This captivating profile of Oscar-winning screenwriter Dalton Trumbo (1905-76), who was blacklisted by the House Un-American Activities Committee in the 1950s, is richly detailed with home movies, photos, archival footage and readings from his works and letters. Despite being banned from film work, he continued to write under assumed names and won an Academy Award (as Robert Rich) for his script for 1956's "The Brave One." The film is based on the play by Trumbo's son, Christopher Trumbo.
