Corrected entry: Michael is accused of killing the heads of the 5 families in 1951, but during that scene in the movie, he leaves the church in a 1954 Packard. (02:35:10)
Corrected entry: When Brando is being taken home from the hospital there are mercury-vapor street lamps visible in the area. They were not in use in 1946 or so.
Corrected entry: In the beginning, Marlon Brando looks outside his window when they bring the wedding cake in. On the left side in the crowd there is Sonny, who is supposed to be in the room with the Godfather. You can identify him by the white flower in his lapel and by his bride sister who walks up to him from behind. (00:23:50)
Corrected entry: The first time we see Jack Woltz's mansion, there is a large TV antenna on the left side of the roof. Surely television had not been invented yet, and it is not a radio antenna. The next time we see the mansion, when Woltz is about to awaken to a surprise in his bed, the antenna is no longer visible. It was assumed that the error was realized and the antenna was removed by the filmmakers.
Corrected entry: An arithmetic issue. Tom Hagen suggests to Sonny the the "Five Families" would "come after" him if they hit a police captain (which will be Capt. McCluskey). Since the Corleones are one of the five families, that would leave only four others to oppose them.
Corrected entry: When Sonny arrives at the toll booth there is a toll booth operator taking money from the other cars. When Sonny drives up, the toll booth operator ducks down and then disappears, never to be seen again once the hit is over-he simply vanishes from the scene altogether.
Corrected entry: The infamous horse whose head is found in the bed of his owner, bloodied and mangled, has a white spot on it before it is chopped off. Later the white spot is gone.
Corrected entry: When Michael allows Kate to ask him just 1 question about his business, he walks up to his desk and places both hands on the desk. When the camera angle changes to a rear view of Michael he is seen just standing straight up, when it changes again to a front view he is leaned over with his hands back on the desk.
Corrected entry: Luca Brasi goes to meet the Tattaglia family and Sollozzo, to pretend he would like to defect. Before they garrot him, Tattaglia stabs a knife into Brasi's left hand. Halfway through his death throes a wider shot reveals the knife in his right hand. The sequence concludes with Brasi slumped on the floor with his knife-impaled left hand still on the counter.
Corrected entry: The scene where Sonny is shot at the toll booth is supposed to take place in the late 1940's. However, as Sonny is driving up to the toll booth, he is listening to a baseball game on the radio that took place on October 3, 1951. In that game, Bobby Thompson hit a home run off Ralph Branca as the Giants beat the Dodgers and won the pennant. (01:52:25)
Corrected entry: Tattaglia tells Tom that the Godfather survived in spite of having been shot five times. But even if the first two bullets missed while he was running we can tell from the way the hitmen aimed at him that he is hit close range at least nine times while he is leaning against his car.
