Ben Kingsley and Mark Ruffalo have signed up to star alongside Leonardo Dicaprio in Martin Scorsese's upcoming movie SHUTTER ISLAND. DiCaprio will play a U.S. Marshall investigating the disappearance of a mental patient in the 1950s-set film, which marks the fourth time he has teamed up with director Scorsese. Kingsley will star as a mental asylum's chief physician. Recent reports linked Sylvester Stallone to the project, although it remains unclear whether the ageing action hero is officially onboard.
