Paul arrives in the village well after nine o'clock in the evening. He is thrown out by the landlord, and goes to Dracula's castle. He arrives there the same evening, so Dracula's castle shouldn't really be that far away from the village. When Simon and Sarah leave Dracula's castle in the morning, they don't arrive in the village before it's evening again, although they made the whole trip in Dracula's coach.
Maria, the landlord's wife, is supposed to be killed by Dracula's bats. When the landlord approaches her and touches her shoulder, her head moves to the left. At the same time however, the actress portraying Maria also moves her left eye from the right to the left, which should not be possible if Maria is really dead.
The goof items below may give away important plot points.
Simon finds Paul hanging from a wall with a hook stabbed through his back and out to his chest. In the close up, Paul's mouth is open with his top front teeth showing. In the next shot, his mouth is almost closed with no teeth showing at all.
