Continuity mistake: Carl's cop car has the licence plate "G2298" which is printed thinly on the licence plate. Then, when the vine wraps around his car, and bends it in two, the licence plate is now "CFJB95", printed very boldly on the plate. The words "POLICE 004" also differ, as does the bumper and the lights. Totally new car, methinks... (01:14:55)
Visible crew/equipment: When Verbal drops the Zippo lighter in the police office, Chazz Palminteri leans down to pick it up. When he leans down out of frame, there are 2 "C-stands" visible in the background. These shiny, adjustable stands are general-purpose utility holders on a movie set, used to position lights and light control material for a setup (i.e. flags, scrims, diffusion, etc).
Revealing mistake: When the computer is being hacked and the password and/or code for the database is shown on the screen, most of the display is for an Autodesk printer driver. (01:39:00)
Revealing mistake: Whilst in Q's workshop, Bond places his envelope on Q's X-Ray Document scanner. If you pay close attention to the screen (it's easy to notice anyway) his flight ticket has got VOID written on it 4 times... (00:51:54)
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)
Continuity mistake: Towards the end, when Bruce Willis notices the writing on the aspirin bottle, he leaves it in the phone booth and the camera jumps towards it a couple of times. In the first shot the writing's almost vertical, but in the following shots it's at a definite angle. (01:48:35)
Visible crew/equipment: In the drive-in shootout scene, the camera and crew are visible in the rear view mirror in the cab of the white Dodge pickup fleeing De Niro and Kilmer.
Continuity mistake: When the fat sailor gets on the bus, Dougherty is adjusting his hat with his left hand. In the very next shot he has his right hand on his hat. (00:11:45)
Continuity mistake: As "Sandman" is making its bombing run, the bomb door is opened - in the next side angle shot of the plane, the door is shut again. (01:56:00)
Revealing mistake: When the plane first lands at Bangor airport, the words 'American Pride' on the plane are reversed, like they are reflected in a mirror in one shot as its wheels hits the runway. (00:50:55)
Continuity mistake: When Sandra Bullock is looking on the screen at an IP address, we cut from her and the monitor to just the monitor and the IP address changes.
Continuity mistake: Two-Face and the Riddler are in Two-Face's lair; the Riddler has just said, "Then I taught my doggie a new trick; how to map the human mind." In the establishing shot, the tube is in left hand; after the cut, it's in his right hand.
Continuity mistake: In the parking lot scene we see Tommy get thrown through what appears to be plasterboard. When he goes through it leaves a big chunk still attached in a triangle shape. Camera cuts and what remains has changed and the triangle piece is not to be seen. (00:23:10)
Visible crew/equipment: When Salma Hayek is tossing the bullet she has just removed from Antonio Bandaras's shoulder, you can see the reflection of Robert Rodriguez holding the film camera on the metal dish.
Continuity mistake: Miguel Bain escapes from a police car by snapping the neck of the cop who was driving. The wide shot shows however that the cop is still very much alive and driving. (00:15:32)
Continuity mistake: When Lucifer confronts Thomas, Lucifer forcefully pulls him closer and puts his right hand on his chest, but the close-up shows that his hand is under Thomas' arm. (01:21:20)
Continuity mistake: When Wesley is driving his motorbike down the subway stairs to catch the money train, we see a couple on the stairs who both move to the side (backs against the wall), but in the next shot with the camera facing up the stairs, the couple have disappeared. (01:19:10)
