Factual error: When Hooker comes out of the diner there is a billboard advertisement to the right. It is for Ezra Brooks bourbon. Ezra Brooks brand wasn't created until 1957.
Factual error: Near the end of the chase, when Buddy is ramming the bad guys' car, the scene is supposed to take place in New Jersey as they just crossed the George Washington Bridge. However we see a road sign for NY 100/133, indicating they are back in New York state on the Taconic State Parkway.
Factual error: While Sgt Howie (dressed as Punch) is being chased by the women, you can see autumn leaves on the grass, though the story is set on the 1st of May.
Factual error: Buford drives into his yard on Christmas morning and there are green leaves on the trees. Not in Tennessee, in winter!
Factual error: The kid is wearing a Texas Rangers baseball cap. The Rangers didn't come to Texas until 1972.
Factual error: The henchman with the prosthetic arm bends Bond's gun. It would require something in the range of 1000 pounds of pressure to bend a gun like that. It would be impossible for anyone to generate that much pressure since the arm is driven only by human muscle. (00:24:50)
Factual error: During the flashback explaining what happened to Su Lin she has an ugly bruise on her face less than a minute after being hit. Bruises usually take at least a few hours to develop like that.
Factual error: Facing the mysterious fighter from Africa in his apartment, Shaft shoots him twice with no results. It is later revealed that he was wearing a bulletproof vest, but it's the overpowered movie kind: the guy doesn't suffer from the impact of the bullet in the slightest. Not just that: there's not a single hole or mark on his white robe in that scene. (00:08:40)
Factual error: In the second chase scene (when Gator is blocking for Roy) it shows Gator turning on to Laurel street then entering into the parking lot and the storage area of a lumberyard (where the lumber falls on the state police car). Laurel St. is in N. Little Rock and the lumberyard is the old Wrape Stave lumber yard (also known as Dixie Culvert) in E. Sixth street in Little Rock.
Factual error: When the pimp murders the hooker in the taxi, he is said to have forced drain cleaner down her throat. However, he uses an aerosol can. You can even hear the metal ball shaking inside of it several times. In the 1970s, drain cleaner did come in metal cans, but what he is using is a spray can of some kind, which drain cleaner did not come in. It is always in liquid form to pour down a drain, spray would not release enough.
