Continuity: When C is rolling the dice for Sonny, Sonny sends Coffeecake to the bathroom. While Sonny's men are dragging him there, in the "3-frame" shot with all Sonny's men "C" isn't there any more, and in the shot that follows, he reappears.

Factual error: When Sonny walks C down the street and explains that he rid himself of someone for a small price, you see a one-way sign with a triangle edge. These are only used in California.

Continuity: When Calogero is sitting on his stoop before Phil gives him free peaches, he has a ball in his hand. In the next shot the ball disappears.

Factual error: When Calogero is 9 at the beginning of the movie it is 1960, the lower baseball on his jacket says METS. The Mets where not a team until 1962.

Visible crew/equipment: Stunt men are visible in the car just before it explodes from the cocktail grenades.

Factual error: It's supposed to be 1960 but the parking meters on the street where "C" lives are the new kind with the slits for coins rather than the slots. These parking meters did not exist until 1973.

Continuity: In the scene near the end of the film where C is alone at Sonny's funeral and Joe Pesci walks in, the rosary beads on the dead body's hands change position several times.

Continuity: When Jane and Calogero first meet in front of the school, a couple walk down the stairs and in the next shot the same couple are back on top of the stairs.

Factual error: Although the movie neighborhood is meant to be 187th Street and Belmont Avenue, a NYC bus (from the old Surface Transportation System) is shown running along that street, where none ever did. In at least one scene, the sign on the bus indicates it's the 12 bus, Fordham Road from Sedgwick Avenue to City Island. Fordham Road was three blocks north of 187th Street, and never had its own bus route.

Deliberate "mistake": When "C" and Jane are walking home together and Jane pronounces "C's" entire name she says his first name Calogero as well as his last name Anello but he never told her his last name he only told her his first name when they met.

Continuity: In the scene where Sonny and his crew catch C and his friends trying to buy guns on the corner, you can see Jimmy Whispers look directly into the camera and then quickly look away as his crew is approaching C and about to beat up the gun dealer.

Revealing: During several scenes, the street lamps are the mercury vapor type which were not used in the 1960's.

Visible crew/equipment: During the beginning credits when the guys are playing stickball, you will notice the shadow of the camera and microphone on the building.

Continuity: When C is fixing his bike on the sidewalk, if you look close you can see that his hands are black from the grease on his bike chain. When he goes into meet Sonny, both of his hands are clean.

Factual error: A scene in front of Aqueduct Racetrack shows a fire hydrant with security caps that weren't invented until the mid '80s, approximately 17 years after the film is set.

Factual error: When the detectives are first bringing Colagero out to the street after the shooting by Sonny, an electronic siren can be heard winding down and cutting off mid-tone. Only motor-driven sirens were available on emergency vehicles during this period, and when they were turned off, they simply wound down.

Continuity: In the scene where Sonny is letting a young C shoot craps and tells Frank "Coffee Cake" to go to the bathroom because he doesn't want C looking at him when he rolls the dice. Coffee Cake is wearing a beige short-sleeve shirt and even though he is shown in the bathroom in the next scene when C is about to roll the dice, Coffee Cake's beige shirt and arms are shown at the end of the crap aisle as if he was never sent to the bathroom in the first place.

Revealing: In the scene where C is rolling dice with all the guys, Jojo the Whale keeps trying to get a better view and keeps breathing on Sonny which gets Sonny mad. In one of those shots, you can see Jojo look up at someone in the production crew, behind the camera view and as if on cue, start to get close to Sonny and get him mad again. There is nothing behind the camera that's shooting the shot except a wall.

Continuity: At the end of the film when Joe Pesci stops in at Sonny's funeral, he begins to talk with C. You can see the scar on Joe Pesci's forehead. Between shots, the scar disappears, or lightens up, as if it were not there.

Factual error: The red and black destination signs shown on the GM old-look busses during the 1960 scenes weren't used until the late-'70s. The early signs were simply black and white.
