Cult of the Damned
1969
93 Min
Tara Nicole Steele (Holly Near), the pudgy, lovelorn daughter of a hugely wealthy couple — vapid ex-porn star Astrid (Jennifer Jones) and repressed Willy (Charles Aidman) — falls under the influence of a politically subversive cult led by promiscuous rock idol Bogart Peter Stuyvesant (Jordan Christopher). Despite his engagement to Tara, Bogart seduces both her parents, forcing them all to make the ultimate sacrifice to satiate his raging ego.
Hard to say what to make of this movie... it's like "Riot On Sunset Strip" filtered through Anton Szandor LaVey's adolescent dreams.
