Continuity mistake: When Alice knocks over the giant Licker in the Rolls-Royce, the driver's side of the car remains completely undamaged. Unlikely, but for the rest of the chase there are four giant scratches across the rear of the car. (00:51:10 - 00:52:05)
Continuity mistake: Outside of the corridor of light sequence, nobody ever seems to run out of ammo, or bother to reload, most notably Ada and Alice.
Continuity mistake: When Jill Valentine jumps out of the Umbrella chopper, her outfit and guns differ from what she was wearing and carrying in the post-credits scene of Resident Evil: Afterlife. (00:05:55)
Continuity mistake: In the scene when Ada Wong walks into the Umbrella control room and kills all the agents, she stands in the middle of the room. She uses a gun to kill all the agents, who are sitting behind glass computers. In that scene, and in later shots, we can see that the glass is intact and has no bullet holes in it.
Continuity mistake: The Rolls-Royce constantly goes from being bulletproof, to not being armored at all.
Continuity mistake: Ada Wong seems to never run out of ammo. She never reloads and she doesn't carry any magazines with her. Alice's Kriss Vectors should only hold 13-33 rounds but she fires more than the rounds. She doesn't hold any mags.
Continuity mistake: During the fight in the corridor of light, Alice shots everybody and there are a lot of blood splattering, but the corridor continues to be clean until the very end, and the stains of blood that are there are not compatible with the splatters. (00:21:50)
Continuity mistake: When housewife Alice is trying to escape with her daughter in the laundry room, she slams a mop through the ceiling. When she slams the mophead through the ceiling the last time and pulls it out, the hole left behind is maybe one foot across. When she lifts her daughter up into the hole it is now a good two or three feet across and reaches from ceiling support beam to support beam. (00:09:20)
Continuity mistake: One of the zombies fires an RPG into a yellow van. The van then moves forward and bumps into another car in front of it. When Alice jumps through the van, they have moved apart again. (00:50:45)
Continuity mistake: When Alice is being chased in the corridor of the Tokyo simulation, the woman in the blue dress is a good distance away from her. However in the following shots she is much closer. (00:21:15)
Continuity mistake: When the Tokyo sequence is started, Gill's hair is untucked from her ear. When the rain starts however her hair is tucked behind her ear. (00:19:00)
Continuity mistake: Alice ejects the magazine during the corridor sequence and it drops pretty much straight down to the floor. When the camera changes to her kicking the magazine away, its falling down and out. (00:22:15)
Continuity mistake: When housewife Alice is hiding in the closet, the Majini has his tentacles in the slats of the door. When Alice bursts out he is much further away. (00:14:00)
Continuity mistake: When the car comes to a stop after killing the licker, the front wheels are straight and flush with the body of the car. When the camera changes the wheels are turned over to the left and sticking out. (00:52:20)
Continuity mistake: In Resident Evil, Alice's scar is on her left shoulder. In this film it's on her right. (00:15:50)
Continuity mistake: In the opening sequence, while Valentine and her goons shoot the people on the boat, only the exit hole of the bullets is visible, but no entry hole on the white shirts. (00:03:00)
Continuity mistake: When the Rolls Royce jumps through the yellow van, the Spirit of Ecstacy (the emblem of Rolls Royce) breaks off, but at the end of the chase, it's still in place. (00:52:55 - 00:55:50)
Continuity mistake: In the 3D map scene both of the teams are heading to the central suburbia section to rendezvous; however when it shows their movements on the map both teams are walking away from this area, back the way they just came from. (00:37:15)
Continuity mistake: At one point during the chase, a zombie pulls up and shoots the driver side window, during an inside shot. The shot then briefly cuts back outside, and look closely: the driver side window is still there.
Continuity mistake: In the corridor fight scene, the camera shows Alice shoot a zombie in the head, and very shows a bullet entry and exit point. In the next show however, the wound has disappeared. (00:23:15)
Chosen answer: They might bring them up in the next movie. Jill Vallentine was also lost for so many movies.
