Other mistake: Blade talks to Karen about killing vampires using a stake, silver, sunlight or garlic and says that you aim for the head or the heart, but when he fights his mother in the temple he stabs her in the stomach with a bone and she turns to ash.
Other mistake: Smoke rises from Karen's collar while she's lying on the table before she's injected with allium sativum. It's the shot that ends with Whistler reading her ID badge.
Other mistake: Right before Blade confronts Frost at the end, he is shown beating up several henchmen vampires using punches and kicks, before grabbing his sword. As he grabs his sword, you see several of the henchmen vampires "burning up" in the background. However, it was earlier established that to "burn up", vampires had to be killed by traditional means. (Staked with silver, exposed to sunlight, etc.) So it makes no sense for these henchmen to burn up from only being punched/kicked. It can't be due to his sword, as he twirls it in front of them, and only after they are already burning up.
Chosen answer: I have taken the Russian subtitles and machine translated them, then edited for clarity. Here they are with and compared to the hard subs from the theatrical release of the movie. Russian version is in brackets. Here is the full conversation... MOSCOW Woman: (A good show. I'm glad we went.) Vampire: (It went well, I thought?) Woman: (Yes, keep up the good work.) Vampire: (I will try.) Woman: It's cold. Where are we going? (I'm so cold. Where are we going?) Vampire: It's a surprise. Woman: Surprise? (Surprise? Really?) Man: (Yes.) Woman: I like surprises. (You know, I like surprises.) Vampire: Then you'll like this - (Then you'll like it very much.) Vampire: (You have such sweet skin!) Woman: (Peter, what are you doing? You're hurting me!) Vampire: (You will live forever.) Woman: (Don't touch me!) Blade: (Hey, good evening.) Blade: Catch you at a bad time - Blade: - Comrade? Vampire then growls until blade draws his sword and it cuts to credits.
