Continuity mistake: After Duke unlocks the gate, when the Mayflower moving truck is driven out of the lot there's a built-in tow hitch at the back of the truck, but when it pulls into the apartment building the tow hitch is gone - the back bumper is one solid piece.
Continuity mistake: When the Mayflower moving truck leaves the lot and picks up the crew there's no license plate on the front bumper when Tommy gets in, but when the truck crosses Broadway suddenly there's a license plate on the bumper, and then it vanishes. Additionally, when the van's stowed away in the truck it doesn't have an antenna on the hood and "256-245" is the van's license plate number, but after the heist there's an antenna and the van's plate number is "C47-618".
Continuity mistake: After Mrs. Longene eggs on Socks to kill her husband for not revealing the safe's combination to save her, it cuts to the first man on Everson's team rappelling without gloves - the gloves are in his back pocket, and in the next shot he's wearing the gloves. Then the next cop to rappel across is not Everson, but in the close-up it's Everson reacting to the rope burns on his hands as if he had just crossed.
Continuity mistake: After Duke gets frustrated that Mr. Longene still hasn't given him the combination to the safe he asks for Socks, and when it cuts to Everson and his team rappelling to another building, as Everson climbs over the railing his shoes have changed to climbing boots and his badge has vanished.
