Martin Scorsese's 2010 psychological thriller set in a mental institution is Shutter Island. The film stars Leonardo DiCaprio as Edward “Teddy” Daniels, a U.S. Marshal investigating the disappearance of a patient from Ashecliffe Hospital for the criminally insane.
The story takes place in 1954 on a remote island in Boston Harbor. Teddy and his partner, Chuck Aule, encounter evasive doctors, restricted hospital wards, unsettling clues, and apparent government experiments. The mystery gradually shifts from a missing-person investigation into a disturbing examination of trauma, guilt, memory, and delusion.
Shutter Island was adapted from Dennis Lehane's 2003 novel. The screenplay was written by Laeta Kalogridis, and the cast includes Mark Ruffalo, Ben Kingsley, Michelle Williams, and Patricia Clarkson. A common mix-up is confusing the title with The Island, a separate 2005 science-fiction film. Shutter Island was released in the United States on February 19, 2010.
