Making really great music, making really great films, writing great books is an antidote to all of that. And, as people, as artists, some of the massive disruption that technology is causing is so exciting, the way that people can share creativity now.

As an actor, I don't have any politics. As an actor, I'm driven more by an authentic - I would say an obsessive-compulsive-disorder level-fixation on mimicry, tonality of voice, to literally imitate something until I can just disappear into it.

Remarkably, there's no green screen in 'Leaves of Grass' movie. There is motion control. Technically, there were all sorts of challenges, but really the soul of it is Edward Norton talent. You write these characters when you write a movie, and all you can hope for or depend on is that your actors will elevate the material.

I had a huge advantage with Edward Norton because he's directed a movie before, so one thing he appreciates is how hard my job is, he's very sensitive to that. We actually ended up finishing "Leaves of Grass" a day early.

I've observed over and over that people seem to get a much deeper sense of fulfillment out of something they've done as an act of service than out of the things they do for themselves.

As an actor, if you step to the side and you look at [Thornton's performance] technically, and you try to imagine doing what he was doing, most people would panic. Most people would be on the set, and they would be panicking, going, "I'm not doing anything!" All the ham instincts in you would be screaming, "You've got to indicate something here." And it's beautiful, in a way. And so I appreciate, even as an audience member, the courage that it takes to be... frankly, to be subtle.

I just don't think most of us are aware how much of what we throw away ends up in the ocean, for starters. Plastic bags are among the worst. The US is actually falling behind the curve on that score. China and many other countries have already banned the production and use of thin plastic bags.
