Corrected entry: When everyone is in the laser room, and the medic woman gets the laser through her neck, the injuries that other people got didn't bleed because the wound was cauterized, yet her neck bleeds a bit before her head falls off. (00:32:40)
Corrected entry: In the room where the lasers attack the crew you can clearly see that on each end of the room there is an extra space that is away from the small hall where the lasers cannot reach and it is clearly enough room for them to stand and not get killed. (00:31:07)
Corrected entry: When Kaplan and Alice are walking across the pipes in the sewer area and Kaplan falls down, Alice is pulled up, and Raine has her gun out, trying to help Kaplan. She is aiming her gun to everyone's right, and everyone was looking in that direction. When Rain yells out that she can't see, Alice takes the gun off her and shoots the zombie nearest to Kaplan, aiming the gun to everyone's LEFT, meaning that Raine was aiming in the wrong direction. Even if she couldn't focus properly, everyone was looking in the other direction, too. (01:05:35)
Corrected entry: In the shot at the beginning of the scene where they are in dining room B, the guy wearing the handcuffs manages to get on top of a high edge and sit on it with handcuffs on .. (00:29:15)
Corrected entry: It says this on the commentary on the DVD, but in the scene where they are on the pipes you can see the camera rail above them, but they are supposed to be made to look like pipes. (01:04:05)
Corrected entry: Several times during the train sequences, and on the schematics, we see there is only one track between the Mansion and the Hive. So on the return journey, the train should be travelling backwards, yet it is going forwards with Kaplan in the cab on both occasions. From the interior and exterior shots, you can see that it does not have a cab at both ends.
Corrected entry: In the dining hall B part of the movie, the guy fires 8 shots out of the same revolver and you can clearly see there's only 6 chambers.
Corrected entry: Alice & Matt arrive in the control room via a corridor from the office block, apparently being chased by zombies. This is a different corridor than the one Rain, Kaplan & Spence entered via. (You can see the two corridors on the heat-tracking schematic that pops up during this sequence). If that corridor was clear ahead of them, why didn't the three already trapped escape up it? If there were zombies outside that door, then Alice & Matt managed to get through them without too much trouble, so could the others. (00:53:35)
Corrected entry: In the scene in the laser corridor, when the woman has her head sliced off, why does she look around first, and not drop when she is told to by the commander. All soldiers are trained to do any commands like 'Down' when they are said, so that they do not waste time looking around and then dying or getting hurt.
Corrected entry: During the laser cutting sequence, a blond-haired team member tries to avoid the lasers by jumping over them and gets sliced through his waist as a result. As soon as this happens he lands on his feet once, then it cuts to a shot of his face and we can see he's landing from the jump again.
Corrected entry: The leader of the team sent into The Hive has a G36 assault rifle with a grenade launcher underneath. If you look closely at the gun, it was cut in half to make it look futuristic. He holds it by the grenade launcher instead of the actual grip of the gun.
Corrected entry: When there is a slo-mo camera shot of the bullet case falling to the floor, it doesn't bounce, it just sticks to the floor.
Corrected entry: When Milla wakes up in the shower at the very beginning of the movie, she's been lying on the floor in the shower. However you can see her hair is totally dry and perfectly made up, if she had really been lying on the floor for more than few seconds, she would be covered in drops of water which would have been landing on her (even though she's not lying directly beneath the spray, she would still be covered in water, if you have a similar shower, you could try it yourself) (00:08:25)
Corrected entry: In the scene where the group first come across the zombies, they back towards a locked door and try to hold off the attack. When they manage to open the door they are confronted by an even bigger horde of the undead and one of the marines is eaten alive. The rest manage to shut the door and go back the way they came. The problem being that they were just running away from there - where did all the zombies go?
