Continuity mistake: Wesker arrives at the command post to get a report. Note where he is stood however as his position in relation to the black lines on the floor is constantly changing. (00:06:20)
Continuity mistake: Before the opening fight scene, we can see the guards running towards the entrance past a row of Hummer H2's. But after Alice blows the second group away and takes out those cars, they all of a sudden change to H1's. Also it can't be one from the opposite end, because those have a pick-up truck rear end, and the one lying on its side has a slanted back end. (00:07:15)
Continuity mistake: Right before the Needle Dive, the two Alice clones can be seen wearing high heels when they are standing still shooting the Umbrella soldiers and flats when they run towards the window and jump through it. (00:07:45)
Continuity mistake: During the first fight, the boots of Alice change from high heels to no heels and back to high heels several times. (00:08:10)
Continuity mistake: Wesker shoots the supervisor in the head for questioning an order, The guard falls to floor and his position changes several times depending on the shot. Note his head and pool of blood in relation to the lines on the floor. (00:10:30)
Continuity mistake: The bullet holes in the doors the two Alice clones dive through near the start are constantly changing place. (00:11:05)
Continuity mistake: During the initial fight scene, one of the Alice clones takes cover behind a pillar, which is fully intact. When the shot cuts to show her and the other clone, there are three bullet holes that have mysteriously appeared in the pillar. (00:11:10)
Continuity mistake: During the initial fight scene, the clone who survives the Needle Dive is later on shot by Wesker, upon which she drops two grenades. Where did she pull those grenades from? Right before she jumps out of the window, you can see that there are no grenades dangling from a belt, and there isn't much room to hide something like that in a skintight catsuit. (00:12:00)
Continuity mistake: After the Needle dive, Alice lands on a table. When she is shot by Wesker, the table is covered in blood. In the overhead shot afterwards, the amount of blood changes drastically. (00:12:05)
Continuity mistake: Alice ties Claire up to a double engined plane. In the satellite shot, it changes to a single engined plane. (00:25:00)
Continuity mistake: When Luther ducks to avoid getting hit by Alice's plane, his gun falls out of his pants. He then picks it up again just before he runs off to clear the roof. But in the shot where Angel runs away, his gun is still lying in the middle of the "E." (00:30:20)
Continuity mistake: Alice does her pass of the prison and Kim-Yong can be seen hitting the deck away from the white lines of the help us sign. However in the wide shot he is on a white line. (00:30:50)
Continuity mistake: When Alice makes the first approach to land on the roof of the prison, Luther shouts "Down!", and they all duck. In the close up shot of the group, you can see that Angel and Bennett are facing the same way as Luther and Kim. But in the wide shot, they are facing in the opposite direction. (00:31:30)
Continuity mistake: Right after Alice lands on top of the prison, she makes three skid-marks on the roof: one with each wheel. These are seen best in the shots which show the front of the plane. But in the overhead shots, the skid-marks are gone. This can be best seen in the shot where Luther grabs hold of the tail wing. (00:32:50)
Continuity mistake: When inspecting the plane for damage, the propeller changes position without being touched. The side by Alice goes from the 8 o'clock position to the 10 o'clock position. (00:34:30)
Continuity mistake: In the shower scene the shower is turned off but you can still hear it running. Then it switches back on. You can see it off and on during same scene but the sound is always running. (00:50:00)
Continuity mistake: Luther shoots the Axeman in the head, just above where his left eye should be. When the Axeman reaches the shower, the hole in the burlap sack and the blood are gone. (00:54:40 - 01:05:00)
Continuity mistake: When Crystal is emerging from the water, she is almost out of the water completely in the long shot. As the camera changes to a close up, she's much further back into the water. (00:54:40)
Continuity mistake: When Bennett shoots Angel, the blood covers Kim's right shoulder. We then get a shot of Bennett, and when the camera cuts back to Kim, some of the blood has already dried up, in less then a second. (00:56:40)
Continuity mistake: During the scene where Bennett takes off in the plane, the concrete edge suddenly disappears. He hadn't already taken off, because he makes a huge dive directly after leaving the roof, and even if he did use it as a ramp, then it makes no sense why Alice did smash through the edge. (00:58:00)
