Factual error: The first Kinetoscope (arcade of 'personal movie viewers') was opened in 1894 and the first motion picture studio was located in New Jersey. There is no way that they would have known enough about motion pictures in 1887 to go into them, let alone go to Hollywood to do so. And the use of the word 'movie' is at least twenty years too early.
Chon Wang: It's a puzzle box. I don't know how to open it.
Roy: What do you mean, you don't know how to open it? You just get a hammer and smash it open so you can see what it says.
Chon Wang: No. I must have patience. By the time I'm able to open it, I will be ready to read the message.
Roy: Oh, come on, Confucius, that's the corniest thing I've ever heard.
Trivia: The portrait of the young man under which Fann Wong hides was used again in another Jackie Chan film - "Rush Hour 3." This time, an assasin throws a knife atJackie and hits the portrait instead.
