The sources for Citizen Kane, the 1941 American motion picture that marked the feature film debut of Orson Welles, have been the subject of speculation and controversy since the project's inception. 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 Writing (Original Screenplay) for Herman J. Mankiewicz and Welles.
