Visible crew/equipment: After Conan is set free from slavery he finds a cave where he removes a sword. When he climbs out of the cave you'll notice someone's hands near his feet pushing up his shackles. (00:29:25)
Visible crew/equipment: At the beginning of the movie, Sheriff Teasle escorts Rambo to the outskirts of town. As the sheriff drives off, the boom mike is visible in the reflection of the car's right rear passenger window. (00:07:30)
Revealing mistake: Near the beginning of the film when Deckard and the other cop take off in the car to go to the police station, you can see the cables lifting the car up into the air. (00:10:05)
Continuity mistake: Paul Kersey boards a bus where the line number reads 990. When he gets off, the number is 99. He could not have changed buses because the number of the bus itself remains 8027 throughout. (00:54:50)
Revealing mistake: Every time Dar's village is from the hill, it is a blatant scale model or matte painting where all the people and animals are suddenly missing.
Continuity mistake: In the training simulator at the beginning of the film, after Sulu and McCoy have both fallen, McCoy has his head resting on Sulu's hip at first. Then, in the next shot, his head is resting closer to Sulu's knee. (00:05:50)
Factual error: When Alan gets the message that his security had been suspended at Encom, the computer gives a Date/Time stamp of Sept 22, 18:32:21 PM (6:32 PM) But at the time, it is shown to be pitch dark outside. Isn't 6:32 PM early to be completely dark outside in mid September (keeping in mind that no matter how far east one is, it can never be full dark outside at that time, at that period of the year). Also, why would the Time stamp have "PM" in it when it is using the 24-hour clock? (00:10:40)
Other mistake: During the shots set in Los Angeles, a group of pedestrians can be seen looking directly into the camera and smirking.
Revealing mistake: When Reggie and Jack are following the Porsche they're replaced by obvious stunts. Eddie Murphy is a heavier and older man with an afro hair, for example.
