Plot hole: In the scene where the Wicked Witch is furious because Dorothy and pals have been saved from the poppy field, the Flying Monkey hands her a golden cap. She then dashes the cap across the room. The golden cap is used in the book to summon the Flying Monkeys. They shot scenes involving use of the cap, edited them out, but left this one with the cap inexplicably being tossed about. (00:57:05)
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).
Plot hole: The creature gets caught in the fishing net and (after a struggle that shook the whole boat) freed itself. The scientists, upon drawing up the net, find one of the creature's claws, and thus they now seek its source. Shortly after, while Mark is busy loading a harpoon gun, Dave is protesting, stating, "This...this thing *alive* and in it's natural habitat..." It would seem that at this point, they know the creature is *not* dead, but very much alive. They dive, they see it, Mark shoots it with a harpoon, and then upon surfacing, they argue a bit before reporting what they saw to everyone else. So why after seeing it underwater, fully knowing that "this thing (is) alive," do they act so surprised to see it, as if they didn't have a clue it could possibly still exist?
Plot hole: Mr. Foyt spies on J.J. and Victor to find out more about the Cannonball, yet fails to recognize them when they stop to pick him up.
Plot hole: When Farley is preparing to rescue Simon by towing him up with the rope attached to his van, he drops his "cigarette" into his crotch, causing him to floor the gas pedal. His back wheels begin to spin. This is impossible because the vehicle is still in Park. There is even a camera shot of the "PRNDL" proving this. I guess this goof is employed by the filmmaker to increase the dramatic effect of him subsequently slamming the Dodge into drive a second later and careening through the fence. (01:07:35)
Plot hole: Whilst on the surface a drifting ship is seen and an officer and two sailors are sent to check it. On deck the officer says check fore and aft. The sailor who goes to the right and out of sight is back in 5 seconds. This is not enough time to check his allocated section. The script should have shown the officer check his watch (dial visible) and say something like "you have got 15 minutes". Next shot to show the officer checking his watch again and we see 10 minutes have passed and the men return.
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 court house despite having no way of knowing that she would be there that day.
Plot hole: In the first night that Nyah is in Ambrose's house she meets with Ethan outside the house and they talk for about 1 1/2 min. Then we find out "Ethan" was really Ambrose with one of those "high-tech" masks. My question...After being in bed with both, how come Nyah didn't recognise Ambrose is about 5 inches taller than Ethan?
Plot hole: Considering that this family has been training for the mission for years and certainly have received some instruction in astrobiology, they are awfully carefree around the cute little alien. Any real space farer would be aware of the enormous potential problems with first contact, like incompatible biochemistry (aliens might exude deadly toxins from their skin, be eaten alive by human-exhaled oxygen, etc). They even feed it human food without analyzing the alien; again, this could kill it, make it chemically dependent, cause it to go into a mating cycle, etc. But it's cute alien, so naturally they don't worry about any of this.
Plot hole: At the end when the gang get home to Andy's room, it's night time and the luggage trolley they drove home in is outside the neighbour's house. The next morning it's still there. But we see an ad with the 'chicken man' looking very sad because he lost Woody and the others. How could he have gone to Tokyo, realised the dolls were missing, then zoomed back to Tri County to do the ad the next day? While saving Woody, the toys explicitly say that Andy is returning home the following morning. They must have made it in one night, or they would have missed Andy's return.
Plot hole: When Bond first sees that Willard White is actually Blofeld in the hotel penthouse, Blofeld shows him how he has been impersonating Willard White's voice with a machine. But that only works through the phoneline - out loud it would be different.
Plot hole: Mola Ram has his men knock over a vat of water in a last ditch effort to kill our heroes. First of all the vat can't be that big if it can be knocked down with a few sledgehammers. Secondly, for the amount of water that chases Indy and co. down the vat would have to be big enough to fill the room it's in, which obviously it's not. Third, Indy and co. travel through several large caverns during the mine cart chase, caverns that could easily swallow up any of the water flowing through the tunnels so there shouldn't be any water left to catch up to Indy by the time they stop.
Plot hole: Enola and Tewkesbury make an unpremeditated decision to visit the Basilwether estate. This decision was made on the spur of the moment, and no-one knew about it. but when they arrive, Linthorn, who is supposed to be in London looking for Tewkesbury, is waiting in ambush to kill them. (01:32:45 - 01:34:31)
Plot hole: When falling into the deep, deep hole, the three would be killed upon impact, and the fact that they follow water will not change anything. They will still be falling with more than 180 km/h. The water isn't slowing them down, as nothing is holding the water up. So it will be free-falling too - with more or less the same speed.
