As part of his talking-head interview for Alexandre O. Philippe's documentary 78/52, author Bret Easton Ellis declares that the notorious shower scene in Psycho is the one element that makes Alfred Hitchcock's horror masterpiece certifiably brilliant. Ellis is mistaken, of course, but his notion fits Philippe's movie to a "T". There are forty-five minutes of context and insight here, surrounded by garishly flushable fluff. Before we even get to the interview subjects (all presented, incidentally, in film-school-chic black-and-white), Philippe sets the table with a confusing re-creation of Marion Crane's long and frantic drive to the Bates Motel, which plays as if Universal Pictures had refused to let him use any actual footage from Psycho (we eventually see some, thank God). The doc's centerpiece--a thorough breakdown of score, editing, performance, and Saul Bass' meticulous yet immediate-feeling storyboards--is worth the hassle, as long as you resist the impulse to check out early.
