Shutter Island is a 2010 thriller-period drama film directed by Martin Scorsese and starring Leonardo DiCaprio. The film is based on the 2003 novel of the same name by Dennis Lehane. Production started in March 2008. Shutter Island was originally slated to be released on October 2, 2009, but Paramount pushed the release date to February 19, 2010. Paramount head executive Brad Grey blamed the recent economic downturn as the main decision behind the delayed release date.
