When I was doing 'This Boy's Life' I wanted to be as old as Robert DeNiro and as experienced as him and have the same respect as he did in that movie.

As far as my own dreams, I'm not a big dreamer, I think obviously we suppress things in life, emotions and thoughts, and we should wake up and look at that.

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.

I don't think there's a specific science you can put on dream psychology. I think that it's up to the, obviously, the individual.

I didn't worry about what DeNiro thought... I went in, looked him in the eye, and got the part. I was confident, even though I'd never done anything like it before. Now I realise it was ignorant confidence-I had no idea.

It's a hard concept for me to wrap my head around to completely sacrifice any sort of love in your life, to never experience that on a personal level.

You see, I think negative emotions are always trumped by positive emotions.
