Best action movie mistakes of 1987
Revealing mistake: Riggs handcuffs himself to the depressed businessman. They jump off the building but they're not handcuffed to each other anymore. They used plastic cuffs which could separate during the stunt in case anything went wrong. They break just as they jump, so they grab each other's hands to stay in contact. After they land the cuffs are attached again.
Continuity mistake: Dick Jones brags (admits?) to Robocop, "I had to kill Bob Morton because he made a mistake. Now, it's time to erase that mistake" while Robocop is crouched on the ground, looking away from him from across the room. In the playback, Jones is facing the camera as though it were videotaped or filmed in a studio.
Continuity mistake: In the scene after the prison break, we see Richards, Weiss and Laughlin walking through the city. On the big television screen there is a commercial for The Running Man game show. The footage they feature on the commercial is footage from the episode Richards is in. How could they show footage from that episode if it has not taken place yet?
Revealing mistake: Mac and Dillon go after the Predator. The Predator is sitting in a tree, and Mac points him out to Dillon. They both agree that they see it and take position. Mac crawls underneath the alien and is killed by his laser. The Predator then sees Dillon and lasers his arm off. Dillon's arm falls to the ground with the gun firing. Quickly Dillon turns and reaches for the machine gun around his neck. When he turns you clearly see his bloody right stump and his right arm sticking out the bottom of his jacket. [Note: As far as I can work out, this has been cunningly edited out of the UK DVD version].
Factual error: Austria is famous for its mountains and ski resorts. But certain parts of Austria are quite flat. And the border region between Bratislava and Vienna is VERY flat. No chance to cross the border over a mountain with a ski resort like shown in the movie, unless you take a 600km detour with three more border crossings.
Revealing mistake: When Jack is hanging out of the truck you can see him standing on the hood of the car which Lydia is driving. At some points we get camera view from the back seat of the car. In some angles the mirror inside the car disappear. This is to prevent us from seeing the camera.
Other mistake: When Joe (The American Ninja) pushes the girl out of the moving truck, one sees the stuntMAN (playing a girl) mis-time the fall and land on a large clump of rock and dirt, after which, before the scene cuts, we see the stuntman curl over in pain. Obviously a very painful fall for the stuntman and a very very funny scene for the viewers.
Continuity mistake: In the car chase scene, the escaped convict and police are exchanging gun fire between cars. In the different shots of the police car, the bullet holes in the windshield appear and disappear several times. Also, when three shots have been fired at the police car there are four bullet holes in the windshield.
Continuity mistake: When the two cops pull the stripper over, their car stops in the middle of the road. When Beck and Gallagher pass them later, however, their car is closer to the pavement. Their car moves yet again when Beck looks back at them out of his window. Also notice that three headlights are now on, including one that the stripper blew out.
Factual error: The Joes chase Cobra into the snowy mountains and attack inside the weird cave. One of the Joe's vehicles splits to a driving section, and Road Block flying up in a little fighter. Road Block is holding a large rifle with both hands, yet the fighter goes up and turns around and begins flying at his control but he never touches a steering wheel or anything. Just his big gun. And he does not speak so no voice commands are given. How is he flying with no hands?
Continuity mistake: Near the beginning of the film, the soldiers are filling sand bags with mud. Beletsky, whose hands and forearms are covered in wet mud, puts down his sandbag and takes out a photo of his girlfriend. In the next closeup shot of him holding the photo, his hands are suddenly clean and dry.
Factual error: In the farmhouse bedroom scene, the lead character wakes up and a close up shot of the alarm clock shows it is 5AM. Full sunlight is coming through the window, and an exterior shot shows the sun shining on the house and hay bales. The narrative lead-in just explained that it is early October on a farm near Dallas, Texas. The earliest sunrise occurs near Dallas in October is 6:40AM.
