I saw this movie trailer way back in 2000.... Must be a 90's movie I guess.... I don't remember anything about it other than this particular scene.... In a fairly crowded social party, a man (probably the villain) will run through his index finger over a woman's (probably the female lead) chest, and would say
"I can rape you here.... Even Now"
.... That's the only thing I remember about that movie. From what I saw, I would say it is a stalker or a blackmailer movie. Hope this helps....
