Shirley Clarke’s 1967 study of a black male prostitute, Jason Holliday, was a pioneering study of the cinema verite movement—a 105-minute record of Jason conversing, performing, confessing, dissolving. It’s an intense, commanding film, though Clarke’s wholesale appropriation of Jason’s life and pain for the purposes of art causes a moral queasiness that, typically for the verite movement, is never addressed or acknowledged.
