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: 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: 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: 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 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: When Forrest finds out he is receiving the Medal of Honor, he is addressed as PFC Gump (Private First Class, E3). "Two weeks later", he leaves Vietnam, and is then shown receiving the medal from President Johnson. In this scene, he is wearing Sergeant's stripes (E5). There is no indication or mention of him receiving a promotion, let alone two. (01:02:10 - 01:03:05)
Plot hole: By the time Lloyd gets to the airbridge the plane had already left. The finalisation of the boarding process after last call, plus push back takes at least 15 minutes. Lloyd would have easily caught up to Mary or the plane would have still been there.
Plot hole: After the robbery scene, the partner sends in the other cops and says that there is another one inside. How did he know this? No one told him, and the other robber was obscured by shelves in the door so he could not be seen.
Plot hole: There is a scene setting up the nonsensical resolution of the plot, when the policeman recaps the various baby sightings. First; he already got 'fake' reports he chased, there was a scene about that, let's ignore the fact that certainly he would have gotten more like that and he conveniently for the plot lists just the few relevant ones. Second; the baby was kidnapped at 10 and the baby sighting on the bus happens "in the morning." Then the zoo sighting happens "at 3 o'clock." The construction site closes at 5 o'clock. Even forgetting the superior stamina of the 9 months baby that has been walking a whole day without a break, that's a lot of stretch for the actions as shown in the movie, in particular the time between the bus and the zoo; the bad guys would have been loitering in search of the baby for hours between the bus incident and the moment when he leaves the department store to get to the zoo.
Plot hole: Harry goes into the Mall, and two of the terrorists follow him through the Mall, up the escalator, down the hall, and into the men's room. Then the third terrorist leaves the car and follows exactly the same path to where the other 3 went, even though there's no way he could have known exactly where to go.
