The Gatsby that I remember reading when I was 15 years old in junior high school was far different from the Gatsby I read as an adult.

At first glance, you read something on the page and it can seem one way, and you can have your decisions before you wind up on set about what that set is supposed to mean, but until you're actually there doing them, there's really no way to understand it.

(Acting) certainly comes-100 percent-from the need to be loved. Any actor who says this isn't true is lying.

I've never tried to reach a certain demographic of an audience or try to say: OK, now I'm going to do this type of film to transition myself into more adult roles. Or a romantic hero. Or whatever it may be.

Most of the time I just keep to myself. I think like what it would be like to be... someone else.

It was invaluable to have a dear friend who you have known for over a decade, be a partner in a film like Titanic. To have somebody that talented to work against, who's also your friend and who you know you have the best intentions for and vice versa, and who you intrinsically trust to give you their forthright honest opinion about what we're both doing - all that's something you can't really buy.

The challenge for me was not just the prosthetic work and how to move like an older man would move, but more so how to have 50 years of experience in the workplace and talk to a young Robert F. Kennedy as if he was some political upstart that didn't know what the hell he was talking about. That was the big challenge [in the J. Edgar Hoover mоvie].
