Plot hole: About half way through the movie, the basketball coach is in his office and you can see a dry-erase board behind him, and a couple of dates such as 3-15-99... however earlier in the movie when they are announcing the basketball game they say that it is the 2000 season. They obviously changed the voice over to 2000 after the release date was changed, however the dates on the board are still referring to the scheduled '99 release.
Plot hole: Eric and Shelly were killed because they were trying to fight tenant eviction. Yet, a year later the building is seemingly abandoned. Eric and Shelly's stuff is even still there. So what were they killed for if nothing was ever done with the building?
Plot hole: In the scene after Chris' disastrous lunch date with Caroline, he is seen signing autographs before getting into his limo; however, he starts making out the autograph to Amber before he has even asked her name. He tries to cover by then asking for her name, and acts surprised/shocked that it is indeed Amber.

Plot hole: When Daniel is in the air with the stolen plane from the Los Alamos air base Nat suddenly appears from behind. However, Nat had no chance to slip into the plane secretely as there was only one stepladder that had been in his mom's full view while she hugged Daniel good-bye. (01:25:30)
Plot hole: When the police search the white car and the barn they fail to find the compartment in the car behind the boot in which the decoding equipment was hidden. This is completely improbable. It was a standard car, the compartment was not a secret add on, and the police were supposed to undertake a thorough search of everything.
Plot hole: In one scene, he's driving from Los Angeles to Berkeley in a hurry, and crosses the bridge again (in the wrong direction). But the most direct route from L.A. to Berkeley doesn't require you to cross the Bay Bridge in EITHER direction.
Plot hole: In the runaway train scene, Gene Wilder uncouples the train from the forward car, and has to make a dramatic leap to get back to the uncoupled car. Is there any reason he couldn't have uncoupled the train from the back car and just stayed put? It seems an unnecessary bit of drama.
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 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: 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: Modern diabetes management will tell a patient immediately if their glucose levels are out of the ordinary. Results are not monitored and delivered to a county jail by an outside lab. If a diabetic is sick enough, they would have obvious physical indications. The entire escape plan hinges upon these fallacies.
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: When the first police car arrives at the observatory, the policeman there tells them that the kid (Plato) holed up in the observatory has a gun and had "wounded a kid earlier." However, when that same policeman arrived at the mansion, he and his partner only ran into Plato and then followed him to the observatory. He had absolutely no way of knowing what had happened at the mansion prior to them getting there, which is when Plato shot one of Buzz's buddies.
Plot hole: At the end of the movie when getting out of the bear pit, the crew decides to use a ladder when a set of stairs can be seen. Was this so Vince Vaughn could give his respect speech?
Suggested correction: You forgot to mention the stairs are also in the bear cave and there's no guarantee they lead out of the pit.
