Continuity mistake: When Lestat slices the whore's wrist at the hotel, blood drips everywhere on the couch, but when she stands up in the next shot, there is no blood anywhere. (01:56:12)
Visible crew/equipment: At the end of the movie, at the bridge inside the car there is a fight between Lestat and Daniel so no one should be driving the car, but you can clearly see a man driving it and he's all covered in black. (01:56:10)
Revealing mistake: In the scene in the hotel with the two serving wenches, Lestat bites the woman through her dress and she gasps showing a complete line of fillings. (00:32:30)
Revealing mistake: After Lestat bites the breast of the whore and she begins to scream, he bites her wrist and you can see the outline of the blood device in the sleeve of her dress.
Continuity mistake: In the scene where Louis is convulsing in the graveyard after taking blood from Lestat, in the background you can see Lestat trying to sit up in front of the tomb and makes it half way up, in the next shot he is getting up from being on the ground all over again. (00:13:30)
Factual error: Paris was surrounded by the German army on September 20th 1870, until January 1871 due to the aftermath of the Franco-Prussian War. This was an obvious danger after the defeat of the French army on September 2nd. No-one in Paris, however, seems to notice. (01:10:25)
Continuity mistake: When Lestat and Louis are in the graveyard and Lestat is turning Louis into a vampire, when he first drops his blood into Louis's mouth there is blood dripping all down one side of Louis's face. He sucks Lestat's blood and it's still there, then when he starts convulsing because his body is dying, he has blood only on his chin. (00:13:00)
