Plot hole: After his mother's death, Peter sets a camera up outside her therapist's office, so he can see who goes in and who comes out; he thinks his mother's killer might be one of the doctor's patients - a tall woman with long blonde hair. All he sees is people going in and people coming out, and then he sees her - the tall blonde. Problem: He never saw her going in, only going out, which is critical, because the killer is the therapist - a tall man - wearing a long blonde wig and make-up. Of course no-one says anything about "We never saw her going in, only out, so it must be the therapist!"
Plot hole: Richard eventually manages to travel back in time by removing all the modern items from his room. But what about the spotlights above his bed? (00:31:40)
Plot hole: While still unsure where and when they are, the Nimitz has two F-14 Tomcats aloft, investigating a pair of low-altitude radar contacts. They determine the planes are WWII-vintage Japanese Zeros in full military livery. The Tomcats are told to shadow the Zeros without engaging them. Then, the Captain, the XO, the CAG and Lasky all go to a formal dining room and sit down to tea. In this scene, they talk about many other 1941-era things that are happening, but nobody mentions the Zeros. That fact, and that they left their Tomcats where they did, suggests this scene was meant to be in an earlier part of the film (when things seemed odd, but no imminent threat existed) and got moved here, creating a plot hole that the USS Nimitz could slide through sideways. US Navy nuclear carrier command staff wouldn't simply go have tea under the current conditions. (00:40:30)
Plot hole: When the fog finally hits the lighthouse and is seeping in, the generator is hardly audible vs. how loud it was when it was first started.
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: Kane and Irons abandon their horses to hook a ride on the train, leaving behind their rifles. When they get to Hadleyville, Kane has somehow reacquired his Sharps.
Plot hole: During the war games when Judy's squad captures the SGT. Outside red headquarters they demand the ignition key to the Duece which the SGT. promptly throws into the bushes, and the criminal hot wires the truck. Military vehicles are not started with a key they have a starter switch if you want to lock the vehicle you padlock the steering wheel.
Plot hole: The film takes place around 1980, i.e. when it was filmed. But Steve Railsback appears too young for the Vietnam veteran he is playing, and in any case he has meant to have come back from the war, immediately committed a crime, and been on the run since. This would only be possible if he had been on the run for a decade, with the police in hot pursuit for all this time: that is extremely unlikely. These inconsistencies are actually a reflection of the fact that the film was scripted a decade before it was shot.
Suggested correction: Cameron is not too young for the timeline of the film. Steve Railsbeck was born in 1945. The first US troops arrived in Vietnam in 1965. If Cameron did a one year tour of duty between 1965 when he was 20 and 1969 when he was 24, that gives him a year to be discharged, return to the USA, commit a crime, and be on the run for ten years or more by 1980. Wikipedia lists 120 criminals who have been on the run since 1970 - and that's just the famous ones.
Plot hole: Never in the film do the police try to stop the teams from causing havoc. There is really no way Leon has that much influence in the game. In fact, the only authority figures who really try and stop them are the security guards at the Bonaventure Hotel.
Plot hole: The six-year-old girl (who actually looks a few years older) apparently had seen and remembered a tattoo on the robber's hand well enough to be able to relate the details of it to Meredith, who is then able to visually identify the tattoo on the robber's hand in a strip joint. Not really credible - especially as the woodpecker costumes covered up pretty well the entire body! (Also, the robbers were constantly moving, making visual inspection even more difficult).
Plot hole: Antoinette Lilly makes headlines as being murdered and her husband is charged and sent to a criminal asylum...despite the fact that no body has been found and no one has even bothered to go to the hotel or town she was last at to investigate whether or not she's alive or dead. Not believable.
Suggested correction: John was framed by Antoinette's step-mother (who stood to gain Antoinette's inheritance). People have been arrested for murder without a body being discovered first though. Additionally, we find out that the lawyer who helped framed John also paid him to confess to the crime and admitted to being mentally unstable. So nobody was even trying to look for Antoinette.
Plot hole: When the gang goes to retrieve all the cars from the guy living in the desert they determine they have enough cars for a a one car safety limit. As they discuss this Jim is measuring the length of the blue car Jeff will be driving but the license plate of that car is never taken into account when being measured, so they should have already known that even with enough cars in their possession they didn't have enough cars to make a mile.
Suggested correction: They had a one car 'cushion", but it wasn't the blue Mercury, it was the car on the trailer the Jeep was towing. They had just enough with the Mercury, but he crashed it coming into the parking lot which shortened it ; the plate falling down added the extra inches.
Plot hole: The show is about a NYC high school for the performing arts. Yet many scenes including the piano composition rehearsals, feature way older adult students in their 20s, even 30s.
