Stream Arthur Miller, Elia Kazan and the Blacklist: None Without Sin (2003) : Online. Director Elia Kazan and playwright Arthur Miller were once best friends and professional colleagues, to most that knew them then in both capacities as soul mates. Their politics were similar which was reflected in their work. Kazan was a Communist Party member for a few years in the mid-1930's, but Miller never officially joined the party ranks. Their relationship changed in the early 1950's when Kazan was subpoenaed to testify in front of the House Un-American Activities Committee where he named names of Communist Party members past and present.
