Based on Sheridan Le Fanu’s Carmilla, this eroticized vampire tale (1970) resulted from the last significant surge of creative energy at Britian’s Hammer Films, which thereafter descended into abject self-parody. Ingrid Pitt is the bisexual bloodsucker on the loose in a girls’ boarding school, and Peter Cushing is her nemesis. With Dawn Addams, Pippa Steele, and Madeleine Smith. R, 88 min.
