With Dirty Pretty Things Stephen Frears (The Grifters) gives us a dark gritty film examining London's seedier underbelly. Oscar nominated Chiwetel Ejiofor is Okwe, a Nigerian doctor who fled to Britain after the death of his family. So far he has evaded capture by the authorities and successfully held down two jobs as a taxi driver and night porter in a downmarket hotel. But all this changes when he finds a human heart blocking a toilet in one of the rooms and discovers his manager is running an organ trafficking operation offering illegal immigrants passports for organs. The plot then follows a well-trodden thriller path as Okwe wrestles with his conscience and also the growing affections of Turkish asylum seeker Senay (Audrey Tautou).

Ejiofor and Tautou give incredibly affecting performances as the disenfranchised inhabitants of the capital city and the plot is harrowing without being sensationalist. The only disappointment is the black-and-white morality that holds the film together. In a drama that sets out to challenge our perceptions and prejudices, the inappropriately Hollywood ending is a letdown that does nothing to raise this film above being a stock thriller, albeit of the more intelligent kind. --Kristen Bowditch
