Continuity: During the horse carriage chase sequence, Van Helsing is tearing through a narrow canyon with steep rock faces on both sides towering above the roof of the carriage.

Revealing mistakes: The stake that Van Helsing uses on Dracula wiggles when Dracula jerks it out of his chest.
Revealing mistakes: The glass of blood one of the Brides drinks leaves a pulpy residue on the glass–a trait of tomato juice.
Revealing mistakes: At the masquerade ball, after Carl knocks the firebreather into Dracula, we see Dracula reach for the performer, and you can hear him scream. As Van Helsing swings by to grab Anna, Dracula’s arm is in the air, as if he’s thrown the man, but he is not visible.

Factual errors: At one point, Carl and Van Helsing cremate the body of a human ally. However, the Catholic church – which Carl and Van Helsing serve directly – did not lift its prohibition against cremation until 1963.
