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. (Time)

Revealing: If you slo-mo the scene where the semi collides with the SUV carrying the doctor's young daughter, you can see the the right front of the SUV is substantially off the ground even before the truck strikes it, presumably to ensure it flips. (Time)

Other: 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. (Time)

Continuity: In the scene 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. (Time)

Continuity: Watch the scene where Alice almost pokes the scientist with the pen. In the close up shot of the guy's face, she almost poked him in his left eye. In the far shot, the pen is being pointed at his right eye. (Time)
