In Tomás Bascopé’s sweaty, low-budget Bolivian noir (2009), two robbers and their victim get stuck in an elevator over a three-day weekend. As the power dynamic shifts back and forth with possession of a revolver, they terrorize each other over control of their meager resources (a pack of cigarettes, some junk food), but eventually the delirium caused by heat and hunger begin to break down the social distinctions between them. Bascopé’s handling of the confined space, supported by some punchy digital camerawork, is an object lesson in shoestring craftsmanship; however, a broadly comic subplot involving a vain security guard seems to belong in a different movie. In Spanish with subtitles.
