Continuity mistake: After Van Helsing arrives at the castle for the first time, when Anna is rearming herself, her hands shift from on her hips to at her sides between a front shot and a rear shot. (00:37:45)
Continuity mistake: When Mr.Hyde strikes Van Helsing through the air, the hat falls off Mr. Hyde and you can see it fall behind him. When it cuts to Van Helsing flying through the air while shooting at Mr. Hyde, you can see the hat lies a few feet in front of Mr. Hyde. (00:10:10)
Continuity mistake: When Anna offers Van Helsing a drink and says the bar is down the hall, she grabs a spiked club and starts walking while placing the club to her belt. When it cuts she places it again. (00:38:30)
Continuity mistake: When Anna and Van Helsing is looking down the well for the bride who is hiding there, notice the width of the well. When we are looking up at Anna and Van Helsing from within the well we can see that the width of the well has increased a few feet. Also Anna's position when looking down the well changes during the shots. (00:27:30)
Other mistake: During Dracula's ball, when Anna looks into the mirror after Dracula lowers her, the reflection shows an entirely empty room. Even though the vampires don't cast any reflections, the furniture should still be seen in the mirror.
Continuity mistake: In the scene where Van Helsing is fighting Dracula's brides for the first time, when the sun comes up and they disappear, there is a wooden table behind Anna when she stands up, and there's nothing on it. But a couple of shots later there is the dead body of a man on it.
Other mistake: When there is a werewolf transformation, the infected person's skin falls off to reveal the werewolf underneath. When changing back to human, the werewolf's skin falls off. When Van Helsing becomes a werewolf, his human skin falls off as he changes. As he battles Dracula as a werewolf, he grabs Dracula's throat. As soon as he does, the full moon is covered by the clouds and Van Helsing simply reverts to his human form. No werewolf skin falls off, he just changes back.
Continuity mistake: As the cage is being dragged up along the trees, right before Velkan jumps off, you can see ropes and equipment attached to the tree on the right. It cuts to Velkan jumping off the cage and the cage continues being dragged up along the tree. When the cage stops you can see the same ropes and equipment to the right as previously seen. (00:21:05)
Revealing mistake: When Dr. Frankenstein is holding the sword against Dracula, you can see its shadow on the wall to his left. However, when Dracula impales himself with the sword you can see the sword's shadow going through Dracula's shadow at the same time. Whatever the film makers have done, they have forgotten to remove the sword's shadow. (00:03:30)
Deliberate mistake: In the first sequence, you see a man riding on the wooden battering-ram, and you can see where two different shots of the same man were spliced together, as the background suddenly shifts from being a forest, to being the exterior of the town, where the stone wall is. It was meant to be one single shot, but you can just see how the trick works. (00:00:30)
Continuity mistake: Right after Anna's brother and the werewolf dive off the cliff you can see Anna getting up a few feet from the edge of the cliff. When it cuts she lies right next to the edge. (00:21:50)
Continuity mistake: When the Bride is down the well in the village, the sun is out. When it goes back behind a cloud, the shadow can be seen crossing the ground. When Carl points this out, the shadow is back where it was a few moments before. (00:27:40)
Continuity mistake: After the vampire has thrown the bull through the building wall we see Van Helsing turning his head around noticing Anna running. If you look behind Anna you can see something orange resembling what could be haystack of some sort. When it cuts to a closer look of Anna running you can still see it behind her. When it cuts back to Van Helsing still looking her direction it is gone. (00:26:10)
Revealing mistake: When Verona grabs Van Helsing of off the chariot/coach, you can see the special effect of her claw holding Van Helsing is not quite matched up. The claw "wobbles" slightly over Van Helsing's arm. And this does NOT have to do with the fact he is struggling. (01:12:50)
Revealing mistake: In the beginning when the Frankenstein Monster throws the equipment on Dracula you can see the outline where the wire used to drag Dracula backwards is attached. (00:04:10)
Continuity mistake: As the cage with the werewolf in it is being dragged up you see Velkan landing on it on his side. However when it cuts to his loosing his gun he lands on his stomach. (00:21:00)
Continuity mistake: When the Frankenstein Monster manages to get himself loose from the table you can see him ripping off the strap by its attachment on the table. Later when Dracula gets to the table you can see the strap leather has been ripped in two on the middle instead. (00:03:50)
Factual error: The Hungarian Parliament appears both in the film's Budapest and on the official posters. The film is set in the 1880's. The Parliament was built in the 1900's. (01:18:30)
Continuity mistake: When The Velkan saves Anna from the wolf and is subsequently thrown off the cliff by the beast the splash sound as they hit water is heard a split second later. However as the camera pans back we see the cliff is meant to be several hundred feet high. It would be impossible for them to reach the water in that time and the splash sound at that distance would be imperceptible. (00:21:50)
Continuity mistake: When Van Helsing is talking with the undertaker and the undertaker says "Never to late digging graves", he lifts his shovel. When it cuts from behind him the shovel is lowered. (00:44:45)
Answer: After being killed - "murdered" as Dracula stated several times - by Van Helsing, Dracula made a deal with the Devil to regain his life. Carl tells his story when telling Van Helsing and Anna everything that he has learnt.
