Often overlooked in Christopher Nolan’s filmography (including by me, until now), Insomnia remains a taut, intelligent, and deeply atmospheric psychological thriller—one that rewards revisiting with a more mature lens. Released in the wake of Memento, I initially dismissed it for its straightforwardness. There are no fractured timelines, no dreams within dreams, no folding cities or collapsing black holes. And yet, Insomnia may quietly be one of Nolan’s most accomplished works—precisely because of its restraint.
Based on Erik Skjoldbjærg’s 1997 Norwegian film of the same name, Nolan’s adaptation transplants the action to Nightmute, Alaska, where the sun never sets and guilt has nowhere to hide. This backdrop becomes more than just setting; it’s metaphor made physical. As Al Pacino’s Will Dormer descends into insomnia—haunted by an internal darkness he can’t outrun—the persistent daylight becomes oppressive, a blinding reflection of the truth he’s trying to bury. The irony of Dormer’s name (“dormir” meaning “to sleep” in French and Spanish) underlines the central conceit: this is a man running from sleep because he’s running from self-reckoning.
Pacino delivers one of the most quietly powerful performances of his later career here—far removed from his infamous scenery-chewing excesses. Dormer is a man at the edge of psychological collapse, and Pacino plays him as perpetually fraying at the seams: paranoid, exhausted, angry, but never cartoonishly so. There’s a deep sadness in the performance, and a growing sense of futility, as Dormer begins to realise he may not be the good man he thinks he is—or, more precisely, that his good deeds no longer outweigh his compromises.
This is not a good-versus-evil story. Nolan, even this early in his career, is far more interested in moral ambiguity than heroism. Hilary Swank’s Ellie Burr is the idealistic counterweight to Dormer’s compromised veteran. She admires him, quotes his cases back to him, believes in his myth—but gradually comes to see the human underneath, the weary and fallible man who has spent too long justifying the means. Enter Robin Williams as Walter Finch. In a chilling reversal of his usual persona, Williams is unsettling precisely because he’s so ordinary. There’s no maniacal villainy here—just a quiet, needy presence who floats at the edge of Dormer’s exhausted psyche. Finch is both antagonist and analogue: a reflection of what Dormer fears he’s becoming. When Finch calmly discusses their mutual crimes—as if they’re just two men caught in difficult circumstances—it’s as if Dormer is being invited to rationalise his moral failures. Finch is a test, a mirror, and a threat, all in one. Williams plays him with a controlled stillness that’s far more unnerving than any outburst could be.
At the heart of Insomnia is the age-old ethical dilemma: do the ends justify the means? Dormer’s entire career seems to rest on that equation. If bending the rules puts away killers, does that make it right? But when his methods come under scrutiny—coinciding with his own accidental killing of his partner—it becomes clear that self-preservation is part of the equation too. Nolan doesn’t answer the question. Instead, he lets Dormer ask it again and again—until finally, he’s too tired to run from the truth. Dormer’s refusal to let Burr throw away her integrity in the closing moments is quietly devastating. It’s the one thing he can salvage. His final moment of sleep, after resisting it for the entire film, is not just physical but spiritual. He finds rest only when he stops running.
On paper, Insomnia lacks the high-concept architecture of Nolan’s later works. But the themes are pure Nolan: duality, moral compromise, unreliable perception, identity under pressure. The setting may be remote, but it’s as existentially foggy as Inception’s dreamscapes or The Prestige’s layered personas. And yet, it’s also his most human film. There are no grand twists or interstellar metaphors—just a man trying to live with what he’s done. Nolan's trademark visual control is already evident here, from the hazy, washed-out cinematography (courtesy of Wally Pfister) to the fragmented editing that mirrors Dormer's disorientation. The film's psychological texture is enhanced by a sound design that emphasises subtle disruptions: footsteps in water, the buzz of a fly, the echo of a gunshot. It’s immersive and immersive because it's simple.
Insomnia may not be the most showy entry in Nolan’s catalogue, but it might be his most emotionally mature. It’s a film about compromise, not glory; about conscience, not conflict. That it does this within the framework of a gripping, perfectly paced thriller is no small feat. And that Nolan—just two films into his career—had the confidence to explore these themes with such subtlety speaks volumes. It's a deeply thoughtful and tightly constructed psychological thriller that shows Christopher Nolan at his most quietly assured. Anchored by a career-highlight performance from Pacino and a haunting turn from Williams, Insomnia is a film about what happens when you can no longer sleep through the things you've done. It deserves far more credit than it gets.
