Writing

On April 14, 1970, it was revealed that Puzo was hired by Paramount for $100,000, along with a percentage of the film's profits, to work on the screenplay for the film. Working from the book, Coppola wanted to have the themes of culture, character, power, and family at the forefront of the film, whereas Puzo wanted to retain aspects from his novel and his initial draft of 150 pages was finished on August 10, 1970. After Coppola was hired as director, both Puzo and Coppola worked on the screenplay, but separately. Puzo worked on his draft in Los Angeles, while Coppola wrote his version in San Francisco. Coppola created a book where he tore pages out of Puzo's book and pasted them into his book. There, he made notes about each of the book's fifty scenes, which related to major themes prevalent in the scene, whether the scene should be included in the film, along with ideas and concepts that could be used when filming to make the film true to Italian culture. The two remained in contact while they wrote their respective screenplays and made decisions on what to include and what to remove for the final version. A second draft was completed on March 1, 1971, and was 173 pages long. The final screenplay was finished on March 29, 1971, and wound up being 163 pages long, 40 pages over what Paramount had asked for. When filming, Coppola referred to the notebook he had created over the final draft of the screenplay. Screenwriter Robert Towne did uncredited work on the script, particularly on the Pacino-Brando garden scene. Despite finishing the third draft, some scenes in the film were still not written yet and were written during production.

The Italian-American Civil Rights League, led by mobster Joseph Colombo, maintained that the film emphasized stereotypes about Italian-Americans, and wanted all uses of the words " mafia " and " Cosa Nostra " to be removed from the script. The league also requested that all the money earned from the premiere be donated to the league's fund to build a new hospital. Coppola claimed that Puzo's screenplay only contained two instances of the word "mafia" being used, while "Cosa Nostra" was not used at all. They were removed and replaced with other terms, without compromising the story. The league eventually gave its support for the script. Earlier, the windows of producer Albert S. Ruddy 's car had been shot out with a note left on the dashboard which essentially said, "shut down the movie—or else." However, it was revealed in August 1971 that Ruddy personally met with Colombo family head Joseph Colombo, Columbo's son Anthony and about 1,500 delegates of Columbo's Italian-American Civil Rights League when he was developing the film, with the first meeting being held on February 25, 1971. Ruddy would also hold numerous meetings with Anthony Colombo. These meetings led to Ruddy agreeing to base the film on individuals and assuring that it would not defame or stereotype Italians. To further ensure trust, the words “Mafia,” “Cosa Nostra” and all other Italian words were removed from the script. It was even reported that Anthony Colombo eventually made Ruddy an honorary captain of the League.
