Courtesy of IMDB: . . Dr. Lauren Slaughter, a research fellow at the Arab-Anglo Institute in London is utterly frustrated by her job. To supplement her income, she starts moonlighting at the Jasmine Escort Service, where she has more control over men and money than she does at the office. On one of her 'dates', Lauren meets the politician Lord Bulbeck who is trying to mediate a peace accord between the Arabs and Israelis. Bulbeck falls in love with his escort, and unwittingly, Lauren becomes a pawn in some very dirty politics.
This is Sigourney in a funny bath moment from the movie "Half-Moon Street"
