Other mistake: How did Trent (who started as a six-year-old) end up with an adult-size watch and bracelet?
Other mistake: Jed has eight rounds on him/in his pistol. He tells Chad to go to his saddlebag to get another round of ammo and keep it in his pocket. Jed tells Chad "Let's play catch the bullet" since Chad (not his marshal dad Britt) is the only MacMasters there. Jed fires six rounds before Britt shows up on top of the hill, then two more (eight rounds). Jed shoots a ninth and tenth round before he tells Chad, "Get that ammo." Chad is never shown giving Jed the ammo from his pocket, but Jed keeps shooting. (01:13:42 - 01:17:46)
Other mistake: When Al Pacino reads the magazine (Grazia) with the news of Maurizio's wedding, the article is probably a reproduction (with the actors' picture in place of the actual Maurizio and Patrizia) of a news story about the actual wedding, so the details conflict entirely with the fabricated story. You can easily read (in Italian of course) that they met in 1971 (1978 in this movie), there are over 500 guests to the wedding (much more of a private affair here) and Maurizio had to ask some of his friends to introduce Patrizia to him and asked her out, which is the opposite of what happens here. (00:28:40)
Other mistake: The way the man fell onto the hood and then the road, landing on his back, after Sami hit him from behind while going fast defies physics. He also landed too far to the left of the driver's side for being hit with the middle of the front bumper. (00:35:41)
Other mistake: After Ken shoots the pregnant lady, she rolls her head to the side, apparently to indicate death, but her stomach movement shows she is still breathing. (00:01:46)
Other mistake: After Finney got off the mattress, he was walking in the dark (at least a few steps). The screen went completely black, but Finney - who had not been in that basement before - was able to reach up and pull the cord to turn on the bathroom ceiling light. (00:29:50)
Suggested correction: What the viewer sees and what Finney sees would be different; his eyes probably see low level light better than the camera. There would be a low level light going into the corridor from the room Finney was in. This would possibly be enough for him to see the light cord. We don't see the light cord, so we don't know how easy it was for Finney to see it.
Other mistake: After seeing Joe Montana play in Super Bowl XIX, young Kurt said, "I knew I wanted to be that guy." When he goes outside to pass the football, young Kurt has "Warner 13" on the back of his jersey - not Montana's #16 but the #13 that he could not know in advance that he would eventually wear during most of his adult career. (Jersey numbers are not necessarily that available for a player to have his pick). (00:02:02 - 00:02:33)
Suggested correction: This is trivia at best, certainly not a mistake. While it's true he wore #12 in high school, there's no reason he couldn't have liked #13 as a child. And, many key position players do get to pick their number, from the available range, which Kurt certainly did.
Other mistake: In the first two minutes of the film the registration number of the small aeroplane is written in reverse. (00:01:48)
Other mistake: The crossbow arrow that went through Jamie's shoulder area had different positions/angles and was not always visible (in front or back) when it should have been. The crossbow arrow also did not seem to be long enough. It was not a mini crossbow arrow (3-4" where in front with maybe 5" in the back and a mini is only about 6.3" total); regular lengths are typically 14" - 20"+. (01:15:10 - 01:17:00)
Other mistake: Randy is using her laptop to watch Staci on the surveillance camera. It is just past midnight, but the time at the bottom right of the camera image says 12:18 PM (noon), rather than 12:18 AM. (00:42:00)
Other mistake: Grace Lewis shot a man in the head when he was standing less than three feet from her, but Grace did not get any blood splatter on her face or elsewhere. Neither did George Clements, who was standing near both of them. (01:15:03)
Other mistake: The same 2 family photographs decorate the family home over and over and over again. Sometimes one or two of the members has been Photoshopped out.
Other mistake: At the end of the movie the soldiers handcuff Farid despite the fact that he only has one hand.
Other mistake: William Tillich (AKA Bill Tell) had one suitcase which could not possibly hold enough sheets (or thin blankets) to cover/wrap all the furniture in his motel room like he did. (His suitcase was not very large and also contained his clothes.) He covered an even larger area of furniture in Gordo's house. It isn't clear if he used his own sheets or just happened to find the same kind in Gordo's house.
Other mistake: Pierre bumps into Tae-ho and asks "Oh, how's Captain Jang? Beautiful as ever?" in French. Tae-ho then says "She asked me to tell you" in Korean, but the captions read [in English]. Pierre replies in French, to which Tae-ho replies "If you talk to her again, she'll kill you" in Korean, but the captions incorrectly say [in English] again. (00:15:50)
Other mistake: Mike said, "I don't feel too good [sick from drinking Mexico's "dirty water"]." Rafo responded, "Run! It's gonna come out" and Mike walked into the weeds. Mike apparently "forgot" about his impending diarrhea because he was able to run up to the road behind Rafo when their car was being stolen. (00:41:59 - 00:44:00)
Other mistake: The bottle of alcohol (whiskey?) and glass on Morgan's bookcase appear to be the same as the ones the Game Master has in his office; the bottle is emptied to the same level (too similar to be a coincidence). (00:03:23 - 00:06:57)
Other mistake: Blood gushed out of the bound man's lower inner arms that were slit with a knife from below the elbow to the wrist (then turned toward the ground). A switch to an aerial view showed no additional blood dripping (while he was still alive). Also, blood would not pour out of his arms to the ground in a horizontal stream like it did. (00:02:04 - 00:02:27)
Other mistake: Dr. Pazzo (which literally means "Dr. Mad" in Italian, incidentally) turns towards the computer with the voice synthesizer before the phrase is spoken. (00:51:20)
Other mistake: The issued sidearm for the Spanish National Police is the H&K USP 9mm Compact, which has a capacity of 13+1 bullets, and the Civil Guards' is the Beretta 92fs/M9, which is a 9mm and has a magazine capacity of 15+1 bullets. As of 2020 the Beretta is being phased out for the H&K USP C. The police officer fires a total of 5 bullets from his Beretta then the slide locks back because its dry. He has no magazines for reloads either. I highly doubt the Spanish police issues 5 bullets to their officers. (00:33:00 - 00:35:30)
