Factual error: When Gantz fires Nolte's gun at Nolte, he fires 8 bullets out of a six shooter. (00:18:45)
Factual error: Col. Trautman should be wearing his rank insignia on the flash (small patch) on his beret. All officers wear their rank on their flash, enlisted men wear the unit crest. (This error was corrected in Rambo II and III.)
Factual error: Towards the end of the movie, when Clint Eastwood is flying away from Russia, the Russian cruiser is really either an American Leahy or Belknap class cruiser.
Factual error: Kathleen Quinlan is named Janet Dunn, but when Gene Wilder looks at the newspaper and sees the headline about her murder, it falsely says her name is Janet Stone.
Factual error: Inside the nebula, the Enterprise rises from below and fires a photon torpedo at the Reliant, striking it directly on the dorsal torpedo pod. Watch as the torpedo hits and the pod explodes. Large pieces of the bulkhead explode outward, then begin to fall downward towards the saucer section before they cut camera angles, despite there being nothing dragging them in that direction. (01:31:25)
Factual error: When the God Skills Society disciples build the altar in front of Ching's family temple, they just cover the horizontal ladder-like part with only a cloth strip and then place two candles and a heavy bowl with incense sticks on top without making the cloth sag between the rungs or the items fall off, since there is no solid board underneath.
Factual error: After the match with Thunderlips the newspaper says it was Wednesday, May 15 1982, but that day was a Saturday.
Factual error: Pretty much everything that the ferrets do, Kodo and Podo, ferrets would NEVER do. Ferrets don't sound like that. Ferrets can't jump that high and that far (when the one attacked minister Zed).
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)
Factual error: When Conan cuts off Thulsa Doom's head, and throws it over the parapet, it hits the stairs below and rolls a little way down. Not only are there absolutely no marks left on the stairs (there should at least be a small amount of blood), it sounds like something plastic is rolling down there.
