Audio problem: Near the beginning of the movie, while Selene is looking at the CCTV video from outside the subway station, Kraven enters the room and talks to her. Throughout their conversation, the sound quality of his voice changes as he walks away from where the mic is located (by Selene). (00:17:35)
Audio problem: At the beginning, when Selene is hunting the Lycan though the subway tunnels, she is pressed against a wall, and she starts to look around the corner. Then suddenly a subway train passes by. Shouldn't we have been able to hear it? (00:08:10)
Chosen answer: In most of the shots, Lucien takes his coat off when he changes to wolf form, and the blade would be attatched to a mechanism in him coat. Also, the film gives us an example of the blade hurting a vampire: bloodloss. And that kind of weapon could do some serious damage, and as it probably wouldn't kill the vampires, it would almost definitely slow them down.
