Continuity mistake: When Charles answers his cell phone after being in the bath, the hand holding the phone is wet and covered in bubbles. In the subsequent shots, his hand and arm are completely dry.
Continuity mistake: At the end, when Charlie is writing "As Wichita falls, so falls Wichita Falls" on the back of the RV, it shows him only making a couple strokes with his marker, only being able to write a few letters at most. In one of the very next shots, he is hit by the back of the RV as the driver, who is trying to start the engine, accidentally jerks the vehicle backward suddenly. Before he is hit, "As Wichita falls, so falls Wichita Falls" is written out completely. There is no way he would have had time to write all of it.
Continuity mistake: When Luke brings Caroline back to the house after knocking her out, Violet demands to know where Ben is. In this shot her tears are black because of the mascara, but in the next shot all her blackened tears have disappeared.
Factual error: In order to be electrocuted you need to connect a high voltage to a low voltage. Touching a power line does not get you electrocuted unless you make contact with the ground. So electrocuting the locusts by making them fly against a powerline can not work because they are not 'grounded'.
Revealing mistake: After Majid commits suicide, he is breathing.
Plot hole: The survivors find their way to the internet lounge to send out a message via email about the terrorist attack. The ship was upside down. All satellite dishes used to transmit over the internet were completely submerged in water. Even if there was power to the computers, they would not have been able to get a server connection let alone send out email.
Continuity mistake: In the kitchen scene at Greg Kinnear's house when Pierce is convincing Greg to fly to Arizona with him to do a job, the clock on the wall behind them first reads 5:45 am. In the next shot, the clock reads 5:28 am.
Audio problem: Just after the long continuous fight scene in the restaurant, one girl pulls out a knife to attack Tony Jaa. The knife makes a sound like it's being pulled from a sheath but it's not touching any other metal.
Revealing mistake: After Majid commits suicide, when he is on the ground, you can CLEARLY see him breathing. I mean, it isn't even funny how much you can see him breathing.
Continuity mistake: In the end of the movie, they show Henry being put into the ambulance on the stretcher. The next shot is of Sam and Naomi Watts's character and then another shot of the ambulance, where Henry's body on the stretcher is outside the ambulance again.
Continuity mistake: When Tom's car crashes against the water bottles, the crash causes a hole in the windshield. A second later it's fixed and perfect.
Factual error: The movie takes place during a single NFL season. In the beginning of the movie, when Brandon is still in Las Vegas, the paper he is using to pick games shows Seattle playing New Orleans. Later in the movie, still the regular season, Seattle and New Orleans are playing again. They would not play each other twice during the regular season.
Continuity mistake: During the song sequence of "Chham Se Woh A Jaye"(the wedding song), Abhishek Bachchan's dupatta keeps changing the way it is wound around. Once it is around his left shoulder, and once around his right. This continues throughout the song, whenever the camera focuses on him and Zayed Khan.
Other mistake: Otis picks up a DVD case and asks if he can take it home to look at. While waiting for an answer he opens the jewel case and even moves the inside flap (as would be in a case with more than one DVD). There is no DVD in the case, it is completely empty (all black inside). He later views the non-existent DVD at home. (00:16:55)
Other mistake: In the scene where the guys first fly into Newark, they are seen getting off the airplane after landing. When the camera pans around the back of the airplane there are orange gust locks on the rudder and elevator. The gust locks are used when parking the airplane overnight and would not be installed just after landing.
Continuity mistake: When Kelly Brook trips over the sofa in the hallway you see her fall and as she gets up you can see a blue thong, 00:07:24. Now when you see her later on in the film when she is sitting by the dining room table with Dennis Hopper eating when she gets up she is wearing purple lacy underwear 01:02:26. Later on when she is fighting the man with glasses from under the bed, when you see him pulling her legs in order to get her out from under the bed you see her wearing black knickers 01:19:32 or you can get a better shot at 01:19:33. Now all the characters of this film are supposed to be trapped and when they're kidnapped the clothes they're wearing should be what they wear for the whole film.
Continuity mistake: In the scene where they ask Tina about what went on while she was in the tunnels, there are several shots where you can see her right hand covered in blood. But when they show a close up of them cutting the same hand to see if she's infected by the fungus, you can see that her hand is slightly dirty but without a trace of blood.
Continuity mistake: In this scene we see the police car chasing Wesley Snipes' car. During the chase we see that Snipes' car has sustained heavy damage to both front doors, then when the car finally comes to a stop after the chase, it has repaired itself. The doors are repaired with only slight damage to the right front.
Other mistake: When they open the bag of money and fan through it, you can see the back bill says TWELVE - as in a twelve dollar bill.
Continuity mistake: In the deer scene the deer breaks the window but the next shot shows the window unbroken.
