Martin Scorsese has admitted two new mental patients to Shutter Island, his adaptation of Dennis Lehane's novel. Emily Mortimer, who will perform in the Neil Pepe-directed play Parlour Song starting March 5 at the Linda Gross Theater, and Jackie Earle Haley, who got an Oscar nomination last year for his role as a creepy perv in Little Children, will play mental patients in the mystery drama, the Hollywood Reporter tells us. They join Leonardo DiCaprio and Mark Ruffalo in the cast. They play two U.S. marshals who travel to a Massachusetts island to investigate the disappearance of a patient from a hospital for the criminally insane. Ben Kingsley, Michelle Williams and Patricia Clarkson also star in the film, which was adapted by Laeta Kalogridis from Mr. Lehane's 2004 novel. He also wrote Mystic River.
