Plot hole: Detective Mason Storm has been in a coma for a number of years, so how is it that on the day he awakens from the coma, he not only has the strength to move his bed down corridors, but also knows the layout of the hospital?
Plot hole: In the Banker's Office, Bond takes the strap from one of the window blinds to facilitate his escape. Overlooking the large quantity of cable he ties round the belt of the villain and his own belt, there must be an awful lot of strap for one blind to allow him to drop from that high up to the ground (well over 50ft?).
Plot hole: According to the flight recording, Odyssey was on an uncontrolled pull towards the Tet as Jack says, "We're not getting away from this thing." So even if Jack jettisoned the sleep module where Julia was in, the module should not be able to get away as the whole ship is being pulled towards the Tet.
Suggested correction: It can be assumed that the jettisoned module has enough "jettison power" to force it away from the command pod. And in turn that force would move the pod further towards the Tet. It's reasonable to assume the Tet couldn't pull the module that was moving away, under dramatic force, and to which it didn't have line of sight (which was blocked by the pod).
Plot hole: In the makeshift morgue when Simon and Matthew first fight the vampires, Solina is shot and pinned to the wall with a large silver nail and remains calm and unaffected. However, moments later Marcus is fighting with Simon and grabs one of same kind of nails but must drop it when it burns his hands. It makes no sense that Solina had no adverse reaction to the nails at all when Marcus reacted so violently. (00:42:00 - 00:57:50)
Plot hole: The secret CIA base at Kamp Woody was underground. Kids searching for years have combed the camp, but never found it, but when Cody is going down the escalator, you can see bright skylights on the roof. If the sun is able to shine through, that means the skylights aren't hidden, and the kids would be able to find the camp.
Plot hole: Even if someone would make all nuclear powers launch their nuclear missiles and then destroy them you still wouldn't have a nuclear weapons free world as most of those nations have plenty of nuclear weapons in reserve. A lot would be even be armed and ready to go for a possible second strike. (01:24:10)
Plot hole: During Riggs' last fight with Adolph, Adolph holds the knife in his own hand as Riggs forces him to stab himself very slowly. At any point, Adolph could simply have let the knife fall or just tilt down before that happened. Nothing Riggs is doing is making such impossible. "Locking" his wrist does not prevent him from letting go of the knife. It only prevents him flexing his wrist. And this guy is a trained killer, fighting for his life. Better to battle for control of the knife than just let it kill you.
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: When Qiu is leaving Emilien, she ties him to a chair, sitting on a raised platform. This is to make it possible for the big ball to hit Emilien. But, when Daniel arrives, Emilien is able to throw himself into the trunk, which means, that if Daniel didn't show up, Emilien could have just thrown himself to the floor instead. So if he would be off the raised platform, he would never have been hit by the big ball in the first place.
Plot hole: When Eldon checks out the address Van Meter gave him he finds where Orchard and Sidwell are living. All well and good, except: A) The utilities bill is in the names of Orchard and Sidwell, who are known wanted felons in L.A. and B) even more implausibly, the bill is in BOTH their names.
Plot hole: Uncle Dave, the elderly owner of Wonder World, takes a bullet to the torso, yet he is able to stand at a podium to introduce the new character, while all three of the erstwhile heroes, who received arm wounds, are in wheelchairs.
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: 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: When the policeman asks Kirsty at the beginning who came when she solved the box she says the Cenobites; she had no way of knowing what they were called. Frank only told Julia; Kirsty didn't hear it anywhere and the Cenobites themselves didn't tell her either.
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: In the first part of the movie, when the crime boss shakes down the club owner, he leaves a briefcase bomb inside the office. When he walks outside to explode it, the first thing that explodes are the club's billboard matinee lights, nowhere near the office, then the club explodes outward as it should from a bomb.
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: In the locker room scene after Rocky's loss to Clubber, we see Mickey take his last breath and Rocky lays his head on him and starts crying. Doctors were present, wouldn't some effort of CPR or resuscitation have at least been performed?
