Martin Mooney came into the film business in 1935 as a screenwriter after years of working in New York City as a playwright, newspaper reporter, columnist and press agent. In 1943 he joined PRC Pictures, where, in addition to screenwriting, he was in charge of advertising and publicity. Mooney's background in the rough-and-tumble New York City newspaper world was the impetus for PRC's specializing in the gritty urban crime dramas it was known for. The film for which Mooney will probably be best remembered is Edgar G. Ulmer's "film noir" masterpiece, Detour (1945).
