Insomnia

Insomnia is another film that is directed by Christopher Nolan and was released on may 24th 2002. The film tells the story of a criminal investigation into the murder of a teenage girl in a remote town in Alaska. Two LAPD detectives named Will Dormer and Hap Eckhart are sent to assist local police with the investigation. Whilst the two detectives are in Alaska working on the case an internal affairs investigation is underway in Los Angeles surrounding cases that Dormer has been involved with, one of which involved him planting false evidence in order to get a man named Dobbs convicted for murder. Ekhart has been given the opportunity by Internal Affairs to testify against Dormer in return for immunity from prosecution.

The film then returns to the original murder case and Dormer concieves a plan to lure the murderer back to the murder scene, an old wooden cabin by the lakeside. The plan backfires when one of the officers involved draws the attention of the assumed murderer, causing him to flee into the fog that has gathered around the lake. Dormer and the other officers give chase, a shot is fired by the fleeing man and hits one of the officers. Dormer continues the chase and fires a shot when he sees a figure through the fog that appears to be holding a gun. When he gets up close to that person it is revealed that he has shot Eckhart rather than the fleeing suspect. Eckhart believes that Dormer deliberately shot him in order to prevent him from testifying against him in the Internal Affairs investigation before he dies. As a result of Eckhart's death another investigation is opened as to who killed him.

Throughout the remainder of the film Dormer's state of mind becomes increasingly impaired as he begins to suffer from insomnia due to the permanent sunlight that is prevailent in that part of Alaska due to its geographic location and the underlying guilt that he is suffering from as a result of shooting Eckhart and trying to keep it covered up. Dormer also begins communicating with the man that killed the teenage girl, with the relationship between the two men becoming more tense as the men essentially aim to psychologically manipulate each other in order to get what they want. The film culminates with the two men shooting each other dead leaving the viewer to wonder what the effects of that outcome will be.
