Plot hole: When Bryan is shuffled in at "The Baywatch" as one of the dancing extras, wouldn't the director of the film notice that one of his beach dancers (Bryan) is actually dressed for cold weather rather than a day at the beach? He's wearing sweats and a hooded sweatshirt, and he stands out like a sore thumb with all those girls in bikinis around him.
Plot hole: After Cher is robbed, and calls Josh to get a ride home, she does not tell him where to pick her up. She just says she's in Sun Valley.
Suggested correction: Well it cut to when she was in the car with him. Maybe she called him again later offscreen to tell him where exactly she was or maybe he guessed where she was (maybe she had told him another time where she usually goes in Sun Valley).
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: At the concert in Crowley Corners, Miley announces that she will sing a new song she just wrote, "The Climb." Somehow the band and the backup singers all know the words and the music.
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: Wouldn't the bomb (when in the back of the truck of the bad guy driving away) vaporize him, considering he wasn't that much far apart than Allison was when she was tied up? He is even quoting as "Are you comfortable? Well it doesn't matter considering you'll be vaporized before you know it," when she was about 4 ft away.
Plot hole: When Marty lies on the conveyer belt on the way to the stone crusher he tries to wiggle off the belt. The little he seems to be able to move is not justified by the way his hands and feet are tied up. (01:08:30)
Plot hole: When Melanie goes to meet Jake at the beach, it is pouring rain. Her hair is soaked and her dress is wet and muddy at the bottom. When they arrive at the wedding reception, her hair is much drier and her dress is perfectly dry and clean. (01:38:25 - 01:41:40)
Plot hole: The psycho coed murders her lecherous professor (played by William Shatner) by pushing him out a window. In the very next scene, she's driving around with his body propped up in the passenger seat of her car. She weighed no more than 100 lbs., tops, and Shatner was easily at least 250 when this film was made. No way she could have dragged him to her car and lifted his dead weight into the seat, no matter how much adrenalin she was pumped with. Physically impossible.
Plot hole: Contrary to the realism of developing a video game Alex should have had external files such as character models, stage maps and coding on his laptop which he could have used as evidence that JP stole his game, It would be impossible to keep all of the games files on one disc especially if he wanted to change something in the game because if you want to modify a DVD-RW you have to erase the disc data and reburn it.
Plot hole: Calden would almost certainly not be allowed into the autopsy room without some protection: a facemask, goggles, gloves. Not only to protect from errant bodily fluids (as we saw) but also to protect from any infectious diseases those fluids (or any escaping gasses) might carry. Also, he runs the risk of contaminating the evidence.
Plot hole: It's amazing that the two Chapman women weren't caught at "Rock for Daddy Day Care". One of them unzips a guy's dog costume in the middle of the path with everyone walking by. A little kid actually stares right at her when she does this. Also when Jenny puts the cockroaches in the salad, the people who were waiting in line for food would definitely have seen her. There are many more parts like this.
Suggested correction: And yet this kind of thing happens in real life too. Where somebody goes around causing a ruckus in a crowd, people around see them, but they say absolutely nothing and let them get away with it. It's called the "Bystander Effect," where people don't want trouble, so they assume somebody else around will do something. The encouragement of "See something, say something" comes from this exact thing. If it happens in real life, there's no reason it can't happen in the movie.
Plot hole: The main criminal puts on the "butt inspection gloves" whilst searching the first house, but when Alex sees him through the telescope he pulls down the blinds and has black gloves on. Returning outside, they revert back. However, how does Alex know the criminal donned the rubber gloves (when he describes him to his mother), if he saw what we saw through the telescope - the black gloves?
Plot hole: How would Arnold know about the cop hitting the bus when he was running away from him during the parade? He was far past him at that point.
Plot hole: When Gwildor tells Julie and Kevin that he can use the Cosmic Key to take them to any point in time they wish, Kevin asks just for them to go straight home. As Kevin and Julie go through the portal, Julie turns around and shouts to Gwildor to send them back before being dragged through the portal completely. When Julie wakes up in bed, she discovers that Gwildor has sent her back to the day her parents were killed. Julie never said where in time she wanted to go, so there's no way Gwildor could know to send her back to the day her parents died.
