Trivia: As well as the Scud and del Toro Hellboy connections, Ron Perlman, who plays Reinhardt, plays Hellboy, and Mike Mignola, creator of Hellboy, helped create the look of Blade II as a concept artist. Del Toro and Mignola got together during the making of Blade II to talk about making Hellboy into a movie.
Trivia: At the end of the film, Rush is killed by Blade, who is hiding behind the curtain at a peep-show booth. In the 1996 film "The Crow: City of Angels", the lead character Ashe surprises a villain in the same manner. Both films were written by David S. Goyer. Goyer had disowned "The Crow: City of Angels" however, due to studio-enforced edits, and decided to re-use the scene in this film.
Trivia: During the ending of the film, when we see Rush in the sex shop, pay close attention to the... *ahem*... dildos on the counter in front of him. Eagle-eyed viewers will notice that one of the dildos is actually the elongated tongue of one of the "Reaper" vampires seen throughout the film. It was left a generic "fleshy" color to help it blend in with the dildos on the counter, but it's there.
