Other mistake: Towards the end of the movie, when Superman drops Gus off at the coal mine, Gus begins talking with the coal miners about him and Superman. He then rips open his shirt (as if he had a Superman costume on underneath). How did Gus know that Clark Kent tore his shirt like that in order to change into Superman, or keeps his suit under his clothes at all? The only people who know this fact are the ones who have seen the transformation from Clark to Superman, i.e. the audience.
Other mistake: The rope is wound round Jack's body and the pole at his back numerous times. When Shishka-Jack falls, the pole gets jammed between the cliffs, but the pole does not break and the rope does not tear. The rope that goes round the pole numerous times simply disappears, leaving the rope intact around only Jack's body in order for Jack to twirl and unravel as he falls. (00:39:00)
Other mistake: When Rowan Atkinson is riding in the train, near the end of the film, he is looking out the window. He is looking forward, then quickly looks backwards. He does this several times in a row, as if trying to see things quickly as the train passes them. But, when the camera pulls back, Rowan's back is facing the direction the train is moving, thus he was looking the wrong way! You can tell by the way the scenery is moving as you look through the window. (01:28:05)
Other mistake: During the miniaturizing scene the technicians controlling the forklift wore sterile gloves, the nurses assembling the syringe did not.
Other mistake: At one point, Indy rolls off of the side of a tank, and somehow gets a strap around one of the guns pointing out from the sides. The end of the barrel has already been blown open by the rock he shoved in earlier. How did the strap get around that big cluster of metal, and then back again so he could climb back on the tank? (01:34:15 - 01:35:05)
Other mistake: At one stage the Angels speak with each other in a different language, so that the people sitting next to them wouldn't understand. Having listened to it for a few times, I realized it was Finnish. Funny though, the thing they actually said there (in Finnish), was totally different than the written translation. (00:41:45)
Other mistake: In the scene where Robin Williams tells Sarah that she needs a 12 to win, she rolls a 3. The next time she rolls, Robin tells her she needs a 7 to win.
Other mistake: After the magnet grabs Slink during the incinerator scene, all the toys grab metal objects to avoid getting torn up. Afterward, they all let go of their metal objects to drop down. However, Slink also drops down despite not holding on to anything because he is made of metal.
Suggested correction: Or, the other toys helped him down.
Other mistake: So let me get this straight: Optimus Prime has Energon Swords hidden in both of his arms, with which he can slice through an entire Decepticon in one chop, yet when he is hanging from a few wires, despite having one arm entirely free, he can't cut himself loose?
Other mistake: Dante and The Agency both have extensive photos and videos of the team's previous exploits. Trouble is that most of it is simply stills and footage from the previous movies in the franchise, often occasions when nobody was around with a camera to witness and document what was going on, certainly not at the angles we see.
Other mistake: While Hermione and Ron watch, cloaked Harry starts up with Malfoy and his two friends as they all stand in the snow. Most noticeable in the wide shot, when Harry spins the Slytherin boy, although the boy's feet visibly disturb the snow, Harry's feet do not make a mark - no footprints whatsoever. (01:02:30)
Other mistake: When Frenzy attacks Sam, the teenager wears straight leg jeans with a narrow leg opening (not boot cut) and thick-soled Nikes, seen in numerous shots, as he kicks at the Decepticon. After the cut to Mikaela (who finds the reciprocating saw), during which Frenzy has already pulled off the bottom of Sam's jeans, Sam continues to kick and scream just before he gets up and runs. Problem is Sam still wears both thick-soled Nikes, neither of which slipped off as Frenzy maniacally pulled the jeans, with narrow leg openings, from his kicking legs/feet. Impossible even in the best of circumstances.
Other mistake: Towards the end of the movie, Carmen hands a guy some 3D glasses with a crack in one of the lenses and says something like "Sorry it's the last one," but less than a minute later hands a different guy a pair of 3D glasses.
Other mistake: Pintel and Ragetti fire the chain link cannonball, and it hits the square rigged mast aboard Interceptor. There's a shot of two men falling from the top of the mast, just before Interceptor's mast crashes onto the Pearl. They are not part of Jack's crew, who are all accounted for aboard the Pearl later. The only one of Jack's crew to die is the Asian man, when he's stabbed by a pirate and falls overboard. Nor can they be Barbossa's crew, because they haven't boarded yet. (01:27:00)
Other mistake: As the Veridian star is destroyed, Picard raises his hand to supposedly shield his eyes from the sun's light, but he is looking in the wrong direction; the sun is behind him, and there is no light on the rest of the front of his body.
Other mistake: When in the tub in Arkansas, Wyatt is bare chested. In bed with Josie he's suddenly sprouted a lush garden of chest hair.
Other mistake: When Rusty is talking to the trucker on the C.B. radio, he hands the microphone to Kevin. Kevin never presses the talk button on the microphone when he is talking to the trucker.
Other mistake: When Elastigirl is chasing the high-speed train, as she is in the middle of making her second final jump to reach the train, if one were to look closely, the train actually drives right past her before she lands. (00:31:40)
Other mistake: Near the end of the closing credits, when the Warner Bros. Copyright appears, you'll see the very first word "All" spelled incorrectly as "Al" in "All material is protected by Copyright Laws of the United States and other countries throughout the world." (01:26:40)
Other mistake: Towards the end where they steal the chip, they are detected and about a million security guards are all running around, yet 30 seconds later, the only security guard is one man with a shotgun. What happened to their big army of security guards? (01:41:30 - 01:42:55)
Suggested correction: This isn't a mistake. Bishop had been directed to a part of the building where there weren't any security guards; this was shortly before one of the guards found their camera feed. The guy with the shotgun was the only person to head into that location. Unlikely maybe, but possible.
