SYNOPSIS. The year is 1954, at the height of the Cold War, when U.S. Marshal Teddy Daniels (three-time Academy Award® nominee Leonardo DiCaprio) and his new partner Chuck Aule (Mark Ruffalo) are summoned to Shutter Island to investigate the implausible disappearance of a brilliant multiple murderess from a locked room within the impenetrable Ashecliffe Hospital. Surrounded by probing psychiatrists and dangerously psychopathic patients on the remote, windswept isle, they arrive into an eerie, volatile atmosphere that suggests nothing is quite what it seems. Leonardo DiCaprio said he was faced with his most challenging role yet in the new gothic thriller Shutter Island .
DiCaprio told a press conference in London he needs to "switch off" outside work in order to survive such demanding roles.
"By sheer necessity to survive the film-making process I do switch off when I go home because if I don't, especially in roles as demanding as this... Look, ultimately I'm challenged by these types of characters. This is the most challenging one to date for me. Physically yes but emotionally more so."
