Marisa Mell was an Austrian actress. Typecast as a femme fatale in European arthouse and genre films, she is best regarded for her performances as Eva Kant in Mario Bava's critically re-assessed Danger: Diabolik (1968), and the dual role of Susan Dumurrier/Monica Weston in Lucio Fulci's giallo One on Top of the Other (1969).
