Comments (Vampire)

In a reply letter of 27 Oct 1961 to Jean Sémolué’s question, "Comment faut-il expliquer l’orthographe de Vampyr (et non Vampire)?,” Dreyer made the following statement about the film’s title,
"VAMPYR instead of VAMPIRE is a mistake by the distributors, since VAMPIRE both in France and in England is the correct word. In German the word is spelled VAMPIR, so I do not understand at all from where the word VAMPYR originates."
