 Although the term "Blood Countess" is used in the movies synopsis,  it is never said within the movie. When Hutch and Abigail are are  hearing the story of Elizabeth Bathory from the author of the book  "The Lady of Blood," the author says, "Thus began her obsession,"  (speaking of using the blood of the girls as a "Fountain of Youth,"  as Abigail says.) to which Hutch replies, "The Blood Countess." (Not  in the theatrical version, but at approximately 1 hour 1 minute and  44 seconds on the uncut DVD)
