Martin Scorsese to direct the film but Paramount refused. Coppola also, in his director's commentary on The Godfather Part II, mentioned that the scenes depicting the Senate committee interrogation of Michael Corleone and Frank Pentangeli are based on the Joseph Valachi federal hearings and that Pentangeli is a Valachi-like figure. Production, however, nearly ended before it began when Pacino's lawyers told Coppola that he had grave misgivings with the script and was not coming. Coppola spent an entire night rewriting it before giving it to Pacino for his review. Pacino approved it and the production went forward. The film's original budget was $6 million but costs increased to over $11 million, with Varietys review claiming it was over $15 million.

James Caan agreed to reprise the role of Sonny in the birthday flashback sequence, demanding he be paid the same amount he received for the entire previous film for the single scene in Part II, which he received.

Charles Bluhdorn, whose Gulf+Western conglomerate owned Paramount, felt strongly about developing the Dominican Republic as a movie-making site. Forza d'Agrò was the Sicilian town featured in the film. Unlike with the first film, Coppola was given near-complete control over production. In his commentary, he said this
