You can tell someone hurried and pieced this thing together before Chris Tucker changed his mind. As funny as he was in parts of this movie, no one should have gotten $20 million for this poorly-written, "avenge my father" flick.
The story is that Consul Han has found information that would destroy the Triad, a vicious Asian mafia. An assassination attempt on him fails and somehow that convolutes Inspector Lee and Detective Carter to once again unite.
From here, the plot becomes essentially meaningless. The movie becomes and excuse for Chris Tucker to throw a one-liner, Jackie Chan to throw a punch, and both of them to throw out the cultural differences. By the end of the movie you can't even believe the giant holes left. Why go through all the trouble to rescue one of the characters in a subplot, only for her to inexplicably disappear at one point? This was definitely one movie that resembled good Chinese food gone badly: about an hour after you watch it and thought you liked it, you end up feeling horrible about the experience.
I couldn't even tell you about the DVD extras because frankly I didn't care once I was done watching. The credits featured some funny gag outtakes, but even now those can get a little boring.
