Dalton Trumbo, American author, screenwriter, and blacklistee (died 1976)

James Dalton Trumbo was an American screenwriter who scripted many award-winning films, including Roman Holiday (1953), Exodus, Spartacus, and Thirty Seconds Over Tokyo (1944). One of the Hollywood Ten, he refused to testify before the House Un-American Activities Committee (HUAC) in 1947 during the committee's investigation of Communist influences in the motion picture industry.

The Hollywood blacklist was the mid-20th century banning of suspected Communists from working in the United States entertainment industry. The blacklist began at the onset of the Cold War and Red Scare, and affected entertainment production in Hollywood, New York, and elsewhere. Actors, screenwriters, directors, musicians, and other professionals were barred from employment based on their present or past membership in, alleged membership in, or perceived sympathy with the Communist Party USA (CPUSA), or on the basis of their refusal to assist Congressional or FBI investigations into the Party's activities.
