The premiss may be a bit far-fetched but this screen version of Paul Theroux's novel "Doctor Slaughter" is surprisingly robust and very enjoyable. Sigourney Weaver is the underpaid American working for the Middle East Institute in London who decides to supplement her income by working for an escort agency. However, things get murky when one of her clients turns out to be Michael Caine's diplomat charged with brokering an Israeli/Arab peace deal. Has Sigourney been set up and if so, by whom? It's hardly believable, of course, but the director, Bob Swaim, ensures it moves at a fair clip though he does play down the thriller aspect to beef up the love story that develops between Caine and Weaver. He also keeps you guessing as to who is doing what to whom. It wasn't a success but it's also a lot better than its critical reputation might suggest.

Dr Lauren Slaughter is an American academic who comes to London to work for a foreign-affairs think-tank. Her work is prestigious but badly paid, and Lauren decides to supplement her income by moonlighting for an upmarket escort agency, mostly catering for the needs of wealthy foreign businessmen. The set-up is not officially a prostitution ring, but sails fairly close to being one; the idea is that the man pays for the girl's company and it is then up to her whether she goes to bed with him. Lauren proves a success in her new line of work and is able to leave her downmarket flat for a much more exclusive residence in the Half Moon Street of the title. The film explores what happens when she falls in love with one of her clients, Lord Bulbeck, a Government foreign office minister involved in negotiations towards a Middle East peace settlement.This is not really one of Michael Caine's best films. Most of his best performances have come in films where he has played characters who are, in one sense or another, outsiders or rebels against the system- the down-at-heel spy in "The Ipcress File", the Cockney womaniser in "Alfie", the gangster in "Get Carter", the cynical, disillusioned academic in "Educating Rita" or the drunken minor diplomat in "The Honorary Consul". Admittedly, his first starring role was in "Zulu", where he played the upper-class Lieutenant Bromhead, but I have never thought he was the best thing about that film. Here he plays a high-ranking establishment figure, but never seems completely convincing in the role, even though Bulbeck, a working-class trade union official raised to the peerage, is a co-opted member of the British establishment rather than one born to the purple.Sigourney Weaver, however, is better as the heroine. She was, along with the likes of Meryl Streep, Kim Basinger, Jessica Lange and Michelle Pfeiffer, one of the bright new generation of Hollywood actresses who came to prominence in the late seventies and eighties, and gave some great performances in films like "Alien", "Gorillas in the Mist" and "Working Girl". Here she captures the various, often conflicting, aspects of Lauren's personality,- her intelligence, her outgoing nature and a hint of an underlying mercenary ruthlessness, which nevertheless co-exists with a genuine capacity for love.For most of its length the film is a psychological romantic drama, like a romantic comedy without the jokes, and as such it works reasonably well. Towards the end, however, it morphs into a political thriller as Lauren discovers that she has become embroiled in a conspiracy by opponents of the Middle East peace process to assassinate Bulbeck, and as a thriller it does not work well at all, failing to generate any real tension. Despite a promising beginning, this sudden switch from one genre to another means that "Half Moon Street" is one of those films that fall between two stools. 6/10

Half Moon Street is basically an average film with some good talent in it. From the reviews this is a movie people either love or hate, but I think the elements balance each other out and the end result lands it in the middle of the film quality spectrum. Sigourney Weaver comes across totally convincingly as a Mid East scholar who becomes an escort by night to make ends meet (anyone who is a fan of hers will probably appreciate her many nude scenes!). Michael Caine also gives a good performance as an English lord trying to broker a secret Middle East peace deal. Where this film falters is in the script, which is too talky and it seems to take a long time for the story to get going. The last twenty minutes is well filmed and exciting, but there is a lot of plodding to go through before the good part arrives. Fans of Caine and/or Weaver will probably love it; for everyone else, not really a bad film, but not really great either.

I admit that I only rented this film because it has my favorite actress, Sigourney Weaver, but I was surprised to find out that this is a well acted, well written, and extremely entertaining gem. I expected the film to be pretty mediocre and kinda dull since it involves politics, but Half Moon Street is now one of my favorite films. Plot: (POSSIBLE SPOILER OR 2)Dr. Lauren Slaughter has grown tired of her low paying posistion at a university in London. She recieves a videotape from an anonymous person and watches it immediately. It turns out to be about an Escort Service. At first she thinks it's completely rediculous, but then realizes she doesn't have very many options, so she goes for an interview and gets the job. She is brought into the life of Lord Bulbeck, a British diplomat who is working on a top secret peace settlement with the Middle-East, and the two come to like eachother. What they both don't know is that someone is watching them and that now they're lives are in jeopardy. The Good:An original plot that is pulled off quite well. Great performances from everyone, especially Weaver and Caine who have a great chemistry together. The pace is fast and there's lots of suspense and intrigue. I also love the music score.The Bad:The pace lags at times, but other than that I saw few problems with this movie.Overall rating: ***** out of *****
