This is a well-written, well-directed dark thriller. Steven Knight's story of illegal immigrants in London faced with imminent peril is striking. These characters uphold a delicate balance of humanity and survival. Stephen Frears, an renowned director with some missteps, is on sure footing here. He maintains the tension of the characters' circumstances whlie trusting the leading actor to be the moral center of the film. Chiwetel Ejiodor is absolutey brilliant in his role of Okwe, an exiled Nigerian doctor, who stumbles upon a organ-selling scheme. Mr. Ejiodor imbues the charcter with a sense of non-judgemental righteousness that is just remarkable. Audrey Tautou is terrific as Senay, a young Turkish woman trying to get to New York. Her performance is very real. Sergei Lopez is an affable villain, his performance not unlike the work of Colm Meaney and Anthony Lapaglia. The line between right and wrong and the line between survival and self-interest are pretty close to one another.
