Because he was not permitted to work due to the Hollywood blacklist, Trumbo wrote the story - and was nominated - under the pseudonym Robert Rich, who had nothing to do with the film industry and is a nephew of the King Brothers, producers of the film. Although there were rumors at the time that this was the case, the film's producer repeatedly denied the suggestion. It was not acknowledged until several years later that Trumbo had been the writer. He finally received his award on May 2, 1975, presented by then Academy president
Walter Mirisch, shortly before his death - although the official screen credit was not changed until many years afterward.
