text:  The film was also somewhat autobiographical for Rossen , relating to his dealings with the House Un @-@ American Activities Committee . A screenwriter during the 1930s and ' 40s , he had been involved with the Communist Party in the 1930s and refused to name names at his first HUAC appearance . Ultimately he changed his mind and identified friends and colleagues as party members . Similarly , Felson sells his soul and betrays the one person who really knows and loves him in a Faustian pact to gain character .
