Continuity mistake: In a scene early on where Mike is behind the video shop counter and Jerry is in front of it, the positions of the videos on the shelves behind Jerry alter from shot to shot.
Audio problem: When Chase pulls out the key to MSA, you hear the sound of many keys clanging together. However, if you look closely, there is only one key on the ring.
Revealing mistake: In the final shootout scene, when Rambo takes over the truck mounted machine gun, he shoots the driver, whose blood splatters a lot over the metal guards on the gun. If the blood splattered that much on the guards, it should be all over the interior of the truck which is revealed to only have blood on the floor - none all over the dash or doors.
Continuity mistake: When Prof. Rosa calls Cole, Terry answers the phone and places Rosa on hold. However, when Cole takes the phone from Terry, he does not take Rosa off of hold and proceeds to talk to him.
Continuity mistake: When the guy walks in on Peter naked in bed, the sheet protecting Peter's modesty is covering him in one frame, and the next moment it has vanished completely.
Revealing mistake: In the scene where Big and Carrie meet in their cars after Big fled the wedding you can see down the street in the distance a huge amount of SATC fans have gathered to watch the filming. (00:52:35)
Visible crew/equipment: When Donna is telling Tanya about Sophie's dad arriving, stage lights can be seen in Donna's glass.
Factual error: After the boat has blown up and sunk, Ben swims over to it and checks it out, very little to anything is even a little charred, with that big of an explosion everything would be burnt, and black.
Continuity mistake: In the scene where Hogsquel gives Jared "the sight", after he spits in his eyes Jared is holding the seeing stone, but in the next shot when he is wiping the spit from his eyes the stone is gone.
Factual error: At the end we see a soldier replacing the canister that the Zyklon B is kept in. However, he is not wearing an SS badge as all SS soldiers did. Zyklon B was only handled by members of the SS, as no other unit had authorisation to carry the sensitive stuff. (01:28:00)
Other mistake: When Dennis Quaid fires his SIG-Sauer P229 pistol on the bad guys under the over-pass, he fires 28 shots from a 10-12 round pistol without reloading.
Visible crew/equipment: When Alison and Sidney are walking together on the street after a party, they cross the water and the shadow of the cameraman and the camera itself can be seen on the wall behind them and then again on Alison's face.
Continuity mistake: In the scene where Zeke and Charlie are running back to the vortex, Charlie's goggles move from being on his left side to behind his neck to his right side. The goggles keep moving back and forth.
Factual error: We see Jason Statham walking into a shop in 1971 which has a Visa/Barclaycard logo on the door. Only problem with that is that the name Visa wasn't brought in until 1977.
Factual error: There is no possible way to cause a power line to drop from its support pylons and hit a person on target. These wires are fastened extremely securely, designed to withstand extremely high tension through all kinds of weather, and they are not equipped with some sort of explosive charges to release them.
Continuity mistake: When Harold and Kumar arrive in Texas, the rear license plate on their car is a Texas plate. The car's front plate is from Virginia when they are in front of the whorehouse. The rear plate changes back to Virginia once they get to the house.
Plot hole: The FBI in the movie has the ability to "blackhole" an IP address, which makes that computer unavailable to the internet. If they can blackhole the computer acting as the web server, they could also blackhole the computer acting as the name server (DNS), thereby taking down the web site and preventing additional users from connecting.
Continuity mistake: When Katherine Heigl and her sister are having a fight, her sister throws a portable phone onto the couch. The phone goes from just being visible behind one of the cushions to completely vanishing a few seconds later after the "Bridezilla" rant.
Factual error: In the scene when everyone is in the white Hummer, the vehicle is moving north on the Las Vegas Strip; on the right is Bally's and the Flamingo, with Treasure Island straight ahead in the distance. Yet a few seconds later, when Joy asks the driver to let them out, they are in front of the fountains at Bellagio, which indicates that they are now travelling south on the Strip - yet we never see the Hummer change direction or turn around.
Factual error: Outside the Territory Hotel, during the storm, and once earlier in the movie, the taxi cabs are shown with the modern "flip over" vacancy/hired signs that were not used then.
