Other mistake: After Van Helsing realises Dracula's coffin is in the cellar of Michael Gough's house, he hears a scream and runs to find the housekeeper Gerda overwrought and hysterical. He needs to find out where Dracula has just gone, and so he gives her a slap. It's hilarious how loud the sound of this is.
Continuity mistake: In the final sequence where Dracula's foot has been disintegrated by the rays of the sun, his foot is seen firmly attached again seconds later as Van Helsing confronts him with a makeshift cross. In the scene Cushing, with his back to the camera, steps forward quickly from the foreground to cover the area where Lee's foot is briefly seen as having not been disintegrated.
Continuity mistake: When Harker first enters the tomb of Dracula his coffin is next to the stairs, but after Harker kills the she vampire he turns around and the coffin is against the other wall.
Revealing mistake: When Van Helsing arrives at Castle Dracula and discovers the Count's bride lying staked in her coffin, the "corpse" is visibly breathing. (00:29:10)
Factual error: When Van Helsing gives Tania his coat he tells her she looks like a teddy bear. The first teddy bear was made in 1902, 17 years after the movie takes place.
