1. Ingmar Bergman employs images of vampirism—neck biting and blood sucking—to powerful effect in Persona (1966), his most self-reflexive film.

2. Not loosely enough: Stoker's widow successfully prosecuted Murnau, which may account for the disappearance of the original negative.

3. Herzog's simplification of the narrative frame has the same effect as would eliminating the frame story from The Cabinet of Dr. Caligari , thereby restoring the screenwriters' original subversive intent.

4. Badham's Dracula also foregrounds the sexual themes, with Lucy portrayed as an early twentieth-century feminist who openly responds to the count's seduction.

5. This scene recalls many similar hallucinatory moments in Herzog's work, most notably the response of the raftsman in Aguirre, Wrath of God first to seeing a ship atop a tree and then to being shot by unseen natives: "That is no ship. That is no forest. This is no arrow."
