...Insomnia (2002)

You don't need to be Hercule Poirot to solve the mystery in a movie when one of three Academy Award winning actors shows up for the first time halfway through it. Fortunately the transparency of the plot (and its outcome) doesn't detract from the atmosphere established by director Christopher Nolan in Insomnia, an intriguing story of two Los Angeles cops who travel to Nightmute, Alaska, where darkness never falls. Hilary Swank, Al Pacino, Maura Tierney, and a somewhat subdued (but still annoying) Robin Williams do admirable jobs that, coupled with the breathtaking Alaskan landscape and the allure of the titular ailment itself, make this one a worthwhile journey up north.
