Jackie Chan and Owen Wilson re-team for Shanghai Knights, the sequel to their 2000 comedy adventure, Shanghai Noon. In the first movie, Chon Wang (Chan), a fish-out-of-water Imperial Guard from Chinas Forbidden City, teamed up with ad-libbing outlaw, Roy OBannon (Wilson) in Americas Wild West to track down a kidnapped Chinese princess. This time, however, both heroes wind up in the dark and unfamiliar backstreets of Victorian London.
Chon discovers that an English aristocrat called Rathbone (Aidan Gillen) has killed his father in an attack on the palace during which the Emperors jewel-encrusted Imperial Seal has been stolen. Seeking revenge, Chons sister, Lin (Fann Wong), has followed Rathbone to London and now Chon asks his pal, OBannon to travel there with him to stop the killer from carrying out his other nefarious schemes. As it happens, Rathbone is tenth in line to the British crown, but he intends to hasten the exits of the other nine with the help of some Chinese cohorts, including Wu Yip (Donnie Yen), the Emperors illegitimate brother, who has big plans for his own country.
Introducing a little friction into the proceedings and widening the cultural gap a little more between the boys is OBannons romantic interest in Chons sister, but thats about as serious as things get. While comic moments and kung fu action fly thick and fast, the movie has fun introducing totally anachronistic film and music references including a nod to Singin' in the Rain that occurs during one of Jackie Chans imaginative fight sequences. There is also the appearance of real-life characters of the period such as Jack the Ripper, Charlie Chaplin and a cluey Scotland Yard detective known as Artie Doyle - read: Arthur Conan Doyle - to add more colour to the lively plot.
