I think it was Alfred Hitchcock who said 90 percent of successful moviemaking is in the casting. The same is true in life. Who you are exposed to, who you choose to surround yourself with, is a unique variable in all of our experiences and it is hugely important in making us who we are. Seek out interesting characters, tough adversaries and strong mentors and your life can be rich, textured, highly entertaining and successful, like a Best Picture winner. Surround yourself with dullards, people of vanilla safety and unextraordinary ease, and you may find your life going straight to DVD.

I also listened to hours and hours and hours and hours and hours of [J.F.] Kennedy, and I sort of built [ accent]. And then I got on set [of 'J.F.Kennedy' movie ] and forgot it.But that's what you want to do. You want it to just be real. And I think authenticity was better than - people always talk about when an accent doesn't work, and the phrase you always hear is, "It was inconsistent."

Intelligence is that aspect of human cognition that we haven't managed to emulate yet.

We shot every scene of mine in the entire movie in five days. All my coverage, everything. I left. They went back and shot everybody else around me. Insane. The part [Billie in Crazy Six] called for a handsome, coiffed cool guy romantic lead, and I showed up like you see him in the movie. And they let me do it.
