The authorship of the screenplay for Citizen Kane, the 1941 American motion picture that marked the feature film debut of Orson Welles, has been one of the film's long-standing controversies. With a story spanning 60 years, the quasi-biographical film examines the life and legacy of Charles Foster Kane, played by Welles, a fictional character based in part upon the American newspaper magnate William Randolph Hearst and Chicago tycoons Samuel Insull and Harold McCormick. A rich incorporation of the experiences and knowledge of its authors, the film earned an Academy Award for Best Original Screenplay for Herman J. Mankiewicz and Welles.
