Continuity mistake: When they're in the car, after collecting the money, Julianne Moore holds up the disk, and we can see she's holding the metal flap open, so we can see the actual disk. Then the camera cuts to the other side, and the cover's closed. Cuts back to the original shot, and the cover's now closed on that side too.
Continuity mistake: Near the end, when the Russian assassin (which "Robert" thought he killed years earlier) comes into the room, he sets the case down, takes off his sunglasses with his left hand and kicks "Miguel" to see if he's dead. Just before the kick, the camera changes angle and we see the sunglasses on the case instead of in the Russian's hand.
Continuity mistake: After Banderas loses his rifle in the taxi, Stallone stops the car and then sees the cops. As he is reversing the car, it shows the front end of the car and both of them looking behind. You can see, however, two problems. Firstly the large cracks and bullet mark on the barrier window in the cab are completely gone and there seems to be large damage and cracking to the back window. When the shot changes to Banderas looking out the back, there are just a few drops of rain on the back window, and it's easy to see through. You can also see the cracks and bullet mark on the barrier window return.
Continuity mistake: In the bank, Rath offers all his money to Bain to walk away. As he is saying, "But you won't do that way", he is gesturing with his left hand in the air. As Bain says "No", Rath's hand is still in the same position. Cut to a close-up of Rath, and he is suddenly holding his hands together, and folded in front of him. New angle change, and Rath's left hand is back to the first position, with his right hand resting on his chair. There was no time for him to move his hands between shots.
Continuity mistake: When Rath and Bain are talking in the bank, Rath asks about Bain's sunglasses. In the close-up of Rath, he is holding his hands together in front of his face, right above left, with his right index and middle fingers on top of his left hand. Cut to a shot from behind him, and now his hands are suddenly folded, with fingers interlocking.
Continuity mistake: When Rath and Elektra are in the car talking about the new price they'll put on the disc, just as Elektra says, "Sounds like a mid-life crisis to me", Rath's left arm comes into the foreground, being briefly rested on her seat before sliding off and down. Cut to a close-up of Rath's face, and he is suddenly touching his face with his left hand, with no time to move his hand between shots.
