When Blade returns to his headquarters early in the movie, Scud remarks, "The Dark Knight Returns!" This is a reference to another comic book character that hunts by night, Batman, who was the subject of a classic comic book miniseries.
In the scene when Blade cuts the vampire, Reinhardt, in half, this is a reference to the anime film Vampire Hunter D in which a similar scene occurred.
Pop Icon Michael Jackson was originally going to have a cameo in the "House of Pain" sequence as a "Vampire Pimp" that Nyssa encounters as she searches the upstairs hall. Jackson had to drop out due to scheduling conflicts and the part was played by a Czech actor. The sequence was ultimately cut out entirely for pacing reasons.
No real reapers were hurt during the making of this film.
