Arguably the funniest of the four famous Hui brothers, Michael has a tour-de-force vehicle in this naughty little comedy playing four different characters, each one in a compromising situation. And the laughs do come big and hearty as Hui bounces his cheeky humour off a terrific large supporting cast including the sophisticated Hu-chin and the lovely Pai Hsiao-man. Keeping the Benny Hill-style hi-jinks afloat is stalwart Shaw director Li han-hsiang who manages to switch flawlessly between these cheeky flings and his period epics.
