Don't forget King's time with Blade, Jarko, and Jarko's vampire dog.
Blade: How do you finance this operation? King: I date a lot of older men.
King: (sees Jarko's dog, which is a vampire Pomeranian) Oh, fuck me. (two big scary dogs join it) Oh, fuck me sideways. Nice doggies. (the dogs reveal reaper mouths and chase him)
Jarko: Hey dickface, have you seen my dog? King: (who just made the dog and the two others fall out a window after they tried to eat him) Have you tried the lobby?
King: So Blade, if this works, and all the vampires go bye-bye, what's left for you? I don't really see you teaching karate at the local gym. (Blade looks annoyed and walks away) He hates me, doesn't he?
This one scene where Blade, Hannibal, and Abigail are dangling a familiar off of a multi-story car park when someone's cellphone goes off. Blade looks around to his teammates, then down at the guy he's dangling.
Blade: Oh, it's you!
And then Blade takes the call for him, in the process of getting the info he was after, and passes the phone back.
Blade: It's for you.
Familiar: Hello? (screams as Blade promptly drops him to his death)
When being interrogated:
Dr. Edgar Vance: How about the president? You know who that is. Who's in the White House right now?
Blade: An asshole.
(This handily avoids dating the movie, since regardless of who's in office, someone will believe them to be an asshole).
Blade coochie-cooing at a baby… and the baby immediately crying.

For the sequence when Abby shoots Drake with her bow, Jessica Biel was coached to aim directly into the camera's lens, which was protected with plexiglass except for a tiny opening right in front of the lens. But her aim was so true that her arrow went straight through that tiny opening and destroyed the camera (valued at around $300,000) - in the outtakes, she sees what she has done, and bursts out laughing.
