This illustrated overview presents a comprehensive comparative analysis of Screwball Comedy and Film Noir, two popular Hollywood genres that emerged at nearly the same time. Despite their contrast in tone and theme, ""Screwball"" and ""Noir"" have many narrative elements in common. The author defines the two, discussing their historical development and related conventions and offering detailed analyses of a number of films, among them The Lady Eve and His Girl Friday on the ""Screwball"" side, and Gilda and Sunset Blvd. on the ""Noir"" side. Two appendices offer a comprehensive filmography of Screwball comedies from 1934 through 1954 and a selected filmography of Film Noir titles, covering 1941 through 1958.
