Some comments here on IMDb have likened Dog Bite Dog to the classic Cat III films of the 90s, but although it is undoubtedly brutal, violent and very downbeat, this film from Pou-Soi Cheang isn't really sleazy, lurid or sensationalist enough to earn that comparison. However, it still packs a punch that makes it worth a watch, particularly if gritty, hard-edged action is your thing.<br /><br />Edison Chen plays Pang, a Cambodian hit-man who travels to Hong Kong to assassinate the wife of a judge; Sam Lee is Wai, the ruthless cop who is determined to track him down, whatever the cost. With Wai closing in on his target, Pang will stop at nothing to ensure his escapeuntil he meets Yue, a pretty illegal immigrant who needs his help to escape her life of abuse.<br /><br />A relentlessly harsh drama with great cinematography, amazing sound design, a haunting score, and solid performances from Chen and Lee (as well as newcomer Pei Pei as Pang's love interest), Dog Bite Dog is one for fans of hard-hitting Asian hyper-violence (think along the lines of Chan-wook Park's Vengeance trilogy). Stabbings, shootings, merciless beatings: all happen regularly in this film and are caught unflinchingly by director Cheang.<br /><br />Of course, this is the kind of tale that is destined to have an unhappy ending for all involved, and sure enough, pretty much everyone in this film dies (rather nasty deaths). Unfortunately, there is a fine line between tragedy and (unintentional) comedy, and in its final moments, Dog Bite Dog crosses it: in a laughably over-dramatic final scene, Pang and Wai are locked in battle as a pregnant Yue looks on. Eventually, after all three have suffered severe stab wounds during the fracas, a wounded Pang performs a DIY Ceasarean on (a now dead) Yue, delivering their baby moments before he himself dies.<br /><br />Whilst this film might not be a 'classic' slice of Hong Kong excess, with its deliriously OTT action and stylish visuals, it's still worth seeking out.
