• Anachronisms

    When Lois makes the call that dooms Henry, her Trimline phone has the 1984 AT&T logo. The scene is set in 1980.

  • Audio/visual unsynchronised

    When Tommy kills Stacks, the silencer is heard three times after he shoots Stacks in the head. During the slow-motion replay, Tommy shoots Stacks 5 times in the back, 2 times more than in the previous scene.

  • Continuity

    A title card dates the Billy Batts murder as June 11, 1970. When they go to dig up the grave, Henry says "it's been six months." It should be winter in New York, but the boys are in short sleeves and Henry's kids are going to the beach the next day.

  • Continuity

    When Jimmy finds out Tommy has been "whacked", check the car window in the background. When Jimmy goes to the car it is open, but when he pushes over the phone booth, it's closed.

  • Continuity

    When Tommy kills Stacks, Carbone stands in the doorway and watches Tommy shoot Stacks three more times after shooting him once in the head. In the slow motion alternate view, Carbone is not in the doorway, and Tommy shoots Stacks five more times instead of three.

  • Continuity

    When Jimmy opens up the trunk of the car and finds Billy Batts still alive, Tommy pulls out a large butcher knife and plunges it into Batts almost to the hilt several times. He then stands watching while Jimmy empties his gun into Batts' body. There is no blood on either Tommy's hands or the knife.

  • Continuity

    After Tommy breaks a bottle over the restaurant owner's head, his jacket changes from clean and dry to splashed and back between shots.

  • Continuity

    When Jimmy strangles Morrie with the telephone cord, Morrie's grip on the phone changes between shots.

  • Continuity

    Every scene coming to or going from Karen's home, regardless of passage of time, (i.e. the neighbor rough-up, Henry leaving) was obviously shot in the spring, with all trees, shrubs in the same state of bloom. In the latest shot, the hot pink almond or dogwood tree was faded.

  • Continuity

    Immediately before Tommy shoots Spider, Jimmy's hands are up as he says, "What's the world coming to?" In the next shot, which is clearly meant to be seamless with the previous shot, as Tommy whips out his pistol, Jimmy's hands are suddenly back together in front of him counting money.

  • Continuity

    When narrating, Henry says that Tommy was shot in the face "so his mother couldn't give him an open casket at the funeral." Earlier, however, we see Tommy is shot in the back of the head. A shot to the face would have been better, as it would only present the mortician with a small entry wound that he could patch up easily; the back of the head, however, would be blown away (but unseen in a casket setting). Conversely, a shot to the back of the head would obliterate the face, necessitating a closed-casket funeral.

  • Crew or equipment visible

    When Jimmy is crying about Tommy getting whacked, a crew member is reflected in the phone booth.

  • Factual errors

    When Tommy shoots Spider in the foot, Tommy fires a total of seven shots from a S&W Model 36 5-shot revolver without reloading.

  • Incorrectly regarded as goofs

    When Tommy takes out Stacks, he says, "You'd be late to your own funeral" as he puts the gun to the back of Stacks' head. When they show Tommy in slow motion, he doesn't say anything. Tommy shoots him once in the head, then changes positions before shooting him again. In slow-mo, we don't see the first shot, only the latter ones.

  • Revealing mistakes

    When Tommy pulls out the knife to stab Billy Bats, you can see when the light hits it that it is a retractable prop knife.

  • Revealing mistakes

    After Tommy De Vito kills Morrie from behind in the car, Morrie clearly breathes on the left edge of the screen.
