Plot hole: Jamiel delivers Ali Baba's ransom note to Hulagu Khan by throwing a knife, and the shocked Khan and his guards look to the window. Since Jamiel does not duck away immediately, he should have been seen and identified immediately, but nothing of that sort happens.
Plot hole: Stephen dies after he was "taken off machines", at least so his wife tells the kids. But when he was shown in the hospital he was attached to no life-supporting machines except an oxygen tube in his nose. (01:33:25)
Plot hole: Alain joins the Legion, goes through extensive training and eventually gets his photograph taken. That's how Galgani recognises him and sends two men to kill him. They arrive with a platoon at the fort just after Alain, Mackintosh and Luther. The photograph would have taken a while to get back to France and then the two men would have to go through the same training. So how do they both end up in the same fortress after they joined the legion long after Alain?
Plot hole: There's no good reason for Hinx to attack Bond on the train. Blofeld was expecting him to turn up at the crater, that's why he sent the car to pick them up.
Plot hole: In the end of the movie, when Willy Wonka decides to visit his father, his father does not recognize him until he looks at his "rare teeth." But the wall of newspaper printings that Charlie was looking at included a recent enough picture of Willy that the father would have definitely recognized him, before seeing his teeth, as Willy doesn't look like a normal person with that outfit.
Plot hole: When Marty Wolf comes out of the pool he is blue from head to toe yet with all the swinging of his hands and dancing, let alone the mirrors in the hall, he does not notice he is blue until he has put orange dye in his hair. How could he miss it?
Plot hole: When the two Legionnaires open the gate of the Hadrian's Wall, they lean forward with their shoulders against the doors as if to push, but they are really pulling. (00:33:10)
Plot hole: Although Marty rips the fuel line, not all the fuel would have drained out of the tank. Only the fuel that was already in the fuel line would have leaked out, meaning it could simply be patched, bled and the engine would run without a problem.
Suggested correction: A cut fuel line could absolutely drain the tank. Even if not a direct route with respect to gravity, it could still create a siphon effect and drain the tank.
Plot hole: Silva spent years planning his revenge against M, yet the ability to carry out his plan depended on conditions that were entirely out of his control, such as being captured by MI-6 despite having no way of knowing that Bond was coming for him, and only escaping custody because Q triggers the Trojan - there's no way Silva could predict when that would happen, could have been hours, days, weeks, or never. He then ambushes M at the courthouse despite having no way of knowing that she would be there that day.
Suggested correction: His plan was always to blow a hole in the tube to have a train crash at that location. This would have caused mayhem and take up a lot of resources (police/ambulance/fire). Bond chasing him had no impact on this part of the plan. Then when his team picked him up, his team would have known where M would have been on that day and would have driven him there. With resources on high at the train crash site, it would have made it easier to reach M.
This aspect is a bit of a plot hole for me too - one of the factors outside Silva's control is when he can escape MI6 custody, which depends on when Q triggers the 'Granborough' Trojan, which Q only spots with a bit of help from Bond. That triggering could have been hours, days, weeks or never - pretty fraught with risk to rely on individual(s) making that happen at a plot-convenient moment... otherwise Silva has a bunch of associates hanging around London for a few days permanently on a few minutes alert for a random event.
Plot hole: When Fogg convinces the cargo ship captain to take him to Shanghai, he pays for the passage of himself and two of his colleagues. One of these colleagues is Aouda, but as Passpartout is not there, the other one must be Fix. Why, then, does Fix have to pay for his own passage? If you notice, Fogg seems surprised to see Fix on board.
Suggested correction: At no point do they travel to Shanghai. They travel from India to Hong Kong to Yokohama. There is no scene where he negotiates with the cargo ship Captain. And he is definitely not surprised to see Fix. Are you sure you were watching the 1956 version?
Suggested correction: Just in case Passpartout does show up at the last minute? Also, knowing Phineas Fogg, he has probably already hired Passpartout's replacement and it is for him.
Plot hole: On arrival at the Summerland castle the Polar Bear King becomes human during the midnight hour (as part of the spell) and performs his husbandly duties with his carry-on wife. Why did he not become human during the journey from Winterland to Summerland which took several days? (00:32:40)
Plot hole: During the boxing match where Eddie Murphy is wearing the special contact lenses, he sees that Owen Wilson's life is in danger. So much so, that he rushes out of the ring instead of doing his usual grand-standing. But when he shows up at the tower to rescue Owen, he has on pants and a shirt. I guess he figured Owen could hold out long enough for him to get dressed?
Plot hole: When the Griswolds are at Wally World, supposedly the only people there are the guards. Who operates the rides for them?
Suggested correction: The guards also knew how to operate the rides.
Original mistake is correct. There were only 2 guards. 1 they kidnapped. The other they left lying like a dog until he could call the police. Therefore, there was nobody to operate the rides. Besides amusement parks don't train security to operate the rides.
Plot hole: At the end of the movie, when the water drains away, there would be no way for a) the amount of water to drain away that did and b) for the mammoths that came through to be completely dry. (01:16:20)
Plot hole: When Xander is driving onto the bridge, chased by the police cars, we see that there are police cars also blocking the end of the bridge to stop him getting away. How come none of them noticed the ruddy great ramp sitting alone in the middle of the bridge and moved it? It wouldn't take a genius to work out what he might do.
Plot hole: James Bond shouldn't have gotten away at the end of the airport scene, where he steals an aeroplane and pretends to be a flying instructor. He had no wings with which to fly away, and he ended back up right outside the airport. So, the henchmen, who seemed to still be chasing him one shot before he parked, should have been right on him, waiting when he got out of the plane.
Plot hole: A nuclear armed stealth fighter is accidentally sent back in time to 1940's Nazi Germany. After the Nazis capture it, two days later they drop a nuclear bomb on the United States. There are several basic problems here. Firstly, if the Nazis captured advanced technology, wouldn't they spend more time taking the plane apart and interrogating the captured pilot? How on earth did they manage to train a pilot to fly the stealth in such a short length of time? And how did the stealth fighter manage to reach the U.S. from Germany when in-flight refuelling was unknown then?
Plot hole: Bond goes after Lupe after she leaves the casino table, and they have quite a lengthy, hush-hush conversation. It's a casino, and there are cameras everywhere. Certainly, this would have been brought to Sanchez's attention since he was already leery of Bond and possibly Lupe.
Plot hole: Slater decides to render the nuke inert by punching in the wrong code three times. However, when he does this, the nuke becomes armed, and Travolta reveals that he is one step ahead by having used a special kind of circuit board to produce this result. Two questions: One, once Slater has armed one nuke, why not arm them all? You've got nothing to lose, and you can keep Travolta from getting them for whatever evil purpose he has in mind. Slater plans to send them all to the bottom of the copper mine anyway, so just arm them all. Two, Travolta later arms a nuke himself, and then smashes the keypad with his gun. Well, if you can do that, why doesn't Slater just smash all the keypads as soon as he gets the nukes? Travolta would be defeated; movie over.
