I have just found these images from Metropolitan (1990). The actress playing Audrey Rouget appears in a kind of nightmare in the male lead’s imagination in the arms of the evil Rick.
The pretty actress appears undressed but only to her slip twice in the movie, including during this sequence. So, it is a modest movie in that respect.
She was a good actress, Carolyn Farina, but sultry and sexy was not really her thing. She reminded me of Elizabeth McGovern trying to do erotic. Some actresses are too wholesome looking for that kind of scene.
