'Insomnia' is a film with a lot of room for the director, who establishes a distinctive far-north location, a world where the complexities of the big city are smoothed out into clear choices. 'Memento' was one of a kind the thought of another film based on a similar enigma is exhausting. Why Nolan took on this remake is easy to understand. In this film and 'One-Hour Photo,' which played at Sundance 2002 and will be released later in the year, Williams reminds us that he is a considerable dramatic talent-and that while, over the years, he has chosen to appear in some comedic turkeys ('Death to Smoochy' leaps to mind), his serious films are almost always good ones. Williams has the smooth, open face of a true believer, a man convinced of his own case. Pacino is lined, weary, dark circles under his eyes, his jaw slack with fatigue. Their scenes work because Pacino's character, in regarding Williams, is forced to look at a mirror of his own self-deception. Pacino and Williams are very good together. Only a studio executive could explain why we need perfunctory action, just for action's sake, in a film where the psychological suspense is so high. These are thrown in as-what? Sops for the cinematically impaired, I suppose. There is also a scene involving a chase across floating logs, and a scene where a character is trapped underwater. Unusual, for a thriller to hinge on issues of morality and guilt, and Nolan's remake doesn't avoid the obligatory Hollywood requirement that all thrillers must end in a shoot-out. And the local detective seems to suspect something.

Right, detective? Pacino, sleepless in a land where the sun mercilessly never sets, is trapped: If he arrests Finch, he exposes himself and his own cover-up. He plays Walter Finch, who does not really consider himself a murderer, although his killing was cruel and brutal.

The face of the killer, the first time we see it, comes as a shock, because by now we may have forgotten Robin Williams was even in the film. In a nice development in the rewrite (credited to original authors Nikolaj Frobenius and Skjoldbjaerg, working with Hillary Seitz), the killer introduces himself into the case as sort of Pacino's self-appointed silent partner. In the Norwegian film, the local female detective begins to develop a circumstantial case against the veteran cop. It is easy enough to pin the murder on the escaping killer, except that one person knows for sure who did it: the escaping killer himself. The Pacino character sets a trap for the killer, but the suspect slips away in the fog, and then Pacino, seeing an indistinct figure loom before him, shoots and kills Hap, his partner from L.A. The pivotal event in both films, filmed much alike, is a shoot-out in a thick fog during a stakeout. Spoilers will occur in the next paragraph, so be warned. The development is the same in both movies the character is much more important in this new version, adding a dimension I found fascinating. Pacino takes a more physical approach: How much longer can he carry this burden? The story involves an unexpected development a third of the way through, and then the introduction of a character we do not really expect to meet, not like this. Stellan Skarsgard, who starred in the earlier film, took an existential approach to the character he seemed weighed down by the moral morass he was trapped in. Unlike most remakes, the Nolan 'Insomnia' is not a pale retread, but a re-examination of the material, like a new production of a good play.

That was a strong, atmospheric, dread-heavy film, and so is this one. 'Insomnia,' the first film directed by Christopher Nolan since his famous ' Memento' (2001), is a remake of a Norwegian film of the same name, made in 1998 by Erik Skjoldbjaerg.
