Other mistake: When Krolock ambushes Sarah in her bathtub, he bites her well above the place where the bite marks later show.
The Fearless Vampire Killers (1967)
1 other mistake
Directed by: Roman Polanski
Starring: Roman Polanski, Alfie Bass, Jack MacGowran, Jessie Robins
Revealing mistake: It is obvious that the night scenes were filmed in broad daylight, since clear shadows are still cast on any available surface.
Count Von Krolock: A year ago exactly on this same night we were assembled here in this very room: I your pastor, and you my beloved flock. With hopefulness in my heart I told you then that with Lucifer's aid we might look forward to a more succulent occasion. Cast back your minds. There we were, gathered together, gloomy and despondent, around a single meager woodcutter.
Trivia: It was during the casting tryouts for the movie that Polanski and Tate first met; they got married about two years later.
