Hong Kong can boast a very rich cinema history which is largely centred on its very successful martial arts movies.
But it has also produced films which are dark and complex such as Dante Lam's fearsome thriller That Demon Within.
This is a movie which sets out to unsettle its audience as well as staying just ahead of any attempt to work out its denouement,
It stars Daniel Wu as an insular and unpopular, do-it-by-the book cop who unwittingly saves the life of a gang leader Hon Kong (Nick Cheung) by donating his blood.
Hon is a ruthless archetypal villain but Wu's cop is anything but stereotypical.
He is a loner who has faced an abusive childhood and literally beats himself over his own inadequacies.
And now they have the same blood!
In common with many films from the Far East, That Demon Within is relentless. Its violence is merciless and graphic and the pace at which it zips through its storyline never slows down.
But, despite the mayhem, there is still time for Wu to show his range with a character who struggles to draw the line between right and very wrong.
This film is on tour across art house cinemas in the UK over the next few weeks. Fans of Far Eastern cinema should not miss out.
