The Vampire Lovers

1970 Hammer Horror film starring Ingrid Pitt, Peter Cushing, Douglas Wilmer, Ferdy Mayne, Madeline Smith and Kate O'Mara. It features very little horror but the storyline is quite faithful to the original story, Sheridan LeFanu's Carmilla, in the midst of (tame) nudity. Followed by two sequels, Lust for the Vampire and Twins of Evil; altogether these films are known as Karnstein trilogy.

Tropes:

 * Bling of War: In the case of the General Spielsdorf (Peter Cushing) in the ball scene.
 * Bury Your Gays: Mircalla's fate.
 * Colour-Coded for Your Convenience. In the same ball, Carmilla (Ingrid Pitt) is dressed in blood-red and her mother has black dress (although white roses in the hair). Guess what it means?
 * Fan Service: Oh, yes, very much.
 * Girl-On-Girl Is Hot
 * Haunted Castle: As per the ISO Standard for Hammer Horror.
 * Lesbian Vampire: Countess Mircalla Karnstein, also known as Carmilla and Marcilla.
 * Off with her head!
 * Ominous Fog
 * Our Vampires Are Different
 * Uberwald: Officially Styria.
 * Vampire Hunter: The Baron Hartog (Douglas Wilmer) becomes one to avenge his sister. He seeks out every member of the Karnstein family to exterminate them before they wake up from their grave and feed upon the living.
