One doesn't expect to feel claustrophobic in Alaska, but that's exactly the effect when watching "Insomnia". The primary story is about the police investigation of the murder of a high-school girl in a small Alaskan town. Through the pull of old acquaintances and political necessity, two LA homicide detectives (Pacino and Martin Donovan) are dispatched to the scene to help the locals. The political necessity concerns a graft investigation in which the two LA detectives are key suspects. One is thinking of copping a plea, so they are spirited out of LA to avoid the investigative light. Then they find themselves in the 24-hour day of the Alaskan summer where the two plot lines collide; the murder investigation and the graft. And what a collision it is.
The insomnia of the title is suffered by the Pacino character, who can't sleep during the movie's 7-day span. And each day his eyes are more sunken, he's groggier, less focused. This parallels his descent into guilt, remorse, and desperation. But to provide any more details would be to give away key plot elements. "Insomnia" is gripping and it's best to see the movie cold.
The acting, especially Robin Williams as the key suspect in the child slaying, is top notch. Williams is made for these roles, he should kiss the suck-up feel-good stuff goodbye for good. The photography is excellent, Alaska never looked so ominous, and the direction delivers the goods. Highly recommended.
