I wonder how they did that. After this lead-in, we get to the real plot, such as it is. Wesley was apparently put on the case because he looks so darned Chinese. There is a great deal of running around. You'll be happy to hear that it's entirely possible to jump down a thirty-foot vertical distance without getting hurt, without missing a beat, and without the normal laws of physics applying to you.
Broken glass looks cool, rain looks cool, and leather looks cool.
In other movies, young ladies take showers for reasons not related to the plot. Here, our hero visits a Chinatown topless club for reasons not related to the plot. Since there was absolutely no reason for him to go to the strip club, he doesn't learn anything there that he didn't already know, and nothing that happens there advances the plot, the club appears to be in the film in order to demonstrate to the doubting world that Oriental women do, in fact, have nipples. It's necessary to do this because when Wesley makes his Oriental sidekick undress and throw all her clothes out of the passenger side window of a car, she manages to do it without revealing whether she has nipples. I wonder about people who are hiding out from Evil Villains seeking them in New York City.
