Visible crew/equipment: In the shootemup scene at the hangar, at the beginning of the film, Castor Troy shoots an agent in the stomach and the agent flies back - you can see the wire pulling him backwards.

Continuity: At the end of the film, when Nicolas Cage and John Travolta are lying next to each other in the ambulance, there is no blood on Travolta's shirt collar and suddenly, between shots, the collar is covered in blood.

Visible crew/equipment: At the Walsh Institute, after Sean gives his ring to Tito, when the stainless steal sliding door closes, the camera and a crew member, or likely the director, is seen looking behind the camera lens in the glass window reflection.

Continuity: When Sean and Tito first drive the Hummer onto the runway, the jet is a mere short distance away, coming towards them. In the following shots, the distance between the Hummer and the jet has increased tremendously, for the ensuing drama to unfold.

Continuity: On the chopper, when Sean Archer points his gun out the window, in the shot facing him the window to his right is a double slide type. In the next shot, from inside the chopper, his arm is through a single window that flips down.

Continuity: When Cage and Dubov are making their escape, Dubov falls over the rail and Cage catches his gun then tries to save him. In the last shot before Dubov falls, Cage is holding on to the very last tip of the gun, but in the wide shot he is holding a lot more of the barrel.

Visible crew/equipment: When Sean (as Castor Troy) is doing the ‘water skiing’ thing, trying to hang on to the speedboat’s chain, in the close-up the harness he wears is visible under his wet white shirt.

Continuity: On the speedboat, when the anchor comes loose from the boat's bow it takes with it a large chunk of metal and leaves a gaping hole, but next shot, as the anchor falls to the water, the huge hole is gone leaving only the bullet holes on the surface.

Revealing: In the big speedboat scene near the end, when Cage is hanging off the side of the boat the stunt double is obvious in wide shots, where the entire boat is visible from above. He has big long sideburns, which are in stark contrast to Cage's short hair, visible in closer shots. At various other points in the movie, stunt doubles appear of much different physical builds than the two actors, with markedly different hair colours, and I seem to recall that at least one of them had facial hair.

Visible crew/equipment: At the L.A. Convention Center, just before Castor Troy (as Sean Archer) disarms the bomb, there are a few shots of all the extras evacuating the area. In the interior shot, that looks out through the glass doors onto the street, the tracking crane arm with a seated camera operator and camera on its platform is visible as it shoots an exterior crane shot of all the extras, which was seen among the previous shots.

Revealing: At the boat scene when Archer is holding on to the red boat and is skiing on the side, you can clearly see the waterproof boots he is wearing.

Visible crew/equipment: When Sean first visits the Walsh Institute, he, Dr. Miller and Dr. Walsh walk in front of the circular glass window to view the ear reconstruction. In the next shot facing them, the reflection of a boom operator holding the boom pole is visible on the glass in front of Dr. Miller and Sean.

Visible crew/equipment: On the runway, two shots after Castor Troy says, “This is a big gun. Fly the f*ing plane,” there is a side shot of the Hummer. As the camera pans in closer, the reflection of a crew member on the filming vehicle, which moves beside the Hummer, becomes visible at the Hummer’s back end, just before it cuts away.

Visible crew/equipment: When the red boat has hit the barrier and Castor Troy and Archer fly through the air, you can see a wire attached to the front of the boat just for a split second, then when it falls in the water and explodes.

Continuity: When Sean Archer is flying the helicopter to keep the plane from taking off, Castor Troy shoots the helicopter windshield three times, but there are four bullet marks.

Continuity: After the second speedboat explodes, when Sean (as Castor Troy) pulls the speargun trigger, Castor (as Sean Archer) grabs the spear shaft before it can unload. As he grips the gun, the problem is that in some shots the slings are still loaded, but in other shots they are not.

Continuity: After Castor Troy is told they are being followed on the runway, there is a close-up of Sean Archer and Tito in the Hummer and the rear view mirror is gone. It is back in all the other shots.

Visible crew/equipment: During the raid at Dietrich’s, when Sean (as Castor Troy) hangs on to the chain then grabs hold of Pollux, in the close-up Pollux’s safety wire is visible in front of him. (This is not Sean’s safety wire, as seen in the following shots.)

Revealing: When the FBI agent asks Archer , "Sir, why are you upset? Its only Pollux Troy", you can see discoloration of a lump on his forehead which is makeup covering the blood pack for when Archer shoots him right after.

Factual error: In the hangar scene when Castor and Archer point their guns at each other, if Castor's gun was really empty the slide would be locked back.
