Continuity mistake: Kim Yong is killed in the shower block and his corpse falls to the floor but is never seen again. (01:02:30)
Other mistake: During the fight with the Axeman, we get a few shots of him breaking the shower columns. In the overhead shot of Claire, the columns in front of her and way out of reach of the Axeman are already broken, before the flip. (01:03:00)
Factual error: Just after Alice jumps from the tower and draws her dual revolvers, the film slows down to bullet time to show her shooting two zombies. If the speed of the bullet is accurate, there's no way she can move so fast as to then run and get out her shotguns. (01:03:40)
Continuity mistake: In the scene after Alice bungee's off the roof, as she runs through the crowd of zombies towards Luthor, she fires the shotgun loaded with quarters once. As she gets closer he jumps to pull the door down and as all the zombies hit the door, you can see that it's solid, no holes. But when the shot changes to the inside view, the door now has quite a few holes in it. Not only were they not there before, but the door was open, so the quarters wouldn't have hit it anyway. (01:03:50 - 01:04:20)
Continuity mistake: Alice drops her shotguns after she is knocked out by the Axeman, and a close up of the shotgun shows that it lands near one of the shower columns. And when Claire spots the shotgun, it is still lying in the spot where Alice dropped it. But in the wide shot just before Claire starts her slide, the one with both Claire and the Axeman, there aren't any more of the shower columns between them, and Claire only picks up the shotgun after the wide shot. (01:03:55)
Continuity mistake: Right after the Tower swing, Alice draws her shotguns, ready to shoot. In the close up shot of her, the shotgun in her right hand is pointing up. But in the far shot with the two zombies in front of her, it is pointing down instantly. (01:03:55)
Continuity mistake: After the Tower Swing, Alice fires a bunch of quarters through two zombies, most of which end up in the wall around Luther. But when he has closed the door, we get an overhead shot of the wall, which has a bullet hole in it - and no quarters. (01:04:15)
Continuity mistake: During the fight scene with the Axeman, Claire slides between his legs while gunning him down with Alice's shotgun. But watch his axe. In the far shot he is holding it up, like he is ready to strike, but in the shot where he is falling, the axe is leaning on the ground all of a sudden. (01:04:15)
Continuity mistake: When Alice is shining her flashlight into the tunnel, note that the shower column is on the right side of the tunnel entrance. In the shots on the outside of the tunnel, that same column is on the left side of the entrance. (01:04:30)
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. (01:04:50)
Continuity mistake: When Alice is knocked out by the Axeman, she lands on her back with a few broken tiles on her chest. When we get the far shot with the Axeman, there are suddenly a lot more tiles. (01:05:20)
Other mistake: At the end of the fight with the Axeman, Alice points a shotgun towards him, while both she and Claire are sitting on their knees (as is seen in the overhead shot with the axe in the wall). But the shotgun is clearly pointed downwards. Alice is 5'9'', while the Axeman is at least 9 ft. tall. If she wants to blow his head off, she should have been pointing it more up. (01:07:40)
Continuity mistake: In the flashback when Claire remembers what really happened on the beach where they landed the chopper, the Umbrella guard slams the spider-shaped device on her chest. In the next two shots, the device is gone, but when Alice finds her 18 months later, it's back on. (01:10:50)
Other mistake: Wesker's chamber on the Arcadia has only one entrance, a big blast door which Alice walks through. Yet Chris and Claire manage to appear behind Wesker without the blast door ever being opened. (01:18:00)
Continuity mistake: When Alice kicks Bennett away, he lands one one of the dead bodies, sliding it back significantly. But in the shot where the dog is splitting its head, you can see the head of the body in the top right corner of the screen. And it definitely is the one Bennett landed, seeing how that was the one next to the shotguns. And in later shots, you can see that all of the bodies are in their original positions. (01:18:00)
Revealing mistake: When Wesker flips Claire and Chris during their fight, in the brief sequence from the side when she lands on her back, a TCR timecode is visible in the lower-left of the screen for a single frame before it cuts to the sequence with Alice cornered by dogs. TCR timecodes are meant to be removed when a film is finished. (01:18:40)
Other mistake: Throughout Claire and Chris' gun fight with Weskers, not a single shell casing is dropping to the floor and despite every single bullet missing, no marks appear in the walls. (01:20:00)
Continuity mistake: When Bennett bends over to pick up Alice's shotgun, you can see that the floor on which it rests is covered in glass. But when K-Mart picks it up moments laters, the glass is gone. (01:20:30)
Continuity mistake: In the overhead shot with the falling glass, Alice's second shotgun is apparently lying under the table, because we can't see it. When Bennett attempts to pick it up, it has moved itself a good foot and a half away from the table. (01:24:00)
Continuity mistake: When K-Mart throws Alice's shotgun to her right before she shoots Wesker in the mouth, between the slow-motion shots, the gun switches position in mid-air before Alice catches it. K-Mart throws it with the barrel facing towards Alice but when she catches it its barrel is facing away from her. (01:24:15)
