Ching is an cocky, under-achieving crook that ends up in prison, where he meets an old man who schools him in a prison kung fu duel. However the old man is sufficiently impressed with Ching as to give him half of a wooden amulet. The other half is possessed by a fellow inmate, and the two go off on a rollicking kung fu adventure to find an ancient scroll.
Monkey Kung Fu delivers fast paced action in a variety of backdrops - courtyards, mountain meadows, and tea houses where the furniture is predictably, and satisfyingly, reduced to firewood. And the brothel full of kung fu prostitutes was pretty fun. While most of the comedy is cheesy, there are so good one-liners ("Are you tired yet"? "No, I have a date with your sister tonight!"), and it keeps the movie light and entertaining.
The fight choreography starts off not too good in my opinion - moves kind of choppy and slow - but by the 38 minute mark, during the fight in a courtyard, it improves vastly. By the end, with a frenetic fight to the death in the mountains with a skilled bo (staff) master, it is some of the best in the genre. Very much recommended.
