Factual error: Every time the silver nitrate is shown on clothing, it is shown as silver. Silver nitrate in fact is black once exposed to light.
Factual error: Selene's guns are apparently capable of firing 30 rounds without reloading. Considering the size of the ammunition, this is physically impossible.
Character mistake: On two occasions throughout the film, Kraven's accent changes - once when he is talking to Lucian near the beginning of the movie and near the end of the movie when he is telling Selene that Viktor killed her family.
Lucian: We were slaves once. The daylight guardians of the vampires. I was born into servitude. Yet I harbored them no ill will. Even took a vampire for my bride. It was forbidden, our union. Viktor feared a blending of the species. Feared it so much he killed her. His own daughter. Burnt alive for loving me. This is his war. Viktor's. And he spent the last 600 years exterminating my species.
Question: Can anyone explain Lucian's arm blade? It seems totally out of character for him, and every time he changed to wolf form he'd have to track it down and reattach it. Moreover, since these vampires don't have any weakness to metal, there's no special advantage in using a metal blade instead of his wolf claws. So what's the point?
Answer: Removal of the head kills everything. Immortal or not. At least that's what I saw.
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.
