The Untold story tells the true story of a serial killer cook, although this version of the story is the type you might find within a dirty copy of a sleazy gossip rag in the trash of a smelly bus station bathroom.
The film though is acutely aware of this as it goes for pure exploitation here. The film would be like if in Zodiac you spent half the film watching Mark Ruffalo and Anthony Edwards ogle their boss’s girlfriend and mock their female coworker for her lack of ample breasts. That's half the film as the investigators are portrayed to be utter buffoons in sequences of rather broad comedy. In rest of the time, we are with Anthony Wong, which are even more ridiculous if you can believe it, despite winning the Hong Kong Film Award for Best Actor that would be like if Terry O'Quinn won the Academy Award for The Stepfather. Here's the thing though as proven by his work in Hardboiled, Infernal Affairs, and especially Beast Cops Anthony Wong is a higher caliber of actor. He's not a simple exploitation actor in terms of talent, which means he offers a little more than you might expect. That's not to say Wong gives this serious performance, quite the contrary, Wong knows the type of film he's in and he embraces it to its fullest.
