I am just lucky, says Leonardo DiCaprio

London: Hollywood superstar Leonardo DiCaprio says career success is merely his luck.

The 38-year-old actor said he did not even realise what a massive hit `Titanic` was at the time, reported Daily Star. "I always thought of myself as the underdog. Getting your foot in the door is like winning the lottery," he said. The star is currently gearing up for 3D romantic drama ‘The Great Gatsby’, which will hit theatres next month. PTI
