Conscience won't let him sleep

In the sleepless nights of Alaska, a detective, investigating the death of a local girl, finds himself in a dead end and digs his own grave deeper and deeper. Insomnia (2002) is Christopher Nolan's masterpiece featuring Al Pacino at his best and Robin Willians in a rarely serious role. A remake of the 1997 Norwegian film by Erik Skjoldbjærg.
