Continuity mistake: After chasing down Sully, the yellow Porsche is totally wrecked on the left side, until Arnie drives it away, and it's fine. Later, when Arnie and Cindy arrive at the hotel, the car is wrecked again. (00:39:50)
Visible crew/equipment: When Mrs. Peacock turns on the cellar lights, a piece of lighting equipment is visible to the left of the screen. (00:47:45)
Revealing mistake: When Charley stabs Dandridge in the hand with his pencil, he stabs the hand holding him by the neck. The depth of the wound on Dandridge's hand reveals that the pencil should have stabbed Charlie in his neck and given him a severe wound, if not kill him.
Revealing 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: Glenn Close's outfit changes four times during the same courtroom scene, while she is giving her opening statement in front of the jury.
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.
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...
Character mistake: When Schaeffer, McFee, and Fergie walk down the dusty road to Amish village, Western gunslinger style, they make a silly mistake no cop would make - they assume that Amish villages are unarmed and undefended. No so. The Amish have no prohibition on guns and almost every house would have at least one hunting rifle or shotgun. The three bad guys are risking being shot to bits before they get halfway down that hill; they don't even make an attempt at concealment. (Wouldn't they also at least think John - a police officer - would still have his gun or might have got hold of a firearm from the Amish?)
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 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.
Continuity mistake: In the scene where Captain Rhodes is first introduced. Initially, his captain insignia is horizontal (correctly). After a few shots in the same scene, his rank is now vertical.
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: Dabney Coleman is chasing Tom Hanks and Lori Singer into the Senate Office Building and in one shot has his flip-up shades on and the next shot they're gone. All in an impossible split second.
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.
Continuity mistake: When Grove is shooting at Remo with the handgun and Remo is ducking the bullets, the trees behind Remo change position throughout the scene.
Continuity mistake: When Jennifer finds the small boy, she removes a sheet from a mirror. In the next shot the sheet is draped back over the mirror again and then gone again. (01:35:50)
Continuity mistake: When Dutra forcibly grabs Abbey's hand and bends it, her hand is palm up. When the shot changes, her hand is palm down.
Revealing mistake: On the ledge Robert Hayes is attached to the wall by a wire protruding from his shirt.
Suggested correction: Not true, the ledge was only 2 feet off the ground.
Continuity mistake: When Dalton is having his picture taken with his camera by the blonde next to the pool, she has his camera. Christopher confronts him, then in the next shot Dalton now has the camera and the blonde is holding red roses.
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.
