Deliberate mistake: When Jim and Lauren are having their stargazing experience, it's clear that the pints of beer the monkey brings them are fake so that they don't get spilled.

Question: As many times as I've seen this movie, I don't understand how Pete comes to the conclusion that Miranda is not delusional in the end. We see him searching images of the tattoo she kept talking about, but I just don't understand how that would lead him to finally believe that she has been telling the truth. Can anyone explain this to me?

Revealing mistake: When Bella calls Rosalie, you can briefly see the cell phone screen before she puts it to her ear. The lock screen is still visible, showing she didn't dial anything. (00:55:45)

Continuity mistake: In the scene where the remaining survivors are on Steve's boat and Michael stays because he's bitten, the sun changes positions. It goes from being morning to afternoon.

Revealing mistake: When Victoria dives off a cliff to escape the wolves chasing her, her hair doesn't move at all, as if she's standing still.

Continuity mistake: After the spaghetti twister, Flint puts on his lab coat in the elevator and you can see he has his tuxedo shirt on. Then during the building montage, it's a blue shirt, then changes back to the tuxedo shirt when he turns on the car. Also, during the building, the design on the blue shirt disappears.

Question: Why does Alice dance briefly at the end after returning to the regular world?

Continuity mistake: When Derek gets the New Year's e-mail from Lisa and he starts closing out the pictures, it shows the screen where he closes out all but two pictures. Then it goes to his face and back to the computer where it's gone back to three or four pictures.

Revealing mistake: After Korban meets Ruby and everyone leaves them alone, Korban grabs Ruby by the neck and holds him to where his feet can't even reach the ground. In the first shot, you can tell that Korban's hand isn't even applying pressure. In the next few shots of Ruby, still being held off the ground, you can now see that Korban's applying a little pressure now, but probably not as much as there should be while holding a full grown man a foot off the ground.

Factual error: When Grady and Earl are trying to sleep on a boulder, there's a very large moon in the sky. It's clear that it isn't the actual moon. None of the craters or other markings correspond.

Other mistake: When Anne and Nicholas are trying to sleep and Victor keeps opening the curtains, Anne gets up to close them, and then you hear Victor run across the room and open them again. However the silhouette that is supposed to be Victor opening the curtains appears to be Anne's. You can plainly see her longer hair, and when we see Victor in the end, he has a very short haircut.

Sammi

Continuity mistake: When Anna is explaining what the symbol on the building means to Rose and Cybil, she hoists her bag of supplies over her shoulder. In the next shot, she's gone back to holding it in front of her. Then, over her shoulder again in the next shot.

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.
