Ordell insists that .45 pistols have become popular because The Killer (Yun-Fat Chow) used a .45. In fact, Yun-Fat Chow wields a 9mm Beretta throughout The Killer (1989). The only .45 that appears anywhere in the movie is held by a Triad.
When Jackie pays for the new suit, the cashier doesn't count the wad of bills that Jackie hands over. This goof occurs again when this scene is repeated from a different character's point of view although at least, this ensures continuity.
After Ray shoots someone, he checks their pulse with his thumb. Correct procedure is to use the first and second finger to take someone's pulse, as the thumb has it's own (weak) pulse and thus cannot give an accurate result. This is fairly basic knowledge that someone in his position should know.
In the closing scene Max tells Jackie, "I'm 56 years old," yet when he shows her his ID card earlier in the film his date of birth is listed as 3/15/48. This would make him 47 at the time the film is set (1995).
While putting the money in her bag in the airplane bathroom, Jackie drops numerous items on the floor. She doesn't pick them up, yet when the camera goes again to an overhead shot, the items on the floor are gone.
When Simone is leaving the mall Max Cherry writes down the license number of her car. The number is 3L60314, which is a number, then a letter, then 5 more numbers. This sequence is used in California on Commercial plates found on Pick-up trucks and Medium and Heavy Duty trucks, not privately owned cars.
Del Amo Fashion Center is listed during the film as the largest indoor shopping center in the world. At the time of production, that distinction belonged to the West Edmonton Mall in Edmonton, Alberta, Canada.
The first time we see Jackie pointing to the fitting rooms, she uses her right hand. The second time, she uses her left. Quentin Tarantino frequently uses this kind of inconsistency in "replayed" scenes in his films, to show the same scene from many different perspectives.
Traffic suddenly disappears when Ordell shoots Louis inside the van, and the parked cars keep changing. Also, two men seen hanging out on the sidewalk during the close-ups on Ordell are gone in the wider shots.
: When Ordell and Max go to his office at the end of the movie to see Jackie, Ordell has the gun in his hand when he first walks in with Max. When he walks through the doorway towards Jackie, you can clearly see he has nothing in his hands, but after Ray shoots him, he kicks the gun away from Ordell's hand.
When Jackie and Ray Nicolette are standing over Ordell's body, there is a shot from Ordell's point of view, as well as a shot of Ordell from above. The position of Jackie (left) and Ray's (right) faces and their shoes switch sides between shots.
