How to watch The Thin Blue Line
1988 · Errol Morris · The Thin Blue Line on Sightlines
4 things to watch and listen for on a first viewing, without spoilers, and 3 more once you have seen it. Each names something you can see or hear, the pattern it belongs to, and what noticing it gives you. How these keys work.
On a first viewing
Watch how the reenactments look lit like a film noir. (camera)
High contrast, saturated color, asphalt black and neon and rotating red light, a nocturnal palette that announces itself as staged rather than raw footage.
Payoff: The film tells you upfront that everything you're seeing is a representation, not the event itself.
Notice how the shooting gets restaged differently for each witness. (cutting)
Morris returns to the same roadside again and again, and small details keep changing, where the car sits, who's at the wheel, so the versions never converge.
Payoff: Repetition here corrodes certainty instead of confirming it. In the reading: crystalline-description. The reading calls this crystalline description: a version that only ever refers to other versions, never to a stable fact behind them.
Watch for the milkshake arcing through the air in slow motion. (setting)
Morris photographs an ordinary detail, a spilled drink, a falling clock, a police report, with the reverence usually reserved for a murder weapon.
Payoff: You watch a small, absurd fact get elevated into evidence right in front of you. In the reading: fetish. The reading calls this a fetish: a small object charged with more evidentiary weight than it could possibly carry.
Listen for the looping score under even the most routine testimony. (sound)
Philip Glass's arpeggios repeat and build under interviews that would otherwise sound flat and administrative, lending them a sense of fate.
Payoff: The music makes ordinary statements feel like they are already part of a verdict.
The 3 rewatch keys open on this page when you choose "Seen it?".
Carry this in: Watch the milkshake arc through the air. The film already knows you can't trust your own eyes.
