I saw this last month at the 2008 Palm Springs International Film Festival. The title of this film I believe is Munto not Moon To as listed here on IMDb and this Munto film is not to be confused with the Japanese animee movies of the same name. This is a gangster thriller set in Hong Kong. Nick (Daniel Wu) has spent his entire police career infiltrating a major drug organization led by Kwan (Andy Lau). Nick went straight from the police academy to undercover work and has never worn a uniform or even been inside a police station. For the past seven years he has worked his way up drug lord Kwan's organization that he is in a position to be Kwan's heir to his drug empire. Kwan, in fact, has selected Nick as his heir apparent because he is dying from the long-term results of diabetes. In the meantime Nick has been living in an inner city apartment where his next door neighbor Fan (Zhang Jingchu) is a pretty single mother whose low level drug dealing, heroin addicted husband (Louis Koo) drifts in and out of her and her daughter's life when he isn't in jail to pimp her out. Fan has also become a heroin addict. Nick develops a relationship with Fan and acts as a surrogate father to her little daughter. Nick has also become very close to Kwan. Thius is a good story from writer/director Derek Yee. Within the story line, it takes us to Burma and Thailand and complete with charts and graphs, almost becomes an educational anti-drug documentary on the workings of the Asian heroin trade within the Golden Triangle. Excellent cinematography by Keung Kwok-man and editing by Kwong Chi-Leung. Good production design by Yee Chung-man with Academy Award nominated costume designer/art director Chung Man Yee on board as a consultant. Fast-paced original music score by Peter Kam. This is a good movie and I would give it a 8.0 out of 10 and recommend it.
