Plot hole: When Finnegan is in the water and the explosive charges go off, Finnegan should be dead from concussion, and the explosives are big enough to have caused his death by them flinging him quite high out of the water. What happened to Finnegan was pure fantasy.
Plot hole: The seaplane should have a watertight hull so the two jumping out the bottom makes no sense when they should have used the same exit at the rear of the plane that they loaded the jet skies with.
Plot hole: This TV movie uses a lot of flashbacks to the previous 4 installments, by having people saying to each other, "Hey, remember that time when we..." a bit more than usual. In the village of the Minotaur, Iolaus remembers the fight from Hercules and the Amazon Women where he dies. That is also the reason why this flashback is interrupted just before that point. But at the end of the Amazon Women story Hercules used magic to jump back in time and change history so that the whole adventure had never happened (next making sure that it would not happen all over again). Obviously they wanted to use some cool action footage from all the TV films. But Iolaus could not remember these events as it happened in some cancelled version of the future. (Hercules remembers, but he wasn't going to tell anyone, and that's what we have to go on).
Plot hole: After escaping from execution, the assassins still made use of throwing knives out of their garments as they ran through the city. These would have been removed from them before they were shackled in the cell.
Plot hole: How did Carolyn Fry get out of the cave in the canyon to confront Riddick at the Skiff? Riddick strained to roll the rock into the cave entrance, and he was a big, strong man from a position of good leverage. How did Carolyn and the other two push the rock out of the way so that Carolyn could get out? And, then, how did Carolyn mange to push the rock back into place? It was still there when she and Riddick came back from the Skiff to bring back the other two.
Plot hole: Bond lies to Tanya on the date the embassy would be bombed (Karim and Bond knew the 13th) and Tanya denoted the deception by telling Bond when he came in the decoding room she thought it was the 14th. How did Grant know to A: be on the train and B: have an entire escape plan set up for the wrong day?
Plot hole: In the scene where Ba'al goes through the stargate and arrives in 1939, the event horizon from the stargate puts a hole in the haul of the ship. Later when SG1 goes through the stargate the hole is covered with ice. The event horizon created from SG1 would have been the same as the previous one and removed the ice from the hole.
Plot hole: Lois and a friend of hers are watching Non and Superman fight. But this is totally senseless, because Superman had been flying around Metropolis and chances are slim that he appears in the very same spot to let Lois watch him. And, second and most important, should any doubts arise, the panning angles of the camera never show Lois's building, with the big broken window and the flag poles.
Plot hole: Part of the reason that the Jackal killed Lemont, asides from him being very annoying and money grubbing, was the fact that he wasn't going to give up the blueprints and plans for the device he made for him. Made a big deal about how he had to turn it over, and he tricked Lemont into going out into the testing ground with him so he could kill him. Then in the next couple scenes, the FBI is investigating Lemont's warehouse after they find Lemont's body, and Delcan finds the plans for the device Lemont bluilt for Jackal. This makes no sense. The Jackal was so adamant about getting those plans back, and even killed Lemont over it, it's just baffling to think that he would not have returned to the warehouse to get them after disposing of Lemont. Not doing so lets the FBI find it exactly as shown in the film. The Jackal is show to be very intelligent and has been doing this line of work for 20 years. And as Declan says, he's not inclined to make mistakes... Especially a mistake like that. (01:02:35)
Plot hole: After Riker takes the Enterprise through the Briar Patch to communicate with Starfleet he returns to rescue Picard from the collector in mere minutes, even though it was supposed to be a 2-day journey.
Plot hole: Gerry's wife uses a rocket boot to break through a window and then slides down a curved wall to get to their son. She does so gracefully and takes off running. Gerry slides and takes a hard tumble and rolls down, landing on the ground. The next shot shows Gerry running behind his wife and not too far away as they reach their son. Even if it was to show a little time passing, there was not enough distance between where they broke the window and their son for Gerry to have picked himself up and catch up to his wife before reaching their son, especially with his wife being a worried mom doing a full on sprint to her kid.
Plot hole: Near the end of the film, the crippled Thunderbird 5 is about to catastrophically re-enter the Earth's atmosphere and burn up. Predictably, the younger Tracy brother restores control, saves Thunderbird 5 and all on board. A few seconds later, a computer announces that Thunderbird 5 has resumed a geostationary orbit (such orbits are only possible at an altitude of 400km) My point? Pulling out of a fall, climbing 370km in a few seconds, and then stopping dead 400km up would have required such a massive acceleration/deceleration that everyone on board would probably have been pulverized, even if it were possible for a badly-damaged space station to move that fast.
Plot hole: During the nova scene, everyone is tying down the sails after securing themselves with lifelines to the mast. Jim and Silver are on the front and Silver is knocked off. Jim is then all dramatic and runs to grab Silver's lifeline which seems to be coming from above, and pulls Silver up like a pulley. How come? The lifelines were attached to the mast, so Jim's action is pointless... even if he could do it, because a shot later both lifelines are streaming right to the mast, leaving no room for a pulley of any sort.
Plot hole: When Eve is being led out to the airplane, she bolts when two shots are fired from inside the house (presumably Anna firing at Thornhill, not realizing that the gun was loaded with blanks). Moments later, she jumps into a car driven by Thornhill, and they escape together. There is no way Thornhill could have gotten there that fast, given that he was in the house only seconds earlier.
Plot hole: At the beginning of the movie Ben's wife meets Kim who is 'fresh off the boat' from somewhere in Asia. Whenever she speaks to Kim she speaks in English, Kim never answers. We therefore assume that Kim does not wish to speak to Ben's wife or Kim cannot understand English. After Ben's wife takes Kim home and settles her in a bed. Kim says something in English. Ben's wife answers Kim in Chinese or another Asian language. Why. did Ben's wife not try speaking to Kim in her native language at the outset? Doesn't make any sense to me.
Plot hole: Harry can now see the thestral creatures because he witnessed Cedric Diggory's death in "Goblet of Fire." However, he should have been able to see the thestrals after Professor Quirrell died from Harry's touch in "Philosopher's Stone". Quirrell crumbles into dust (dying) while Harry is still conscious, watching, and fully aware of what he is seeing, thus allowing it to fully sink into his consciousness. Harry faints "after" Quirrell is dead and as Voldemort's spirit passes through his body. Nor does it only have to be a friend or loved one who dies before the thestrals can be seen - it can be anyone, including an enemy like Quirrell. There only has to be an emotional response to the death, which can be love, hate, fear, shock, etc. (In the book, Harry did not see Quirrell die, but that's irrelevant to the film).
Suggested correction: JK Rowling has said that in order to be able to see thestrals the death has to "sink in" psychologically with the person. Which was her explanation for why he couldn't see thestrals even though he witnessed his mother's death. Given Harry's age and the way Quirrell died, it is possible that Quirrell's death didn't have enough of a psychological impact on him to "sink in." After I first personally witnessed a violent death, I didn't feel the impact until a few years later. It can take time.
