screenwriter  Herman J. Mankiewicz (qv) for writing the entire script for this  film, while alleging that Orson Welles (qv) "didnt write one line  of the shooting script". However, this conclusion has very little  factual basis, and was largely based on hearsay. The shooting script  was actually based on two scripts (written separately by Welles and  Mankiewicz) that Welles combined into one for the final version.
