Mistress Kane

Mistress Kane is a supporting character in the Scary Movie franchise. She was played by actress Jennifer Curran.

History
Mistress Kane was a woman named Victoria who had a clandestine love affair with businessman Hugh Kane. Kane's wife, Caroline, records in her diary that she suspected her husband was having an affair with the babysitter (despite the fact that they had no children). One day, Caroline came home and found Hugh and Victoria together in the kitchen and reportedly killed them. Victoria's ghost became trapped in Kane Manor with Kane.

Years after her death by Hanson, the caretaker, Caroline possessed student Cindy Campbell and tried to seduce Professor Oldman in order to reveal her husband's affair. Appearing as a Succubus, Victoria soon appeared physically to Oldman later and enticed him into following her, but when she revealed her demonic form to him, he rejected her, and she killed him as a result. Later, she appeared to Shorty, who had sex with her with a paper bag over her head. She stayed in a relationship with him after; she was last seen giving oral sex to Shorty while he ran over Hanson in his car.
