When you do 'Before Sunset,' you know while it's a limited audience, there was a very small group of people that love 'Before Sunrise.' You feel a certain pressure to make sure that you uphold a level of quality that has been a bar. You set a bar and you have to at least match it.

Alejandro Amenábar is a very interesting filmmaker. I had really liked The Others, which was a movie he made with Nicole Kidman a few years ago. He made a very compelling case about how much he wanted me to be in this movie. Whenever a really passionate, talented filmmaker seems to have an interest in me, I take it very seriously because I like to work.

Often you see a famous actor who says they produced something, when all they did was claim to have an idea at a dinner party and make three phone calls.

I remember staying up all night waiting to see the first screening of Cape Fear because you knew that every time Robert DeNiro had a performance it was going to be revelatory. Then DeNiro hit this place, he seemed like he was done with the emotional cost of impaling himself like that, and he dedicated himself to comedy.

The drones are really interesting - how have the troops withdrawn from Afghanistan? Because we've upped the drone strikes and most of the country doesn't even really know what that means or who we're killing or... it's such a new weapon that we don't know what the long term impacts of that kind of military action is going to be.

One of the hardest things about my job is that there kind of is no one rulebook that applies to all situations.

And the best films feel like a fist punching you in the solar plexus and all elements of the filmmaking process - the acting, the design, the cinematography, the music, is all working to one end.
