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: When the "black diamond" is being turned into its dangerous form, the arms dealers get very excited. Yet all they actually see is a very pretty laser show. There is nothing to show that the object really has any destructive power. Arms dealers make their fortunes by being cautious and smart. They shouldn't be so quick to accept the claims of the bad guy and bid money on possibly useless stones. (01:18:20)
Plot hole: James Bond shouldn't have gotten away at the end of the airport scene, where he steals an aeroplane and pretends to be a flying instructor. He had no wings with which to fly away, and he ended back up right outside the airport. So, the henchmen, who seemed to still be chasing him one shot before he parked, should have been right on him, waiting when he got out of the plane.
Plot hole: Bond goes after Lupe after she leaves the casino table, and they have quite a lengthy, hush-hush conversation. It's a casino, and there are cameras everywhere. Certainly, this would have been brought to Sanchez's attention since he was already leery of Bond and possibly Lupe.
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: Referring to that blackout night. How come the group can actually film how they put all their cameras and stuff into its hide?
Plot hole: In the lobby of police headquarters, Danny Roman's lawyer tells him to make a deal with the prosecution. Danny turns to his wife Karen and tells her to wait in the car and he will be right back. Then he proceeds to go upstairs and overtake Niebaum's office. Much later when Chris Sabian is negotiating, Karen arrives on the scene wondering what's going on. How long was she waiting in the car? (00:28:35)
Suggested correction: This isn't a mistake. Karen (and anyone else still on the property) would have been sent away by the police once they became aware of the hostage incident. She went home to wait for Danny because she doesn't know he is the perpetrator. When she is called back to the scene by Sabian she wonders what is going on because she doesn't know that Danny has taken hostages in the building.
So she drove there with him and then just leaves him there? Lol. Can't see her just leaving without him since they drove there together. Even if people went around telling everyone to leave the area, I just can't see her not hanging around and waiting for him.
Plot hole: Towards the end of the movie when Michael Douglas makes his speech at the White House, he is able to quietly walk out of the gates with no reporters anywhere trying to chase him down. Totally unrealistic (especially considering what had just happened). (00:03:03 - 02:13:40)
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: When John is painting the doll's face he looks down at a photo printout of Amanda, you will notice the bruising/scratches on the side of her face in the picture. Please take note of her hair, shirt and overall demeanor. Now think back to the first Saw when Danny Glover had Amanda in the interview room. The picture that John Kramer is looking at is a picture taken of her in "that exact" interview, this is strange however considering that the interview took place after she escaped the jaw splinter, so how does John have a picture of her from the future? (00:51:40)
Plot hole: Hoffman is able to implicate Agent Strahm as the mastermind behind the main series of traps in this film by planting Strahm's cell phone at the scene. However, Hoffman is repeatedly shown to be touching things at the scene without wearing gloves, so a forensics sweep of the crime scene afterwards would show Hoffman's fingerprints all over the place and reveal him to be the actual mastermind. Agent Erickson arrives at the crime scene before the two survivors of the traps complete their tests, so the forensics team would have been called in before Hoffman had a chance to remove any evidence that would incriminate himself. As a forensics officer himself, Hoffman should know better.
Plot hole: Enola and Tewkesbury make an unpremeditated decision to visit the Basilwether estate. This decision was made on the spur of the moment, and no-one knew about it. but when they arrive, Linthorn, who is supposed to be in London looking for Tewkesbury, is waiting in ambush to kill them. (01:32:45 - 01:34:31)
Suggested correction: Linthorn saw them in London. He travelled back to the Basilweather estate, and waited for them to slowly make their way there.
Enola and the young Tewkesbury were in London two weeks prior to Enola's forced enrollment in a boarding school where she was supposed to spend her next few years! Furthermore, there is no evidence of Linthorn having seen them.
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: When Kale and Ashley escape from Turner, Kale tells Ashley to make sure the police come. But, when the cop comes, Ashley does not seem to have told him about what just happened, he gets killed before he can request backup, and then the police arrive right after Kale and his mother walk out the garage after defeating Turner. Why did she not inform the cop and wait all that time to call the police?
Plot hole: How does Agent Lahiri know that you needed to raise the pylons before it was possible to make the cross bow shot the boys needed to unlock the house in Amsterdam? Additionally, those pylons would not be accessible through water as they are planted in mud under the foundation of the building, not water.
Plot hole: When the innkeeper is asked by the rich ex-actress to give her the key to a nice room, he gives her a key telling her that eight is cozy and the key has an 8 on it as well. But a few minutes later, when this woman is about to be murdered, she leaves her room (holding her mobile phone) and the door has a 9 on it. How can a key to the room 8 open the door of the room 9? [Still a mistake, but there's an explanation. In the DVD extras you can see a deleted scene in which she changes rooms because she wasn't happy with 8.]
Plot hole: When Gawain is repairing the hole in the vault wall, a security camera is visible in the top corner in the room.
