Revealing mistake: Just before the Axeman throws his axe at Claire and Alice, we get of shot of Claire turning around. But pay close attention to the wall behind her. You can already see the crack which is going to hold up his axe before he throws it. And it isn't an old crack, because when Alice is about to take a shower, all the walls are perfectly fine.

Revealing mistake: After Bennett takes off, Luther jumps on the edge of the prison. When he hits it, you can see the seemingly solid concrete edge wobble.

Revealing mistake: When the Umbrella guards are lining up in front of the elevator, we get a few close-up shot of the level counter. During those close-ups, you can see the ribbed rear wall of the elevator when the dial is still only at level 3. Compare the wall to when the doors open, it is exactly the same. This means that the elevator isn't moving at all, and that it is just the dial. (00:07:05)

Revealing mistake: Just after the Tower Swing, Alice shoots with her Smith and Wesson at a load of zombies. But when she fires the last two shots (the ones in slow-motion) pay close attention to the gun in HER right hand. The chamber doesn't start to turn until after she has fired the shot, meaning that the hammer would strike a spent bullet.
