Hollywood star Leonardo Dicaprio is backing director Martin Scorsese to win an Oscar for THE DEPARTED, and finds it ridiculous the film-maker has never won an Academy Award. Despite making acclaimed movies including Taxi Driver, MEAN STREETS and Raging Bull during his four-decade long career, Scorsese has never won an Oscar, and DiCaprio insists the snub is "almost a practical joke". The 32-year-old actor, who has starred in Scorsese movies Gangs of New York, The Aviator and The Departed, says, "It would be wonderful if this film was rewarded, I think it very much deserves it. And I certainly think (Scorsese) does. It's quite long overdue, almost a practical joke at this point that that hasn't happened." However, Scorsese admits he doesn't expect to win the Oscar, saying, "I learned a long time ago, with Mean Streets and Taxi Driver, that you can't make a film to get the golden statue. And if you try it doesn't work."
