When Henry takes Karen to the Copa, they enter through a service door and through a labyrinth of passageways until they finally emerge in the dining room. As the camera follows them on their journey, a modern fire extinguisher is near the kitchen area. At the time, most fire extinguishers were either the dry powder, push-handle type (similar to old insect sprays) or gravity-fed liquid extinguishers that worked by turning the unit upside down and directing the nozzle.

When Henry and Karen are on their date at the Copa, they are drinking champagne from large flute glasses. While a 4oz flute that had been introduced in the 1930s, Henry and Karen should have been drinking from coupe style glasses as large flutes did not become popular until the mid-seventies.
In the footnotes, it is noted that "In 1989, Henry and Karen Hill separated after 25 years of marriage," meaning that they were married in 1964. However, in a scene from before their marriage, we see a 1966 Corvette parked across from Karen's mother's house.

Paul Cicero's brother In the film, played by Frank DiLeo, Is billed as "Tuddy Cicero" - this Is an error as the name should be written "Tutti Cicero" (Tutti Is Italian for "all" or "everything", as In Tutti Frutti). The error perhaps occurred as the two words sound almost Identical In American English.
Paul Cicero's brother in the film, played by Frank DiLeo, is billed as "Tuddy Cicero" - his first name should have been Turi and not Tuddy, a possible error due to the mispronunciation of the original Sicilian name. In Sicilian the name Salvatore is often abbreviated as "Turridu" or even further to simply "Turi". Turi Cicero makes sense but Tuddy doesn't. Also there is no letter Y in the Italian language.

The mob men grab Henry's mailman leaving work from a post office named "Pitkin Ave Station, Queens, N.Y.". Henry lives in East New York, Brooklyn, which would be in a different zip code.
When Maury's address is shown in his TV ad, not only is the number not hyphenated (as all Queens addresses are) are, but address should include the neighborhood's name, not simply "Queens, NY".

When Henry picks up his brother at the hospital after nearly being in an accident, the doctor gives him an orange tablet which is suppose to Valium 10mg but Valium 10mg tablets are blue. Valium 5mg tablets are yellow; therefore, it could not have been two 5mg tablets.

After Tommy shoots Spider Jimmy grabs the gun by the barrel but doesn't react to the heat from the gun generated from the shot.

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.

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.
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.
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.
When Jimmy is crying about Tommy getting whacked, a crew member is reflected in the phone booth.
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.
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.
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.
After Tommy De Vito kills Morrie from behind in the car, Morrie clearly breathes on the left edge of the screen.
