Shutter Island is a 2010 American psychological thriller film directed by Martin Scorsese. The film is based on Dennis Lehane's 2003 novel of the same tile. But the film itself is one of sitting on the edge of the seat, as it captivates the audience, as you want to find out more of the story as it goes on. There are moments through out the film that makes the audience question everything they see, as nothing is what it seems. So the use of enigma codes, are used to great extent in this film. So for that reason my film will contain enigma codes, so that the audience is always trying to second guess the film, but it will contain some action codes at the same time.
