Other mistake: During the fight in the outdoor market, while Jackie Chan is trying to use a wooden box to defend himself from a villain, notice that the knife the villain uses bends like rubber as it hits the box. (00:30:00)
Shanghai Knights (2003)
1 other mistake - chronological order
Directed by: David Dobkin
Starring: Jackie Chan, Owen Wilson, Aaron Taylor-Johnson, Donnie Yen, Aidan Gillen, Tom Fisher
Factual error: In the scene after Chan and Wilson crash their car into Stonehenge they walk away and the view is of a field and a beautiful blue sky. In the sky you can see an airplane vapour trail up on the left hand side of the screen. There were no airliners in 1890. (00:58:50)
Roy: Just go ahead and drown me! I don't care anymore.
Trivia: When Roy is talking about his ideal life with Lynn, he mentions his three children, "Vera, Chuck and Dave," a very slick reference to the Beatles song "When I'm 64."
