- The cat in the opening scene was a stray. Francis Ford Coppola found the animal wandering around the studio lot and handed it to Marlon Brando. Its loud purring actually muffled some of the dialogue, which required the actors to re-record their lines later.
- Marlon Brando used cue cards instead of memorizing his lines. He believed that reading the words for the first time made his performance feel more spontaneous. Consequently, the crew hid script pages behind lamps, bushes, and even on the chests of other actors.
- The horse head in the bed was completely real. During rehearsals, the crew used a fake head, but the director wanted a more authentic reaction from actor John Marley. Therefore, he sourced a real head from a dog-food factory, and the actor’s terrified screams were genuine.
- The word mafia never appears in the first movie. A real-life Italian-American league pressured the producers to remove the term from the script. Thus, the characters use words like family or business to describe their criminal activities instead.
- Al Pacino was nearly fired during the first week of filming The Godfather. Studio executives thought his performance was too quiet and boring. However, they changed their minds after seeing the intense restaurant scene where Michael kills Sollozzo and McCluskey.
- James Caan wore 127 blood-filled explosive squibs for his death scene. This sequence at the toll booth was the most expensive shot in the entire movie. It cost over 100,000 dollars to set up and required more than 200 pre-drilled holes in the car.
- Oranges always signal a coming death or tragedy. Whenever you see the fruit on screen, a character usually dies or suffers a near-fatal attack shortly after. This visual theme became one of the most famous easter eggs in film history.
- Robert De Niro originally auditioned for the role of Sonny Corleone. While he did not get that part, the director remembered his talent for the sequel. As a result, De Niro won an Oscar for playing the younger version of Vito Corleone.
- The legendary line about the cannoli was improvised. The script only told actor Richard Castellano to leave the gun behind. However, he added the part about the pastry because a previous scene mentioned his character’s wife wanted dessert.
- Marlon Brando used a dental plumper to create his bulldog jaw. For his audition, he stuffed his cheeks with cotton wool to change his facial shape. Later, a dentist created a custom prosthetic that the actor wore throughout the entire production.
- The Godfather Part II was the first sequel to win Best Picture. Before this achievement, Hollywood viewed sequels as cheap cash-ins rather than serious art. This victory changed how the industry approached long-form storytelling.
- Sofia Coppola appears in all three movies of the trilogy. She played the infant baby in the first film, an immigrant child in the second, and Michael’s daughter in the third. Her final role drew significant criticism for her acting abilities.
- The actors held family dinners in character to build chemistry. The director organized these meals so the cast could establish their relationships naturally. They had to stay in character while eating spaghetti and drinking wine together.
- Sylvester Stallone auditioned for several minor roles in The Godfather but was rejected. He tried out for the parts of Paulie Gatto and Carlo Rizzi before he became a star. Ironically, he later became one of the biggest names in Hollywood alongside the cast.
- Marlon Brando refused his Academy Award for Best Actor. He sent an activist named Sacheen Littlefeather to the ceremony in his place. She gave a speech protesting the treatment of Native Americans in film instead of taking the trophy.
