It's amazing to completely focus on something for four, five or six months, have it completely consume your life and be constantly thinking about somebody else's set of circumstances and how they would react to something. I find it fascinating. It's rewarding and on a professional and personal level.

Acting is the only time when I truly maintain the spontaneity that I want to be present at all times.

I cheated a lot, because I just couldn't sit and do homework. I usually sat next to someone extremely smart.

I like to prepare as much as possible beforehand, but there's definitely that element of fear when you're on set, and you have to be conscious of it and use that fear to drive you to work harder.

There's so many intangible forces that come into play when making a film, I have no idea what the public will ultimately think of something that I do, let alone critics.

A single idea from the human mind can build cities. An idea can transform the world and rewrite all the rules.

I know a lot of the intense moments in 'Titanic' were made that much easier and were pushed to even further limits because of that relationship.
