The Addiction (1995)

Kathleen Conklin, an introverted graduate student of philosophy at New York University, is attacked one night by a woman who calls herself “Casanova.” She pushes Kathleen into a stairwell, bites her neck, and drinks her blood. Kathleen soon develops several traditional symptoms of vampirism, including aversion to daylight and distaste for food. She grows aggressive in demeanor, and propositions her dissertation advisor for sex at her apartment, afterward stealing money from his wallet while he sleeps. Jean, a doctoral candidate in Kathleen’s cohort, notices a rapid change in Kathleen’s personality.

During finals week in the library, Kathleen meets a female anthropology student. The two go to the woman’s apartment to study, where Kathleen bites her neck. While the young woman weeps incredulously, Kathleen coldly informs her: “My indifference is not the concern here, it’s your astonishment that needs studying”.
