Corrected entry: In the scene where Lee and Kenji are fighting, a thug tries to sneak up from behind on Lee. Carter shouts a warning "Jackie!" using Jackie Chan's real name instead of his character name of Lee. (01:10:25)
Corrected entry: When Carter and Lee meet Kenji in the sewer scene and discuss that Lee and Kenji are brothers, when they start speaking to each other, instead of both speaking Chinese, Lee is speaking Chinese, and Kenji is speaking Japanese.
Correction: Just like in many movies where one character speaks one language and the other speaks another. They both understand each other but refuse to speak the other person's language. No mistake.
Correction: They're both speaking Japanese.
Corrected entry: In the scene after Soo Young's father is shot, she tells Tucker and Chan that her father mailed her an envelope, and that if anything happened to him, she was to give it to them. Tucker and Chan go in an attempt to retrieve the envelope from the karate school that Soo Young teaches at, only to find out that some men had already taken it (presumably the bad guys). However, the entire purpose of the envelope is never mentioned again. It couldn't have been the 'Shi Shen' list because it was tattooed on Genvieve's head. She also states that the list is always secretly tattooed on a woman's head. This indicates that the mysterious envelope had no other purpose rather than to implement a fighting scene for Tucker.
Correction: Genevieve asked Ambassador Han for help in exchange for information about the Triads. The envelope contained the information upon the list and the customs of the tradition. That's why they were going after Genevieve as well. Soo Young was supposed to give it to Lee and Carter because her father trusted them to stop the Triads.
Corrected entry: In the opening scene, when Carter is upset about the "1981 Cutlass Supreme" getting hit, the car shown (although briefly) is a 1980s model Monte Carlo. Notice the front end, longer hood, body lines, etc. The body style of an Olds Cutlass and Chevy Monte Carlo look similar, but they are in fact entirely different.
Correction: This is a character mistake. Many people misidentify cars, and Carter is not the most intelligent character in this film.
Corrected entry: When Carter and Lee are in the elevator after the sewer scene, the dog hikes his leg up on Carter and starts peeing. Lee looks down at the obvious boy dog and says, "Good girl."
Correction: Character mistake.
Correction: Actually, he just says "Watch out!"
