* ActorAllusion:
** Kate Beckinsale's character hunts [[Film/{{Underworld}} vampires]]. This was originally what was preventing her from being cast; as she had just done ''Underworld'', Steven Sommers feared she wouldn't want to do another vampire film. However her agent convinced him to send her the script - and she immediately signed on.
** Hugh Jackman [[Film/X2XMenUnited plays the role]] of a grim loner with no memory of who he was, while facing an enemy who knows him and his forgotten past and taunts him for it. He also [[spoiler:turns into a [[{{Wolverine}} werewolf]].]]
** Silvia Collocca (Verona) has often been compared to fellow Italian actress Monica Bellucci. It can't be a coincidence that Collocca is playing the same character Bellucci played in ''Film/BramStokersDracula''.
** A Director Allusion for Stephen Sommers. Van Helsing was supposed to be fully nude after [[spoiler: Anna's death]] and they filmed it as such. However a CGI loincloth was digitally added in post production. Sommers had previously done something similar in ''Film/TheMummy'' where he used CGI to cover up Rachel Weisz's nudity during her WetSariScene.
* AwesomeDearBoy: Josie Maran (Marishka) said as much about playing a vampire who can fly. It seems to be the case with the other actresses playing the Brides too.
* BetterOnDVD: The film earned over $65 million in its first week of DVD sales - which is more than half of the theatre revenues.
* CreatorBacklash: A minor example. Kate Beckinsale hated the corset she had to wear as Anna, saying she wanted to burn it all by the time filming was over.
* DeletedScene: Aleera originally featured in the masquerade ball. Elena Anaya spent quite some time rehearsing the complicated dance routines - only for all her scenes to be cut. A photo exists of her in a sparkly red gown licking Anna's neck.
* HeyItsThatGuy:
** [[Series/NewTricks Brian "Memory" Lane]] is the cardinal who gives Van Helsing his missions.
** [[Film/{{Underworld}} Selene]] has become a vampire hunter.
** [[Film/TheLordOfTheRings Faramir]] is Friar Carl
** [[Film/MissionImpossibleII Hugh Stamp]] is Dracula!
** Even as Igor, [[Film/TheMummy1999 Beni]] still finds it hard to believe that [[LaserGuidedKarma he'll get his]].
** Aleera might be recognisable as the girl from Justin Timberlake's video for "Sexy Back".
* HilariousOuttakes: Ones that {{lampshade| hanging}} almost every single facet of the film.
* IronyAsSheIsCast: Silvia Collocca (Verona) is terrified of heights. And yet she plays a vampire who spends more time in the air than she does on the ground.
* SpiritualLicensee: This movie is very, ''very'' ''Franchise/{{Castlevania}}''. Namely when Dracula turns into a bat-demon (cue "Dance of Illusion").
* StillbornFranchise: There were plans for a sequel and a spinoff TV series, ''Transylvania'', but they were scrapped in light of the lower-than-expected box office and mostly bad reviews.
* TropeNamer: DoUntoOthersBeforeTheyDoUntoUs was named after Igor's line.
* WhatCouldHaveBeen:
** The Film/CreatureFromTheBlackLagoon was originally going to be the one guarding [[spoiler: the werewolf cure]] in Dracula's castle.
** Also, the storyboard from that seen refer to Anna as "Mina", implying she was originally meant to be [[Literature/{{Dracula}} Mina Harker]].
* WritingAroundTrademarks: Inverted. The producers specifically changed Van Helsing's first name from Abraham to Gabriel so they could hold onto certain rights for the character. Also because Stephen Sommers didn't think he could have a lead with Abraham as a first name.
