Leonardo DiCaprio gained fame for his role as Jack Dawson in Titanic, and has starred in many other successful films including Romeo + Juliet, Catch Me If You Can, and Blood Diamond, for which he was nominated for the Academy Award for Best Actor. Another Academy Award nomination came for his role as Howard Hughes in The Aviator, directed by Martin Scorsese. Leonardo DiCaprio has also worked with Scorsese in Gangs of New York, The Departed and Shutter Island. This working partnership brought comparison to the earlier working relationship between Scorsese and actor Robert De Niro, who also benefited from roles in Scorsese films early in his career.
