Revealing mistake: When Matrix hits the button to blow up the village, you can see that there are only cardboard stand-ups of men next to the buildings blowing up. Also, for some reason the top of the watch-tower also blows up even though Matrix never put a bomb there. (01:11:00)
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)
Revealing mistake: 1955 skateboard chase scene around town square. Note in this scene a metal device has been added between the kicktail and the back truck of the skateboard to create the sparks, then disappears and reappears throughout the whole chase scene. (01:03:40)
Revealing mistake: In the scene where Cobb's mean attack Emmitt, Mal shoots one of the men in the hand. The shot pauses long enough to show that hand is quite a cheap, plastic-looking fake prop hand.
Revealing mistake: After the cowboys have terrorized the village at the beginning, the girl finds her dead dog and starts crying, when she picks it up it's painfully obvious it's a stuffed toy.
Revealing mistake: Take a good look at the lower right corner during the 'Hearts on Fire' training sequence at a barn in Russia. Rocky does a few leaning sit-ups; at that moment the cow in the lower right corner moves backwards. When you look closely you'll see it moves back too quickly and anatomically incorrectly, thus revealing it's a fake head attached to wheels or something. (00:57:45)
Revealing mistake: In a scene towards the end, we see a crowd of Vietnamese on a riverbank firing their machine guns into the trees...one soldier clearly walks directly in front of another soldier who continues firing away without hitting him.
Revealing mistake: When Bronson is chased up onto the rooftop by one of the gang members, Bronson pushes the guys over the edge of the building, and it is visible that it is a dummy taking the fall.
Revealing mistake: In the scene where Sonja's sister is escaping from the temple she is shot with an arrow whilst on an aerial slide. Her body hangs limply and is met at the end of the slide by Kalidor. However, the limp body is a stunt *man* in drag.
Revealing mistake: Remo, clinging to a tree trunk, is shot at by Grove using a vehicle mounted machine gun. Pieces of trees are seen shot but this is only sound and special effects. There are no muzzle flashes from the machine gun, the cocking handle does not move in time with the shooting, nor does the cartridge belt move through the weapon.
Revealing mistake: During the Army assault on Ortega's compound, Jackson is shown as he uses a machine gun to clear a long balcony of enemies. The third person he kills here is hit several times, but does not fall over the railing. Instead he slowly and carefully climbs over it, lifting one leg over at a time.
Revealing mistake: When the guard that wants to kill the fool is hit by an arrow, you can see the outline of a protection plate or something like that under his clothes.
Revealing mistake: When Jack and Joan escape in the F16, if you look at the back wheels, you can see the car driveshafts that drive the wheels. Jet aircraft don't have driveshafts.
Revealing mistake: At the beginning of the film when Nester and Opelka and at least two other Americans are attempting to run towards the chopper, you hear a series of Vietnamese mortars which hit two of the Americans, followed by screams. If you look real closely at the last mortar to hit the second American, it is a scare-crow type figure dressed in military fatigues that takes the mortar hit.
Revealing mistake: Just before Michael and Ellie get out of his car, a fire extinguisher is seen mounted above the dash. Michael opens the hood and the engine begins smoking. Michael reaches into the car for the extinguisher. You can see through the windshield that he is handed another extinguisher instead of removing the one from its mounted spot. The mounted extinguisher is still visible in its holder. Likely done to preserve pacing so he doesn't have to fumble with the clamps on the mounted one.
Revealing mistake: At the start when Max is knocked of his truck, the plane circles and the shot switches to in front of the camels. If you look at the ground you can see the tyre tracks from previous takes.
Revealing mistake: After the machine runs over the terminal, killing him, when the camera shows the legs being run over again, it's easy to tell that they're dummy legs.
Revealing mistake: During the opening assault, notice that the sandbags of the enemy fortifications are more like fluffy pillows; they are squashed under a single person leaning on the bank, and they wobble and nearly fall over when Carrasco himself brushes the hip against them walking by. (00:04:30)
Revealing mistake: When he old lady jumps over the counter to attack Jack with a cleaver, she is replaced for the physical struggle by a younger person; you can see her face when the two struggle against the table. (00:04:55)
Revealing mistake: When Manny goes to lay down and uncouple the two locos at the end, a 7" icicle is flapping in the breeze.
