Director Christopher Nolan follows up his breakthrough sophomore film Memento with this remake of a stylish Norwegian thriller. Al Pacino stars as Detective Will Dormer, a Los Angeles Police Department legend who temporarily escapes an internal affairs investigation that may ruin his career by traveling to Nightmute, AK, the remote site of a murder that has the local authorities flummoxed. Along with his partner, Hap Eckhart (Martin Donovan), and the small town's wide-eyed rookie investigator, Ellie Burr (Hilary Swank), the exhausted Dormer probes the brutal slaying of a teenage girl who was rumored to have a secret lover. A clever ruse quickly lures the killer into a police trap, but the suspect escapes and a tragic accident at the scene leaves Dormer at the mercy of the murderer, a pulp crime novelist named Walter Finch (Robin Williams). As Finch plays a dangerous game of extortion with Dormer, the detective's mental health deteriorates rapidly from guilt over his complicity in a crime and sleep deprivation compounded by the lack of darkness in the land of the midnight sun. Meanwhile, the bright and dogged Ellie continues putting the pieces of a complex puzzle together despite Dormer's skillful attempts to lead the investigation toward the right suspect, but away from his own malfeasance. Insomnia co-stars Paul Dooley, Nicky Katt, Maura Tierney, and Jonathan Jackson.
