In the scene where Chon Wang (Jackie Chan) fights Rathbone's guards, they are constantly making sure that no priceless antique urns are broken. This is the same action by Jackie Chan's character in the climax of Rush Hour (1998).
During the fight with the ruffians, Chon Wang (Jackie Chan) falls into a coffin. The sign on the wall behind him reads "Sowerberry". Mr. Sowerberry is the Funeral Director and Mortician from the book Oliver Twist by Charles Dickens. During this scene, the first four notes of the theme to The Addams Family (1964) are heard.
When Chon Wang (Jackie Chan) and Roy O'Bannon (Owen Wilson) are entering the Jubilee party, the string quartet plays an uncredited baroque version of the Rolling Stones' "Paint it Black" (just before the piece by Boccherini).
When Artie Doyle tries to break the lock of Madame Tussaud's, Roy compares his work to that of a surgeon. This is probably a reference to the fact that the real Sir Arthur Conan Doyle was a physician, even though in the movie he's a detective.
When Roy is fantasizing about his future family life, he mentions his kids' names as "Vera, Chuck, and Dave". These are the names of the grandchildren in Sir Paul McCartney's fantasy from the Beatles song, "When I'm Sixty-Four".
When Chon Wang (Jackie Chan) and Roy O'Bannon (Owen Wilson) are crossing the street in London, Wang pulls Roy back before he is hit by horses pulling a carriage. Roy says "Hey, I'm walking here!", a reference to Midnight Cowboy (1969).
The scene where Wang gives Artie Roy's watch to see what can be learned from it is a direct allusion to Sir Arthur Conan Doyle's "The Sign of Four" when Watson gives Holmes his watch to see what the great detective can induce from it.
Artie Doyle looks nothing like the real Sir Arthur Conan Doyle, who was a plump man with bushy mustache. However, Artie does possess a striking resemblance to Sherlock Holmes, especially according to the famous Sidney Paget's illustrations.
At some points, Lord Rathbone (Aidan Gillen) and Wu Chow (Donnie Yen) speak in iambic pentameter. Most notable is the stable scene: "I was taught to be neither seen nor heard/ Where is the seal? (I'm a man of my word.)"
Director David Dobkin had a difficult time choosing a suitable Asian actress who could do movement work, emote well, and speak decent English. He then saw clips of Fann Wong's videos Wo lai ye (2001) and Legend of the Snake Spirits (2001) and requested to audition her in London, which she did attend. She subsequently got the role and her number of scenes was increased by thirty percent.
When Chon Wang (Jackie Chan) meets Roy O'Bannon (Owen Wilson) at the Ritz, the music playing in the background is the music used as background music in The Little Rascals and other Hal Roach talkies; it is called "In My Canoe".
Alison King, who has become known for playing Carla Connor on Coronation Street (1960), appeared as a prostitute in the short scene when Owen Wilson was in the bedroom and answered the door inside an adult building.
Shot largely at the Barrandov Studios outside Prague in the Czech Republic with a predominantly British crew, filming was frequently held up as it was in the midst of a World Cup. The crew would disappear for 90 minutes to watch the English home team matches, much to director David Dobkin's bemusement.
Philip St. John Basil Rathbone (1892-1967) played Sherlock Holmes in the motion picture series between 1939 to 1946 including 'The Hound of Baskervilles' and 'The Adventures of Sherlock Holmes'. The success of which led to Rathbone being typecast and forcing him to end his employment at MGM and briefly return to Broadway.
Fann wong wasn't originally suppose to play the role of Jackie' s sister in the movie, Faye Wong was suggested by jackie but there was a mistranslation in the names by the assisstsnt director, she was given the role because jackie couldn't say no to anyone
