THE UNTOLD STORY is perhaps one of the most infamous of all the Category III thrillers made in Hong Kong, and certainly one of the films that helped to kick start a whole wave of sleaze and depravity in 1990s Hong Kong cinema. It's based on a true story that happened in Macau in 1985, in which a restaurant worker ended up butchering his colleagues. Two unconnected sequels were to follow, while star Anthony Wong find himself typecast in similar roles for the rest of the decade.

Given that this is an outrageous Hong Kong movie, everything plays out in an over the top fashion. There's one of the nastiest and most explicit rape sequences you'll ever seen, alongside some truly horrendous murder scenes which don't skimp on the visceral mayhem. A late-stage flashback depicting the murder of an entire family is particularly gruelling. Anthony Wong transforms himself into a crazed and frightening figure as the villain of the piece, while Danny Lee holds it together with his typical cop performance. I didn't like it quite as much as THE EBOLA SYNDROME, but it's certainly one of those films that gets in your head.

How do you think someone who is a horrible person should be treated? Furthermore is it enough to suspect that the person is horrible to treat him - actually abuse him is a better wording. Treat him sounds too nice. The sensibilities as Anthony Wong himself admits are different in Hong Kong and the "western World". If the police use brutality, even if we feel it may be called for ... we start to sympathize for a person who might not deserve that sympathy at all (sympathy for the devil and all).

The question that can also be asked, is that treatment exaggerating his own drive to violence? Going mad through abuse or was the madness always there and the abuse was nothing that could faze him? I've asked many questions and I don't think every one of them will be answered for most viewers or even answered the same way as stated above already.

But the movie is quite violent and harrowing. It is tough to watch and when it gets explicit (in many ways in its uncut form),some will not be able to stomach it. There is a reason this has an adult rating and there is a reason many scenes have been cut (no pun intended). Really good acting from great actors

In the opening scene, Wong Chi Hang (Anthony Wong) shows us his psycho killer credentials by beating his restaurant-owner boss senseless, dousing him in petrol and turning him into a human torch. He goes on to take control of the dead man's business, and continues to kill, literally making mincemeat of his victims, using them as an ingredient in his tasty pork buns.

When some mouldy body parts wash up on a beach, it is not long before the police are hot on his trail. They arrest him (but not until after he is able to dispatch of at least a couple more unlucky souls) and try to beat a confession out of him. He is eventually sent to prison where he suffers at the hands of his ex-boss's brother, who isn't too chuffed at the way his sibling ended up.

Anthony Wong is all crazy grimaces and manic stares, turning in a convincing portrayal of someone playing with a few cards short of a deck and his performance will stay with you long after the closing credits.

The film is certainly not for the squeamish - the gore is frequent and graphic and leaves a nasty taste in the mouth. Two scenes in particular push the boundaries of film horror – the rape and murder of Wong's female employee and the massacre of an entire family which features stomach churning scenes of children being butchered. These scenes seem even more hard to stomach when sandwiched between out-of-place (and not very funny) comedic episodes.

However, I cannot deny the punch that this film packs. Like with so many of the grittier horror films out there, it is hard to say I actually enjoyed the movie, but I was certainly impressed by its sheer verve and willingness to shock.
