Revealing mistake: The Red Queen tries to goad Alice into killing Rain in the laboratory, with the Licker pounding against the glass outside. Just after they escape the room, the Licker breaks in. Watch its jump very carefully. you can see the exact invisible "line" where the Licker stops being a guy in a suit and becomes computer generated. It even changes colour. (01:20:45)
Continuity mistake: Near the end of the film, on the train ride out of the Hive, Rain is quite close to becoming undead. When she speaks, we notice her teeth are still "movie-star white". However, a few shots later, when she becomes a zombie, she sort of hisses where you can see it has taken what couldn't have been more than a few mere minutes for her teeth to become brown and discolored. (01:21:00)
Continuity mistake: When Matt gets scratched by the mutated Licker at the end of the film, the scratches on his arm appear before the creature's claws actually hit him. (01:24:15)
Continuity mistake: Shortly after the Licker pulls Kaplan out of the train, Matt shuts the door so it can't get at the rest of them. The Licker goes on the roof to use the back entrance to get into the car. Matt hears this and rushes to bar the back door. Pay attention to the near dead Raine. She suddenly gets a lot more life and quickly moves out of the way to avoid being accidently trampled. (01:24:55)
Revealing mistake: When Alice hits the first person in a biohazard suit, the padding is visible on the chest section. (01:25:40)
Other mistake: When the train arrives back under the mansion from the Hive, it enters the station from the wrong direction. Looking at the track from the platform, the train comes in from right to left, when it should be from left to right. (01:27:20)
Continuity mistake: Alice wakes up at the end and is completely nude with the exception of some paper taped to her front. We see when crawls under the bed that this is the case. However as she is cocking the shotgun in the streets the wind blows open to the doctor's jacket she put on earlier, but it also shows that she is now wearing white underwear to hide her modesty in case of a mishap with the wind. (01:30:00)
Factual error: The case containing the virus requires a four digit code to open it. As demonstrated by the operative that opened it to give himself the antidote near the train. Yet Alice closes the case, and later opens it without entering a code.
Continuity mistake: At the start of the film, the scientists are attempting to breach the window with an axe. Later in the same lab in the movie, Alice picks up an axe, even though it was shown before being wielded by the zombie.
Chosen answer: The winner was the English girl playing the Red Queen.
