This story is about a Hong Kong prostitute ("chicken" is slang for prostitute) who winds up trapped in an atm with a would be robber. To pass the time till power is restored, she tells her life story. This film is a Sandra Ng tour de force. She is great in this role, playing it to the hilt, having fun, enduring heartache and just being her. The movie is told in flashback and while its essentially a comedy there are some sweet, poignant moments. Tony Leung and Andy Lau give some good performances, but this is Sandra's film. I can't imagine this film being remade in the U.S. and that is a great thing. Over her career, Sandra Ng has shown incredible versatility in her acting. She manages to look pretty, sweet and funny, all in the same scene. She won the Golden Horse for Best Actress and she deserved it. Eric Tsang, as the would be robber, is fine, but you'll be blown away by Sandra's performance. Its nit a vulgar film, despite the plot. I highly recommend this film.
