Other mistake: When Katya is told that Frank was spotted in Red Square, she tells the soldier (in the English subtitles) to call out the Army - but she says, in Russian, something about Spetznaz - which Is Special Forces, not Army.
Other mistake: In the hospital, Mullins says she took the bullets out when she threatened to shoot Julian in the groin. However, we saw her leave one bullet in.
Other mistake: The Rolls-Royce at Watkins Glen, and the Mini in England, have the same English license plate.
Other mistake: When Ray attempts his first escape, he emerges from the front right side of the fire engine. When he explains how he did it, he appears too far in front of the fire engine to make it look like he was underneath it. (01:07:25 - 02:13:40)
Other mistake: When Stig shoots the helo and kills the co-pilot it still crashes. He killed the co-pilot, the pilot sits on the right side. (01:36:30)
Other mistake: Throughout the film, you can frequently see many people's faces blurred, phone numbers blurred, store-fronts blurred, etc. This is because the production could not afford the rights to show these people, places and things, and simply blurred them out.
Other mistake: Ten minutes into the movie, during the credits one character is presented as "Cheno", but in the end credits he's "Chino". (00:10:35)
Other mistake: When the title card "FLYING MONKEYS" appears on screen, during the opening fly-over shot, if you look near the bottom right of the screen you can see something briefly move into, then out of, shot. (00:02:28)
Other mistake: After the Enterprise is disabled by the Vengeance and falls out of warp, Kirk and Spock have a discussion in one of the corridors about letting Khan help incapacitate the attacking ship. Watch behind them. The ship is running under Red, but the crew members are walking past them calmly, some even watching their conversation as they pass! Not really Red Alert protocol... In fact, through all of this, only one crewman runs past in the entire sequence.
