Hollywood on Trial (1976)

This taut look at the Hollywood blacklist interweaves footage from congressional hearings in the late 1940s with then-contemporary interviews, including with Dalton Trumbo after he spent 10 months in prison for contempt of Congress. John Huston, a critic of the political witch hunt against anyone suspected of communism, adds propulsive narration to this harsh look at an ugly chapter of American history.
