The classic film 'Citizen Kane' officially credits Herman Mankiewicz and Orson Welles for the Oscar-winning original screenplay. However, both Mankiewicz and Welles have claimed the script was primarily a product of their own creation. The controversial script in its day was considered the greatest movie script ever written and today still ranks fourth on the 101 greatest screenplay list by the Writers Guild of America. The heated debate over 'Citizen Kane's true authorship has raged for almost eighty years and is the subject of David Fincher's latest film, 'Mank'.
Who do you think really deserves the credit for writing 'Citizen Kane'?
