* 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]].]] More superficially he also bares his claws in a very similar way to Wolverine.
** 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/TheMummy1999'' 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. All three of them did their own stunts for the flying scenes.
** Kate Beckinsale likewise immediately signed on after seeing the script, despite the director worrying she wouldn't want to do it after having just done ''{{Film/Underworld}}''.
* 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.
* EnforcedMethodActing:
** Silvia Collocca is terrified of heights and therefore was not acting during the scene where Verona and Aleera are hanging upside down and getting yelled at by Dracula.
** Accidental example. While shooting [[spoiler: Velkan's death scene]], the rock underneath him was covered with spiders and they bit him quite ferociously.
* FakeBrit: Australian Hugh Jackman uses a British accent for Van Helsing, as does New Zealander David Wenham for Carl.
* FakeNationality: British Kate Beckinsale and Richard Roxburgh play Romanians. The Brides' nationalities are never stated, and it's possible Aleera and Verona could be Spanish and Italian respectively like their actresses. However Marishka has an ambiguously Eastern European name and accent, and played by American Josie Maran.
* 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.
* ProductionPosse: Kevin J O'Connor, who frequently collaborates with Stephen Sommers, appears here as Igor. The role was written for him.
* RomanceOnTheSet: [[http://coolspotters.com/files/photos/835257/richard-roxburgh-and-silvia-colloca-gallery.jpg?1357420838 Silvia Colloca and Richard Roxburgh]] [[http://www.sbs.com.au/news/article/2015/01/07/i-met-dracula-and-fell-love-silvia-collocas-journey-australia fell in love and got married]] the same year the movie came out - HilariousInHindsight when you realize Dracula actually married one of his brides (Verona)! What's more is that her actress claims that Verona is the Queen Bride - so FirstGirlWins after all.
* SpiritualAdaptation: 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]].
** Michael Bay was attached to direct, but opted to make ''Film/TheIsland'' instead.
* 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.
