, his voice has changed... Are those whiskers...? Is that him with a girl...? A couple minutes ago he was just riding a bike with his buddies! It's so cool! [sighs]
