- Similar enough so that you can be assured of getting what you want
- Numerous enough so that you haven't seen them all
- Not so great that you'd be likely to watch them if they weren't in the category
Chow made 2 of the greatest comedies ever: Shaolin Soccer and Kung Fu Hustle. He also made a lot of other movies. Forbidden City Cop is one of them.
Chow plays a secret policeman protecting the emperor. But he doesn't have any kung fu skills, he wants to be an inventor. He goes out undercover as a gynecologist, but he is happily married to Carina Lau. So, goofy martial arts, silly inventions and a very sweet romance.
Nowhere near as good as SS or KFH. Maybe funnier in Chinese, or if you know all of the references. For ex, there's an extended James Bond riff in the credits. But, wait - I got that reference, and it wasn't all that funny.
Still, good for laughs and the romance is quite sweet. Carina Lau seems to be a decent actress as well as being very pretty. No great acting required here, though.
Also, she is Tony Leung Chiu Wai's girlfriend.
In conclusion, there's still 3 or 4 of these in my queue, and I'll probably watch them when I don't have any better ideas.
