"To begin with, some facts. Warhol bought a 16 mm Bolex camera and started making films in 1963. Almost all his films were made in the five-year period from 1963-1968. As Michael O’Pray has pointed out, these years can be roughly divided into three phases: (1) 1963-64: silent, relatively short B&W films made with the Bolex, like Kiss, Sleep, Eat, Haircut, Blow-Job, and the Screen Tests; (2) 1964-66: longer films, often an hour or more, with sound, like Beauty #2, Kitchen and The Chelsea Girls; (3) 1967-68: an attempt to build upon the commercial success of The Chelsea Girls, with a slightly tighter and clearer, more realist narrative, probably under the increasing influence of Paul Morrissey. Films in this phase include: My Hustler, Nude Restaurant and Lonesome Cowboys. Valerie Solanas shot Warhol in 1968, which abruptly ended his active, hands-on filmmaking activities. He did continue to sign Morrissey films like Flesh, Trash and Heat over the next couple of years."
