From 1983? Yes. IMDb [a good source of info on films and actors/directors] describes it this way: Miriam, a centuries-old vampire, preys on urban clubgoers with her vampire lover John. When John suddenly ages and wastes away, Miriam casts her spell upon Sarah, a doctor who researches premature aging. This neo-Gothic exercise in style and atmosphere is perhaps most widely known for a lesbian sex scene involving Miriam and Sarah, played by Catherine Deneuve and Susan Sarandon.
I've seen it, a while back. Quite good, suspenseful, and as I recall David Bowie is in it as a vampire.
