Wong Jing’s On His Majesty’s Secret Service is as narratively unfocused and packed with non-sequitur scenes as any of the rotund Hong Kong film kingpin’s comedies, but here is the gist of its ‘plot’: an Imperial Guard (Louis Koo) with no martial arts skills but a gift for scientific innovation becomes embroiled both in his fiancée’s (Barbie Hsu) plot to make him love her more by pretending she’s in love with a handsome hitman who’s actually a beautiful hitwoman (Liu Yang), and in an evil eunuch’s (Fan Siu Wong) plot to overthrow the emperor (Liu Yiwei), who is organizing a competition to find a worthy husband for his daughter (Song Jia). Apart from lavish costumes and sets, the direction is lazy and uninspired, while the humor consists of constant and lazy pratfalls, obvious pop-culture references (some are even delivered while literally winking at the camera), some inscrutable (for non-Cantonese speakers) wordplay and a cornucopia of blissfully unhinged comedic acting: Louis Koo is a broad delight, Fan Siu Wong steals all his scenes with his ‘dainty evil’ act, Song Jia shows effortless comedic skills, and while Barbie Hsu’s silliness feels more forced and Sandra Ng seems on autopilot, Tong Dawei and Liu Yang provide fine serious support, the latter being particularly charismatic as a cross-dressing assassin. All in all, it’s a harmless and often amusing comedy which could have stood out more if its numerous action scenes had been choreographed and directed with more verve. **1/2
