a cinematic axiom defining classy, "artistic" nudity; Hollywood nudity is typified by exploitative close-ups and medium shots that both light and frame titties for the clearest view possible of the entire upper torso; art cinema, conversely, tends to abide by the one-titty rule, by which, through either framing, lighting, or, staging, or some combination of the three, only one nipple is visible at a time.
Sure David Cronenberg's "Crash" is possibly the most sexually explicit movie of the notorious pervert's career, but the Canadian master is careful throughout to observe the one-titty rule.
