Trilogy of Terror is a 1975 American made-for-television anthology horror film directed by Dan Curtis and starring Karen Black. It features three segments, each based on unrelated short stories by Richard Matheson. The first follows a college professor who seeks excitement with her students; the second is about twin sisters who have a bizarre relationship. These two segments were adapted by William F. Nolan. The third, adapted by Matheson himself, focuses on a woman terrorized by a Zuni fetish doll in her apartment. Black stars in all three segments, and plays dual roles in the second.
