Resident Evil: Extinction (2007)

Continuity mistake: After the Zombies are unleashed in the desert scene, we see Carlos crawling under the truck. At first his semi-automatic gun seems to be completely normal. The gun's slide and chamber are closed as if there are still bullets in the magazine or at least one bullet is chambered. But then the camera focuses on his gun and we see the gun's chamber is open - as if there are no bullets left. The gun didn't fire between shots so it's chamber should have been open in the first place. (00:58:10)

Alice: Good thing we like a challenge.

Trivia: The scene where a zombie appears to be "domesticated" is a clear reference to the zombie-character "Bub" from George A. Romero's film "Day of the Dead." "Resident Evil: Extinction" also includes several other more subtle references to that film as well.

Question: Is this supposed to be Albert Wesker in the film? IMDB lists him as Albert, but I'm fairly certain I saw the part listed as Sherman Wesker in the film.
