Brilliant, moody, a bit creepy. A noirish thriller. Stellan Skarsgard gives a wonderfully subtle performance in the lead role of a Swedish police detective suffering from sleep deprivation while on assignment in Norway. Stylistically the director and cinematographer effectively recreate the alienated and somewhat hallucinatory feeling of being sleep deprived and in a foreign country. There's more to the story of course, but to reveal those details would spoil the surprises. Be warned, if you like your movie heroes uncomplicated then stay away from "Insomnia".
