Continuity: When Blade is leaving the shop towards the end he fills up 6 phials of EDHD, but he uses 9 phials total. 2 On the 2 people in the hall when he first gets to the building and then 7 more on Deacon at the end.

Revealing: When Blade uses his booby-trapped sword to knock down the serum from the wall at the end of the movie, you can tell the zoom in of the shot was sped up, as the rotating-timer-thing is spinning quicker than normal, and the screen is vibrating quickly.

Revealing: When Karen and Whistler start to fire at Frost's men, after they discovered Blade's hideout, Whistler shoots a black guy who has a large bump under his shirt, quite obviously the squib.

Continuity: When Blade gets back from the park after meeting with Frost and getting serum, he discovers Frost's men have been there, and sees Whistler. When Blade moves the tape, which is in a metal rotating stand, the stand rotates on its swivel, but in another shot it has only moved a little bit and hasn't rotated either. The tape would've been facing the other direction because the stand swivelled, but instead it remains in the same position.

Continuity: When Karen tells Blade to take her blood and he does, he eventually releases her and there is just some blood on his bottom jaw. In the next scene, there is blood on his teeth at the top and the bottom.

Continuity: 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.

Continuity: Close to the beginning when Dragonetti is talking to the Council he is looking at photos, then he puts them down, yet in the following shot he is holding them again.
