Audio problem: When Sonny is punching Carlo under the spraying fire hydrant, he misses an audible punch by at least six inches.

Revealing: At the Godfather's funeral, as Al Pacino stands up, you can see a reflection of his mother over on the right of the screen. It's clear in the widescreen video. The same happens when he sits down again.

Continuity: When Sonny is shot at the toll booth the front windshield is torn apart by bullets yet when the bodyguards arrive thirty seconds later, the windshield is intact.

Continuity: After Michael shoots Sollozzo in the head, he turns to McCluskey and shoots him in the throat and then in the head. But in the long shot, before he shoots McCluskey in the head, you already can see the hole in the forehead.

Continuity: When Tom Hagen is meeting with Jack Woltz, the server fills Tom's wine glass twice within a split second.

Factual error: In the scene where all the heads of families meet shortly after Sonny's death, there is an exterior shot of a large grey-brick building with an American flag hanging from it. If you look carefully, the flag is a current flag with 50 stars, with alternating rows of indented stars. But, the scene is takes place circa late 1940's when there were only 48 states and all the rows of stars were even. (By the way, the flag inside the meeting room is the correct one.)

Revealing: When Moe Greene is shot through his right eye, the eyeglass is cracked, but has no hole where the bullet penetrated the glass.

Continuity: When Michael and Kay are eating lasagne during the wedding, Kay is smoking a cigarette. But depending on the shot, that cigarette disappears from her hand, then reappears.

Revealing: When Vito Corleone is walking Johnny Fontane out of his office, he opens the door and you can see an extra walk by and stop, look at the camera and actors, and back up out of the shot. (Mentioned on the commentary).

Continuity: When they're all having a meal in Sicily, watch behind Appollonia. Two people, one in red, one in white, walk past in the same direction twice - once in a wide shot, and once in a close-up of Appollonia.

Audio problem: When Carlo gets strangled in the car and kicks the windshield the sound of breaking glass can be heard before it actually happens.

Continuity: When Tessio delivers the bulletproof vest and the fish, Sonny's hands are in one position (one below, one on top of the parcel), a fraction of a second later they are in a very different position (both on top, unwrapping). The parcel is half open while Tessio is carrying it but fully closed when he puts it on Sonny's lap.

Continuity: Before Paulie is shot, Clemenza gets out of the car to relieve himself and walks only a few steps away from the car. As Clemenza hears the gunshot, he looks back at the car to see Paulie slumped over the steering wheel, and the car is a much greater distance away, than just the few feet he had walked away from it. As Clemenza walks back to the car, it again takes him only a mere few steps.

Revealing: When Michael and Fredo arrive at the Las Vegas hotel Fredo's actor is replaced by a double who doesn't resemble him even remotely.

Continuity: In the first scene the undertaker Bonasera asks the Godfather for help. When the Godfather gets up from his desk the rose in his lapel is either fresh and straight or slightly wilted and bent in alternating shots. Also later in the wedding scene this rose keeps recovering from intermittent spells of weakness.

Continuity: When Marlon Brando is gunned down at the fruit stand, he drops the bag of fruit he just bought. However, when he's collapsing against the car, the bag of fruit is now on the hood of the car.

Continuity: When the 'baker' is meeting with Don Corleone about keeping his son in the country, he's holding a 'shot glass' in one hand, and a thin cigar in the other. When he reaches out to clasp the Don's hands in gratitude, the items are GONE. A split second later, they're BACK.

Other: After Sonny is shot on the causeway, there are a very large number of bullet exit holes visible on the sides of the tollbooths, which could only have been made if the gunmen shot through the walls (not the windows) of the buildings from the inside. This is common in movies. In real life, bullet entry holes in wood appear as small black dots, not the more dramatic-looking splintered gashes made on the other side of the wood as the bullet exits.

Continuity: When Clemenza knocks at the door Sonny gets a gun from a drawer and puts it in his belt. When he pushes Clemenza the gun disappears, but it's back a moment later. As the shot where the gun disappears is uncut the gun must have slipped down his pants.

Continuity: When Diane Keaton and Al Pacino have dinner, he gets up, puts on his coat and sits down again. Now watch Diane Keaton's glass: When the camera's on Al Pacino she's holding the stem, but when the camera's on her she's holding the body of the glass. Another mistake is that at the end of the scene the amount of wine in her glass suddenly doubles.
