Plot hole: The whole problem with the teleporter occurs when fly DNA is mixed in with Seth Brundle's DNA, starting his transformation into the Brundlefly. Brundle is on a hiding to nothing from the word go, and the fly is irrelevant. Humans are a walking talking mass of foreign DNA - we are host to one trillion bacteria all of which has a complete complement of DNA, as do various tiny mites that live in our hair follicles and all sorts of single cell organisms in our gut. If the transporter serves to mix the DNA of all living creatures which are in the transporter pod at the time Brundle would turn into a half-man, half-bacteria. Incidentally, DNA from a bacteria, an amoeba or a hair follicle mite would be just as 'compatible' with human DNA as that from an insect. It's quite a simple chemical, really.

Visible crew/equipment: When Freddy falls over the banister onto the stairs near the end, notice the crash mat he lands on. (01:18:55)

Other mistake: The first time the cops come to the house, Connie and her son see them from the upstairs window, and start walking downstairs. It then cuts to the cops in the living room looking around, and Connie walks in and introduces herself. Her husband is not home, so did the cops just walk into in the house without knocking?
Suggested correction: I'm pretty sure the housekeeper let them in if you listen carefully.

Other mistake: The construction of a staircase does not require a large nail at the site shown on the steps. Furthermore when Emily snags her clothes basket on the stairs it lifts a small nail up. How did it grow into a 2 inch fat nail?

Continuity mistake: When Blair asks Mitch "why aren't you answering me?" he says he got a weird message from Laura Barns. Blair replies "that's not funny" and Mitch replies "I'm serious." Then Blair gets a message from Laura, and when she switches back to Mitch's conversation, the last two entries, "that's not funny" and "I'm serious" have disappeared. (00:10:50 - 00:12:30)

Plot hole: The snakes escape from the locked box stored in the cargo hold when a small explosive bolt detonates and opens the lid. Post 9/11 all luggage placed in the cargo hold of an airliner would be tested for explosives, and anything larger than half a match head would be detected. The chances of getting an explosive bolt on board - nil. None whatever. You can also think of it this way - if the bad guys could somehow smuggle explosives on board, why bother with such an elaborate and flawed plan as letting snakes loose on the plane? Why not just smuggle a bomb on board? Pan Am 103 - the so-called Lockerbie flight - was brought down with a bomb that fit inside a small cassette player.
Suggested correction: They wanted to make it look like an accident. If the snakes had done their job fully, plane crashes and no-one is the wiser. If the plane blew up halfway it would have screamed foul play. As it was in the movie it was just a terrible accident, a bunch of snakes being shipped got loose.
That doesn't correct the posting. The error is that they could not have smuggled a package equipped with an explosive bolt onto the airliner in the first place. It would have been detected and the package removed from the airliner and either defused or safely detonated. As for nobody being the wiser after the plane crashes, what were all those dead snakes doing scattered about the wreckage?

Continuity mistake: In the scene where Ruby and brother are driven to Terry's crash site the police cruiser changes from a 98 model to a 97 model. The vehicles headlights, front bumper and over all design are completely different.

Continuity mistake: In a scene towards the end of the movie where Bond and Vesper are lying on the beach, Bond has sand on his back through most of the scene. When they start to kiss, in the distant shot towards the end of the scene, he has no sand on his back at all. (01:57:10)

Continuity mistake: In the scene at the bar with Gideon when the black guy pours Gideon a drink it is only about 1/3 full. When Gideon drinks it in the next shot it is almost full.

Visible crew/equipment: You can see the string that pulls Bubba off the bike when Max shoots him. (01:19:41)

Factual error: When the house explodes, there is a massive explosion and fireball that creates a pressure wave strong enough to send Brian flying into the van. However, not a single window breaks on the houses just feet from the explosion. (00:15:40)

Continuity mistake: Nick Cage is chasing Mason in the yellow Ferrari. The windshield breaks at least twice, but is perfect in the next shot. (00:45:55)

Factual error: When the Titanic sinks all six dwarves and Kevin end up in the sea clutching a lifebelt. The water in which the Titanic sank was freezing - that is how most of the casualties died, by freezing, not drowning. In water like that you'd be lucky to stay conscious for more than a few minutes. Despite this none of them show the slightest effect of the cold. Maybe the dwarves have some 'magical' ability to withstand lethal cold, but Kevin doesn't even react to being plunged into freezing cold water. He'd be screaming in pain, but he doesn't even show the slightest sign of discomfort.

Plot hole: Patrick Redfern needs someone to be in the boat with him to corroborate his and his wife's deception and be his alibi. That is whole point of his wife lying on beach - he gets this when taking Myra for a ride - but it was portrayed as a random ride she got, he did not intend or plan giving her a ride, he did not see her loitering near the boat, or even in view of him untying the boat. Even if that was intention in the story for him to be seen ready to cast off, the movie viewers did not see her viewing him, only her appearing just before he was set to cast off. Without someone with him the whole deception would not work, he would have no alibi, he could have killed Arlena unseen.

Plot hole: When Bridgette ran through the glass and Linda and Jim were at the hospital Jim tells Linda he called her mom and told her what happened and she was coming to stay over the next day. Yet apparently her mom forgot what happened because she had her committed because Linda didn't remember what happened to Bridgette's face. Also, Bridgette was like 9. How come no-one just asked her what happened?

Revealing mistake: When Loomis shoots the marshal's window out, when he makes a u-turn you can see the tire marks on the road and dirt from previous takes.

Revealing mistake: When Nica crawls to the elevator to escape Chucky, she bends her legs in order to shut the elevator door. She is meant to be a paraplegic and have no feeling in her legs.

Factual error: Their 'spot' for drinking is apparently in the French Quarter because of the street signs. That said, they are drinking Budvar beer. If you know about Budvar, it is the original Budweiser beer from the Czech Republic. Budweiser sued Budvar and won, preventing them from using the name 'Budweiser', even though Adolph Busch came up with 'Budweiser' after going to Pilsner, Czechoslovakia. Budweiser being the bully, and their lawyers and all, won the lawsuit. So now the beer is sold as 'Czechvar' in the US and 'Budvar' everywhere else, meaning they couldn't be drinking it in the USA.

Continuity mistake: When Sonic and Tails are fighting metal Robotnik, he shoots glue at Tail's tail. Tails says he can't fly to help Sonic, but when he gets the piece of concrete to surf across the water on you can see that his tails are not glued together.

Plot hole: The whole movie plot relies on a very unlikely assumption: that the ex-husband would not visit Kidman at her mental institution where he put her in, nor call for any news at all, for four whole years... Even though divorced, they still share a common child! And what about the parents / siblings / extended family/ friends of Kidman? Would they also never visit for four whole years? If any one of them had, then they would have known the (fake) ex-husband had taken her out and would have called the real husband to get news. Then Kidman would have been reported as kidnapped.
Suggested correction: Being as how the bacteria and mites and such were IN or ON Seth, the machine was able to organize those symbiotic relationships accordingly as teleporting one would teleport all. The fly was separate, not touching. The machine was not programmed to anticipate two separated entities and so combined them into one on the other side.
Phixius
We leave behind a vapour trail of bacteria and viruses (among other things) as we walk, in our breath and emanations from pores in our skin, and Brundle isn't trapping any in his clothes as he isn't wearing any. Brundle has an invisible cloud of DNA floating around him in that teleportation chamber and as far as the machine is concerned their DNA has exactly the same status as that of the fly.
