The laughs swirl around strong performances by Anita Mui, Sammi Cheng, and Cecilia Cheung.
Anita Mui plays the Emperor Qi(yes, that's Emperor), a lecherous, weak, cowardly fool whose destiny is to marry the infallibly virtuous Chung Mu Yen, played by Sammi Cheng. Of course things aren't that easy because a mischievous, but innocent Fox Spirit (translated in the subtitles as Enchantress), played by Cecilia Cheung, has fallen in love with Mu Yen instead.
The Fox Spirit curses Mu Yen by placing a large mark on her face, hoping the shallow Emperor's rejection of her will drive Mu Yen to love him instead. When that doesn't work, he turns himself into a beautiful woman to seduce the all-too-willing Emperor and drive Mu Yen away.
There really isn't a good reason why Anita Mui, as opposed to a male lead, was cast as the male Emperor, but somehow it works. She also plays the Emperor's Great Great Great Great Great Ancestor, the royal family's incompetent guardian spirit.
Adding to the fun are the Emperor's four flustered advisors, who record his mishaps in grand prose (a la Robin's Minstrels from Monty Python and the Holy Grail), and this film's low budget production.
A few of the script's lightning fast puns eluded the subtitlers and will elude a non-Canto audience. but there's more than enough fun energy in this film to make it worth seeing.
