Continuity mistake: Right before they rob the police car, a Boeing 747 (four engines) is seen in shots of the plane coming into land. When the plane is shown from behind, it is a Boeing 767, with only two engines and fewer main landing gears. (00:30:10)
Other mistake: When Somerset goes back to the man's house alone, he cuts a sticker on the door with his switch-blade to get in. The first error is the sticker is on the inside and it says "Keep Out." The best part about it is the door opens inward. How did they put the sticker on the inside and then exit? (00:20:45)
Visible crew/equipment: When Neil (De Niro) breaks into Van Zant's apartment and shoots him, watch as Van Zandt flies backward. You can see a wire running up through the bottom of his sweat pants.
Continuity mistake: In the scene where Max cuts down the bridge and the real scout master dives after Max cuts it down, in the backround in the top left corner you can see the scout master get up, then when the camera goes to the scout master, he gets up again.
Continuity mistake: In the last scene on the roof when Holly Hunter shoots the serial killer, he falls backwards. The gun is in his left hand and the path is next to his left hand. The camera then goes to the rear of Sigourney as she walks toward Holly. Only now the serial killer is on the other side of the path and the left hand holding the gun is no longer next to the path.
Continuity mistake: When Selena is leaving on the ferry near the end, and Detective John Mackey pulls up and watches her drifting away, as he gets out of the car the windsheild wipers stop moving. In the next behind shot of him standing at the dock edge, watching, they are back on again. (01:43:05)Hamster
Continuity mistake: This is the car chase scene, where Ralph Fiennes and Angela Bassett are in a limo being chased by two bad cops in a pickup. Early in the scene, you have the view from inside the pickup when it rams the limo from the rear passenger side, and you can clearly see bullet holes in the glass and rear of the limo (no weapons fired yet). Then a few seconds later in the scene, you can see the rear of the limo with no damage. Moments later, you see one of the cops firing an automatic weapon, and subsequently witnessing the holes being made in the limo.
Factual error: The movie is set in 1948. When Easy first visits Albright about the job, Albright throws some $20 bills down in front of him. The top bill bears the signature of Treasury Secretary Nicholas F. Brady, which appeared on paper currency from 1988 to 1993.
