Titanic fame nearly sunk me reveals Leo.

Now eleven years later, DiCaprio, 34, confesses how the blockbuster film made him nuts as he was too young to be able to cope with sudden fame.

"As soon as people give you enough compliments and you suddenly have more power than you’ve ever had in your entire life, it’s not that you become an arrogant p***k, or you become rude to people, but you get a false sense of your own importance," Leo admitted.

"You’re treading in dangerous territory when you begin thinking you’ve altered the course of history. It was like a runaway train.

"I didn’t understand what was happening to me," DiCaprio divulged.
