The Vampire Lovers (1970)

Hammer Horror starring Scream Queen Ingrid Pitt and featuring the wonderful Peter Cushing. The film attempts to disguise its lack of plot by having Ingrid’s cleavage heaving all over the frame and lusty busty lesbian embraces, but anyone over the age of twelve will see through that instantly.
Besides its enjoyably shameful tactics it’s a fun frolic through the vaults of alternative vampire lore in the usual Hammer style.
It’s the first part of the loosely connected Karnstein Trilogy; the others are Lust for a Vampire (1971) and Twins of Evil (1972).
