Dirty Pretty Things
Dirty Pretty Things is a thriller set in a hotel and deals with London's underworld. It is directed by Stephen Frears (The Grifters, Dangerous Liasons) and features Audrey Tatou (Amélie) who plays Senay.

"Okwe, a kind-hearted Nigerian doctor, and Senay, a Turkish chambermaid, work at the same West London hotel. The hotel is run by Senor Sneaky and is the sort of place where dirty business like drug dealing and prostitution takes place. However, when Okwe finds a human heart in one of the toilets, he uncovers something far more sinister than just a common crime." -- Summary by Sujit R. Varma taken from IMDb.com.
