Plot hole: If Jack can speed the train up at the end, why does he not try to slow it down? Even if it can't be stopped completely, using the speed lever to reduce it to the minimum possible would be a sensible course of action. There is nothing to suggest he wouldn't be able to do this as he is able to increase the speed without any trouble. If there was something to show that slowing down the train would be unworkable it would make sense, but seems to more serve as a plot device.
Plot hole: When the warden comes into the cell the morning after the escape, the poster covering the hole is fastened down on all four corners - impossible to do after squeezing into that small hole. [On the DVD commentary, the director confirms that this was a movie "cheat".] (01:49:05)
Plot hole: In the Cowboys' last possession of the final game, Spike makes a long run before being stopped on the goal line. The Cowboys' next play is a run up the middle. The Little Giants stop the run and the Cowboys lose possession, but since that was the first possession of a new set of downs, the Cowboys would have three more chances to score.
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: The premise of the entire movie's main character, played by Jeff Bridges, is flawed, as it would be impossible for anyone to pass a major metropolitan police department's pre-employment screening background investigation for the position of police officer if that applicant uses a fake name and identity. Part of the investigation includes sending off the applicant's finger prints to the National Criminal Information Center, a polygraph test, a records check with vital statistics to verify place of birth, Dept. of Labor to verify past employment, Social Security Dept. and also interviewing (sometimes in person) your friends you've listed and your current and former neighbors of where you now live and use to live.
Plot hole: How does Clifford, a ten-year-old boy, manage to steal a stereo, a surfboard and a dog from the airport without being caught?
Plot hole: When Lalaina is in her depressed "Bell Jar" phase, she's complaining to the psychic hotline counselor that she's freaked out by the idea of having kids because she "can't even take care of a Chia Pet". But earlier in her documentary, she'd talked about how starting at age 13 she had to become the responsible one, buying food, taking care of and parenting her siblings. Which contradicts the portrayal of her as someone who can't take care of anything.
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: The reason given for the cop having psychic powers is that he has a well-developed hypothalamus - but that is the part of the brain responsible for homeostasis (maintaining a constant internal environment for the body). So even if you had a particularly well-developed one, you might sweat more when you get hot but how could it make you psychic?
Plot hole: When Juliet and David spend some money, they are seen watching a tape of the footage they filmed with a new camcorder. When Alex is in the bath, we see him with the camcorder (it is not a reflection in the mirror) - where did the second one come from?
Plot hole: When the 3 ninjas' Grandpa is in hospital, he phones them and complains that no-one at the hospital speaks English. Not only is this a strange complaint to make about a hospital in Japan, but later in the film he is seen speaking in Japanese. He should therefore be able to easily communicate with people at the hospital.
Plot hole: In the World Series game at the end of the movie, the scoreboard shows that the game is scoreless up until the very end. But Brendan Fraser is portrayed as an amazing phenom who hits home runs every single time he comes up. He obviously failed to hit a home run the first few times up in that game.
Plot hole: When Reggie is interviewing Mark in the hospital, she tells him that she will pick him up tomorrow about 2:30 for a 3:00 meeting with the FBI. But the next day, Mark comes running into Reggie's office after the attack from the hitman the night before, and she asks him what's wrong as if she hasn't seen him yet. The FBI shows up just seconds later.
Plot hole: Towards the end of the movie, Leon dies and Mathilda heads to see Tony. Tony gives her some spending money and tells her to get back in school. The nighttime scene suggests that she spends at least part of the night wandering the streets. Presumably at daybreak, she takes the tram car and returns to The Spencer School, where she talks to the school administrator. When the administrator asks Mathilda to tell the truth about what happened to her, Mathilda says in essence, "... I lived with the greatest guy. He was a hitman, the best in town. He died this morning..." This morning? Seems more like roughly 24 hours have passed since Leon died, so what Mathilda says is inconsistent with the scene sequence. (Special note - this is from the International/extended DVD edition. I can't say whether this exact sequence is in the shorter domestic DVD version.) (02:06:03)
