New York, Nov 17 (IANS) Hollywood actor Leonardo DiCaprio insists he was too young to handle international fame after starring in blockbuster hit "Titanic" at the age of 23.

The 34-year-old became a heartthrob all over the world after landing the lead role in the 1997 film alongside Kate Winslet.

But DiCaprio admits he was not mature enough to cope with turning into a major Hollywood star overnight, reports contactmusic.com.

'Titanic began a period of rebellion for me. 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 arrogant and rude to people, but you get a false sense of your own importance," he said.

"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.'
