Insomniatakes place in the small town of Nightmute, Alaska. The rather barren but beautiful setting is established by fly-over shots of the detectives' plane flying into town. In this scene, it is also shared that Nightmute is far from other cities,emphasizing the remoteness and isolation of the location. Even still, Dormer’s drama still follows him north. As the hotel keeper tells him, “There are two kinds of people who live in Alaska: the ones who are born here and the ones who come here to escape something else.” It turns out Dormer is the latter.
The film was shot near the real town of Nightmute, with many of the establishing shots being in Alaska and British Columbia.

The setting also allows for exciting chase scenes and explorations of specific locations. This comes up in scenes like the chase over the floating logs or the chase through the fog, leaning into the particular qualities of the Alaskan setting.

Metaphorically, he is also asking for rest from the stress and pressure he has been under since the Internal Affairs investigation began. If Burr heeds his warning, the investigation will end with his death and will finally be over.
