Why it’s #2: If The Untold Story is horror, Ebola Syndrome is black comedy turned inside out. Also starring Anthony Wong as "Kai," a disgusting, misanthropic fugitive who contracts the Ebola virus and deliberately spreads it.
Note: Do not confuse this with the 1993 film. This earlier movie is the actual direct adaptation of the Macau murders. While less polished than the Anthony Wong version, it is historically vital.
These films are not for everyone. They contain genuine animal cruelty in some earlier titles (avoid Men Behind the Sun if that upsets you), simulated (and sometimes unsimulated) sex, and levels of gore that dwarf Saw or Hostel. The cat3movieus top list is a badge of honor for the extreme film completist.
But for those willing to look into the abyss, you will find a uniquely Hong Kong perspective on crime, punishment, and the grotesque.
Start with Dr. Lamb (it has a plot). Graduate to The Untold Story (it has a pork bun). Survive Ebola Syndrome (good luck).
Happy hunting, and keep your eyes on the uncut imports.
