Although many films about gangsters preceded The Godfather, Coppola steeped his film in Italian immigrant culture, and his portrayal of mobsters as persons of considerable psychological depth and complexity was unprecedented.[270] Coppola took it further with The Godfather Part II, and the success of those two films, critically, artistically and financially, was a catalyst for the production of numerous other depictions of Italian Americans as mobsters, including films such as Martin Scorsese's Goodfellas and TV series such as David Chase's The Sopranos.
A comprehensive study of Italian-American culture in film from 1914 to 2014 was conducted by the Italic Institute of America showing the influence of The Godfather.[271][272] Over 81 percent of films, 430 films, featuring Italian Americans as mobsters (87 percent of which were fictional) had been produced since The Godfather, an average of 10 per year, while only 98 films were produced preceding The Godfather.
The Godfather epic, encompassing the original trilogy and the additional footage that Coppola incorporated later, has been thoroughly integrated into American life. Together with a succession of mob-theme imitators, it has resulted in a stereotyped concept of Italian-American culture biased toward the criminal networks. The first film had the largest effect. Unlike any film before it, its portrayal of the many poor Italians who immigrated to the United States in the early decades of the 20th century is perhaps attributable to Coppola and expresses his understanding of their experience. The films explore the integration of fictional Italian-American criminals into American society. Though set in the period of mass Italian immigration to America, the film explores the specific family of the Corleones, who live outside the law. Although some critics have considered the Corleone story to portray some universal elements of immigration, other critics have suggested that it resulted in viewers overly associating organized crime with Italian-American culture. Produced in a period of intense national cynicism and self-criticism, the film struck a chord about the dual identities felt by many descendants of immigrants.[273] The Godfather has been cited as an influence in an increase in Hollywood's negative portrayals of immigrant Italians, and was a recruiting tool for organized crime.[274]
The concept of a mafia "Godfather" was a creation of Mario Puzo, and the film resulted in this term being added to the common language. Don Vito Corleone's line, "I'm gonna make him an offer he can't refuse", was voted the second-most memorable line in cinema history in AFI's 100 Years...100 Movie Quotes by the American Film Institute, in 2014.[275] The concept was not unique to the film. French writer Honoré de Balzac, in his novel Le Père Goriot (1835), wrote that Vautrin told Eugène: "In that case I will make you an offer that no one would decline."[276] An almost identical line was used in the John Wayne Western, Riders of Destiny (1933), where Forrest Taylor states, "I've made Denton an offer he can't refuse."[277] In 2014, the film also was selected as the greatest film by 2,120 industry professionals in a Hollywood survey undertaken by The Hollywood Reporter.[268]
Gangsters reportedly responded enthusiastically to the film.[278] Salvatore "Sammy the Bull" Gravano, the former underboss in the Gambino crime family,[279] said: "I left the movie stunned ... I mean I floated out of the theater. Maybe it was fiction, but for me, then, that was our life. It was incredible. I remember talking to a multitude of guys, made guys, who felt exactly the same way." According to Anthony Fiato, after seeing the film, Patriarca crime family members Paulie Intiso and Nicky Giso altered their speech patterns to imitate that of Vito Corleone. Intiso was known to swear frequently and use poor grammar; but after seeing the movie, he began to improve his speech and philosophize more.[280]
