Sporting one of the most humorous titles around, this film -- directed by David Chung Chi-man -- is an unlikely sci-fi Christmas flick. The film opens with a nefarious band of Japanese criminals putting a powerful explosive that they swiped from a mad scientist and in a can of Sarsae cola. Of course, the can gets lost amid a cornucopia of non-explosive beverages. Through an unlikely string of madcap events, cabbie Steward (John Sham Kin-fun) and bicycle enthusiast Cat (Maggie Cheung Man-yuk) find themselves chased by a host of killers believing that they know the whereabouts of the can in question. ~ Jonathan Crow, Rovi
