The movie I chose to watch is called “Shutter Island”. Shutter Island, released in February 2010, is a psychological thriller directed by Martin Scorsese. The story is set in Boston in 1954. The main character is a U.S Marshal, named Teddy Daniels, played by Leonardo Dicaprio. Teddy plays the role of a U.S Marshal. He is assigned to investigate a missing patient from Boston’s Shutter Island Ashecliffe Hospital along with this partner Chuck. The patient they are trying to find is named Rachel Solando. She had been admitted to this hospital because she had drowned her 3 kids. As he began his investigation he soon begins to realise that this place isn’t what it seems to be. As the movie begins, Daniels and his partner are shown traveling to Shutter Island to investigate the disappearance of a patient from a mental hospital. However, as the plot unravels we see that Daniels has a mental disorder of his own. Teddy seems to have more than one disorder or mental illness due to all the things he’s been through. One of the illness’s he has is Dissociative Identity Disorder. He shows two very distinct identities. He switches from being a mental patient who murdered his wife, to being a U.S Marshal investigating a mental institution. When he is in one identity he forgets about his other one. He also experiences many hallucinations, where he thinks he’s seeing a certain object but it really isn’t there and that is a symptom of the identity disorder. An identity that is not in control may nonetheless gain access to a consciousness by producing visual hallucinations. In this movie Teddy has a lot of sudden migraines, It is said that an individual who has an identity disorder will experience migraines, asthma attacks and bowel syndrome. He also has Schizophrenia. He constantly experiences hallucinations and is occupied with one or more at a time. Another disorder that is presented is Delusional Disorder.
