Chiwetel Ejiofor stars as a disgraced doctor-turned-immigrant cab driver who inadvertently stumbles upon London's black market organ trade. Audrey Tatou and Sophie Okonedo also star as fellow "illegals" struggling to make ends meet in the shadows of England. This film is about illegal immigrants, it is told from their perspective, and because of that it becomes so humane that it indulges in social commentary. It's a really interesting, sometimes thrilling, watch.
One of those movies which are actually good for your education; think of it as a book you can read in two hours. It is, however, a very well-cast and well-filmed book. Hotel Rwanda is brutal and disturbing, which is only reasonable since it tells the story of one of the most horrific times in recent history. Led by an astonishing performance from Don Cheadle, it is overwhelmingly sad but an absolute must-watch.
