Il gioco (2001)

An actress and her roommate fall under the spell of an enigmatic academic in the Italian TV movie Il Gioco (Deceit) (1999). Michela (Claudia Gerini) is out at an audition when a mystery man approaches her with an envelope full of cash and a strange proposal: if she shows up at a restaurant and plays out a "scene" with the man who sits next to her, she can keep the money. Michela is creeped out by the offer but her roommate Corinna (Susan Lynch) is intrigued and takes him up on it. Turns out the man is an art historian who studies fakes. Or so he says...Well, whatever he says Mr. Skin wants to learn his secret, because he talks Claudia out of her clothes for a full-frontal reveal. That lovely liar will set your pants on fire!
