Corrected entry: in the room which contains manuscripts from the book of Erebus, Blade senses the child vampire but when he actually comes face to face with her, he offers her his hand as if she is human. This is only a mistake because she moved like a vampire and he showed earlier on the film that he was very capable of sensing whether people were vampires or human. Yet he didn't notice that she was.
Corrected entry: When Blade is rescuing Karen from the hospital, the police mistakenly believe he is kidnapping her and proceed to open fire on him while he is carrying her, and then again when he jumps to the rooftop across the street. Police officers would not fire freely at a suspect when his supposed hostage is in such close proximity due to the obvious risk of accidentally shooting the hostage.
Corrected entry: Silver has a melting point of 962° celsius - some alloys melt a little lower, but in any case these kind of temperatures are not obtained using a small open top thin walled bench-top melting pot. Blade uses regular equipment for normal lead projectiles (melting point of 327.5° celsius), which would not work with silver.
Corrected entry: When Blade and Karen are in the room of manuscripts, Quinn comes in with a load of guys. When one of the guys loses a hand by holding Blade's sword, there's blood all over the handle of the sword, yet, the next time we see the sword, there's no blood at all. (00:50:45 - 00:52:30)
Corrected entry: Karen knows the reaction between the vampire blood and EDTA is going to be energetic, in fact so much that she feels the need to advise Blade to take a step back. As such, why on earth does she demonstrate it under a microscope, gratuitously blowing up expensive equipment? Hardly a prudent move for an underground resistance movement.
Corrected entry: In the scene where Frost is talking to the senior, pure blood vampires he says that they shouldn't make deals with humans: "For God's sake, these people are our food." However, when he's telling Karen about the "Blood God" he says that everyone in its path will be instantly turned. If that happens, where would the vampires get their food?
Corrected entry: At the beginning of the movie, Dr. Curtis Webb does not have a British accent. Later towards the end of the movie, when Karen is thrown into the pit with him, he is a zombie vampire with British accent. (01:33:35)
Corrected entry: Frost is running his computer translation of the vampire bible because "it is a dead language" - yet when Blade shows the scrap of vampiric bible to Whistler, he is able to read it no problem - it doesn't make sense that Whistler can read it when the pure-blood council members cannot.
