Continuity mistake: When the scientists are standing at the entrance to the Hive, one of them opens a small transmitter, reflected in his mask, with its antenna pointing over 45 degrees. When it cuts, the antenna is pointing almost horizontally. (00:02:45)
Visible crew/equipment: A boom mic operator wearing a white shirt is seen reflected in the door that the female scientist opens, when the Umbrella personnel pick her up, as part of their extraction procedure. He is visible as the door is opening and very faintly when it is closed. (00:04:00)
Visible crew/equipment: When the SUV is struck by the large truck and is pushed along while upside down, a camera mount can be spotted (helps if you use slow motion) and also, a tow truck can be seen actually pulling the SUV along the street. (00:05:15)
Revealing mistake: At the beginning, when one of the black trucks has an accident, whatever is making the dramatic sparks is still running when that part of bodywork is off the ground. (00:05:25)
Revealing mistake: In the early aerial shots of Raccoon City, look to the left of the screen and you can see the CN Tower, a very recognizable landmark that is definitely in Toronto, not Raccoon City. This is due to the fact that film was shot in Canada. (00:05:25)
Revealing mistake: Resident Evil Apocalypse was shot in Toronto and the filmmakers wanted to use the city surrounding the CN tower to be Raccoon City. They edited out the CN tower, however they missed a brief glimpse at it. It's shown really quickly in between when Angie's vehicle crashes and when it stops. (00:05:25)
Continuity mistake: When the girl is being chased by the zombies (just before we meet Carlos) the keypad for the door is right next to it. When she tries to enter the code, it is suddenly next to the small grey box. (00:09:30)
Suggested correction: It's next to that small gray box (appears to be a light switch) in every shot. At no point is it anywhere different.
Continuity mistake: Early on a pallet is leaning against a building with nothing next to it as two star members are backing up shooting at zombies. About eight seconds later you see an aluminum tube standing in front of that pallet. It then comes and goes. (00:15:00)
Continuity mistake: At the surplus store as a hand picks up a weapon, it is clear that the person is wearing jeans. The next shot is of a person wearing a lab coat and after that we see Alice getting dressed. (00:18:25)
Continuity mistake: In the church, Peyton asks Terri about her video camera. She has it raised to shoulder height. Cut to her face and the camera's gone. The next shot is through the camera and shows the same view of Peyton we could see before over her shoulder, so she didn't move it. (00:20:45)
Visible crew/equipment: In the scene where Nikolai is bitten and the horde bears down on the police and S.T.A.R.S., you can see some crew members and a floodlight. (00:29:35)
Continuity mistake: A zombie hits its head on a tombstone, which falls over. In the next shot, it's upright again. (00:32:40)
Suggested correction: Could easily be another zombie and another stone.
Factual error: The sniper on the roof who is casually picking off zombies hand loads his rifle after every shot. The rifle he is using is the AWP Magnum which has a spring loaded 10 round clip and a breach that cannot be hand-fed ammunition. (00:36:30)
Suggested correction: Ammo can be manually loaded, it's inefficient but not impossible.
Continuity mistake: When LJ shows his custom guns to the STARS, he opens his coat and pulls the tail behind his back. In the wide shot, his arms are out to the sides. (00:37:15)
Continuity mistake: When Nemesis blows up the STARS sniper on the roof of the theater, the size of his rocket launcher changes drastically. (00:37:55)
Character mistake: Jill states that a 5 kiloton nuclear weapon will sanitise the city, however, such a yield is far too small to destroy the city. (00:42:00)
Continuity mistake: Just before Nemesis starts shooting at Alice after shooting at Valentine, the counter on his gun shows 0000 rounds left. (00:42:10)
Continuity mistake: Nemesis has an ammunition counter for his Vulcan cannon. When Nemesis is shooting at Peyton on the bridge, his counter stops at 3997 rounds. Almost immediately he begins shooting at Jill, but now the counter reads 3688. (00:43:20)
Suggested correction: The counter doesn't "stop" at 3997, the audience's POV changes while Nemesis is still firing, and the counter is last seen at 3978. The camera switches back to Nemesis' HUD roughly 5 seconds later when it is at 3688. Considering Nemesis is firing for some of the 5 seconds between when we can see the counter, and that miniguns can fire 100 rounds per second, none of this is impossible or even implausible.
Deliberate mistake: When Alice first fights the Nemesis, she attempts to jump over a fence and make an escape. When she lands on the police car, Nemesis fires his RPG at her. If you look closely, the rocket passes magically right through a chain link fence without touching it at all. (00:44:40)
Suggested correction: Rocket made a big hole in the mesh. Clearly shown.
Continuity mistake: When Alice escapes from Nemesis falling into the garbage, she shows both hands with her fingers in good condition. Yet in the next shot, she has a very badly broken finger. (00:45:30)
