On Orson Welles' Touch of Evil (1958) and the formal argument of its opening sequence.

The opening sequence of Touch of Evil is the most studied long take in American genre cinema: a continuous shot that runs over three minutes and covers the planting of a car bomb, the car's journey through a Mexican border town, and the explosion that initiates the film's narrative.

The shot is doing several things at once. It establishes the setting with a geographical comprehensiveness that cuts cannot achieve: you move through the space, you understand the layout of the town, you feel the density of the population. It establishes the visual register of the film: busy, slightly over-lit, slightly too much going on.

But the shot is also an argument about what genre can do: the three-minute take creates a sustained unease that is different from the anxiety of cutting. The car is moving, the bomb is ticking, and you cannot look away because there's nowhere to look away to. The continuous shot is a formal representation of fate: this is happening, it will not be interrupted, and you are going to watch it.

Welles understood that the single-take is not primarily a technical achievement. It's a claim about the relationship between the camera and the event: the camera witnesses, it does not construct.
