Leonardo DiCaprio has said that he doesnt fit into comedy movies,as he is too "drawn" to tragic movie parts. The Hollywood superstar has mainly played dramatic characters in his 18-year career,in films like Oscar-winning Titanic,Romeo + Juliet,and Gangs of New York. And now the 34-year-old actor is starring in forthcoming Martin Scorsese thriller Shutter Island. DiCaprio has said that he was quick to sign up to the project after reading the dark script. "People say I do tragic characters,but I find them very interesting and more compelling. I'm drawn towards them, Contactmusic quoted DiCaprio as having told Total Film magazine. He added: "I want to be moved during a cinematic experience and this movie changes form in a lot of ways. No-one is going to see this movie and say it's not interesting."
