The movie CITIZEN KANE has been and will forever be regarded as one of the finest films ever produced, including one of the best screenplays. The script won an Oscar for Herman J. Mankiewicz. Orson Welles and John Houseman also helped on the writing; though how much is still to this day debated. Orson Welles personal copy of the script was auction recently at Sotheby's and according to the description:

"...229 pages, folio, paginated and dated throughout but pages numbered to p.321 (of 325) to match the first draft, with additions on lettered pages (e.g. p."98-b") and cuts shown through the use of pages numbered as sequences (e.g. p. "270-291"), dated 30 April to 9 May 1940, cream cover inscribed twice "Mr Welles' working copy", three brass split pins, cover creased, stained, and nearly detached, script lacking final four pages, in a blue collector's box; together with a modern photocopy of the fourth draft, marked "final", dated 18 June 1940."
