HIS movies have grossed over $1 billion at the box office, and is currently ranked in eighth place among the richest men in Hollywood, but it seems that money isn't the motivator behind 36-year-old Leonardo DiCaprio's never-ending success. I never knew which movies of mine made money and which didn't. When Titanic came out, people would say, 'Do you realise what a success this is?' And I'd say, 'Yeah, yeah, it's a hit.' The [money] stuff never mattered to me until I was into my thirties and got interested in producing," he told the October issue of GQ. But even now I say that unless you want to prove that you can carry a film with your name, continuously trying to achieve box-office success is a dead end.
