Continuity mistake: Glenn Close's outfit changes four times during the same courtroom scene, while she is giving her opening statement in front of the jury.
Continuity mistake: After a long car chase about mid-way through the film, the camera pans over the highway littered with smashed cars and hundreds of cars piled up. In the middle of this, you see a van painted a little like the Partridge Family bus....definately a one of a kind van. Then you see footage of the car which escaped the chase going down an empty side street and passes the same van. No way there are two vans like this one.
Continuity mistake: After Pola Ivanova sneaks out of the baths, she climbs into the car with General Gogol, who can be seen to be a double and not Walter Gotell. (01:07:20)
Continuity mistake: After Manny's fingers get crunched between the cars, blood sprays on his face. In the next couple of scenes there is hardly any there. Also, when the prison warden get sprayed with the fire extinquisher he is cleaned up in the following shots.
Factual error: When Rambo plays possum then suddenly takes out the Russian officer's Hind Helicopter he uses an M72A2 light anti-tank weapon (LAW). When fired, the M72A2 has a back blast that can kill out to 100 feet, which means he would have either blown up his own helicopter or killed all the MIA's he had rescued...
Continuity mistake: When Harrison Ford confronts (and beats up) the tourists, there are a number of close-up shots of the people in the first wagon, including one where Viggo Mortensen leans forward and tells the driver to do nothing, even though he is being provoked. In all these close ups, Mortensen is bare-headed. When the shot changes to Ford's perspective, from the cart behind, we see one of the tourists grab a straw hat from Mortensen's head. The hat has appeared out of nowhere in a split second. There is a child with a straw hat behind Mortensen, but the hat stays on his head in both shots. (01:22:50)
Plot hole: When Diana turns up at her director friend's house she finds it crawling with cops as his girlfriend Christie has been murdered and the house is now a crime scene. She explains she lent Christie a coat and is there to pick it up - and a cop helpfully finds it on the floor and hands it to her. Are we to believe that a homicide policeman will hand over an artifact from a murder scene to an unidentified woman without making any attempt to confirm her identity, or even if the coat is even hers!? They don't even ask.
Revealing mistake: When Jesse is cleaning out his room, he puts a tape into his tape player, and presses a button down on the top of it. But halfway though the scene of him packing his things away, you can clearly see the button is no longer pressed down, yet the tape still plays. (00:18:10 - 00:19:00)
Continuity mistake: In the beginning, when the two shuttles have docked together, one of the NASA astronauts inserts some kind of key into the door and begins to turn it. When he does you hear a ratcheting sound, however, once the door begins to open and there's a shot from the inside of the uninhabited shuttle, the astronaut isn't holding any type of tool, and still the ratcheting sound can be heard as the door opens further.
Revealing mistake: On the ledge Robert Hayes is attached to the wall by a wire protruding from his shirt.
Other mistake: Most of the obvious misses and awkward parts of the action in the opening can be attributed to the fact that it is revealed a few minutes later being just a drill. However, it does not make sense on any level. The training makes use of live explosives, and at the same time no gunshots are fired but only grenades, with unrealistic trajectories and range. The 'terrorists' don't use their rifles if not to try and bash the good guys on their skulls. That's quite the subpar training, but the top brass are impressed.
