Character mistake: When the front door of the old F-unit is refusing to open the guys put their shoulder to it. The door they are trying to bash outward actually swings into the area where they are standing. If they really wanted to go out that door they should have unlatched it and pulled.
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?)
Character mistake: When Rocky makes his speech after his fight with Drago, he says that it's better that one person fights another instead of a million fighting a million (a US USSR war). The Russian translator misinterprets his speech and says that this is better than a million dollars. You don't have to understand Russian (although I do) to hear the translator says million dollars to confirm this blunder of a mistake. (01:22:25)
Character mistake: In the showdown scene between the Vietnamese officer and Rambo, the Vietnamese officer empties an entire magazine at Rambo from only about 20 metres away but only manages to hit the ground around Rambo's feet. What was he doing, aiming at his feet? He deserved to get blown up to bits for that effort.
Character mistake: In the scene where Sophia confronts Celie in the cornfield, she starts by saying, "You told Harpo to beat me". Later she tells Celie, "If you want a dead son-in-law Miss Celie, you keep on advising him like you do". Harpo is actually Celie's stepson, NOT her son-in-law.
Character mistake: During the conversation in the study about who is blackmailing who, Mrs. White mentions two of her five husbands: An illusionist who disappeared and never reappeared and a nuclear physicist who was found dead at home. During the last ending, Mrs. White says "So this has nothing to do with the disappearance of my nuclear physicist husband or Colonel Mustard's work on the new top secret fusion bomb?". However, during the conversation in the study, Mrs. White says her illusionist husband had disappeared and her nuclear physicist husband was found dead at home. So the correct term would be "So this has nothing to do with the disappearance of my ILLUSIONIST husband or Colonel Mustard's work on the new top secret fusion bomb?". (00:21:05 - 01:27:35)
Character mistake: When looking at the newspaper about Chester Copperpot, the caption under his picture reads, "Reclusive scavenger claims, 'I have they key.'" It should read "I have the key."
Character mistake: Baxter and Granville complain about Brewster getting airtime on TV during prime time and running TV spots in all 52 states "just in case any New Yorkers are on vacation!" (01:08:00)
