Film review: Dragon (15)

According to this chopsocky drama of twisted patrimony, "Only physiology and the law don't lie."

Debatable at the very least, though the film gives a pretty full account of what happens to the internal organs when a well-aimed blow is landed on the body.

Know anything of the vagus nerve? You will after this, and perhaps also marvel at the way a character seemingly struck dead can all of a sudden spring back to life.

Donnie Chen plays the gentle family man and papermaker whose real identity is blown when he's forced to defend his village from two violent clansmen.

Takeshi Kaneshiro is the police investigator who first twigs that the papermaker isn't all he seems. The fight scenes are so-so, the medical lowdown on body wounds the most intricate since Three Kings.
