The New York Times documents that Joseph Columbo pressured producer Al Ruddy to remove all occurrences of "Mafia" and "Casa Nostra" from the movie "The Godfather".
An article on knowledgenuts.com claims that prior to their meeting, the word "Mafia" only appeared once in the screenplay. I can't find any corroboration of that claim.
I did some current searches of the screenplay, but can't find a version of the screenplay that contains either phrase.
Where in the original screenplay did those words appear?
