When a moviegoer thinks of Leonardo DiCaprio, a few things probably come to mind: sailing on a very big boat with Kate Winslet in Titanic, perhaps; inhabiting the ambition and eccentricity of Howard Hughes in The Aviator; or maybe going toe to toe with Jack Nicholson and a wicked Boston accent in The Departed. What you don’t know is that this serious actor can be a little silly off-screen, as he reveals in this weekend’s cover story. “I’m actually an incredible goofball,” he says. “I do imitations and joke around all day.” By now, he most likely has a decent imitation of iconic director Martin Scorsese, since the two have collaborated on Gangs of New York, The Aviator, The Departed and Shutter Island, a thriller based on the Dennis Lehane novel that opens Feb. 19. Check out a montage of clips below from the movie, which also stars Mark Ruffalo, Michelle Williams and Max von Sydow.
