Half Moon Street (1986)

A smart, PhD from Harvard, woman (Sigourney Weaver) is doing research at a British institute involved in Middle East affairs. Since her salary is minuscule, she moonlights with an escort service which pays handsomely. When she becomes romantically involved with one of her clients (Michael Caine), a politician in the House Of Lords, she finds herself unwittingly involved in international intrigues. Based on the novel DR. SLAUGHTER by Paul Theroux (who also wrote THE MOSQUITO COAST), this erotic political thriller stretches believability but is fortunate enough to have two lead actors who make it believable. The idea of an intellectual call girl is a bit far fetched but when she's played by Sigourney Weaver (one of the few actresses who can make intelligence sexy), you buy it. It's a minor film in both their careers but eminently watchable. Directed, perhaps over directed, by Bob Swaim. I'm not a fan of synthesizer scores but this one by Richard Harvey is quite good. With Nadim Sawalha, Maria Aitken and Patrick Kavanagh.
