I don't think there is a dubbed english version. I hope there isn't and there never is, 'cause as has been mentioned the jokes wouldn't translate very well.
The only part I really didn't like about the movie was when the girl got her "makeover". She looked like a poorly-done 1980s store mannequin. It was just ugly. I could not believe that was supposed to make her look good.
A friend pointed out that this movie is like Dragonball Z meets Soccer, except without the 4 hours of grunting, groaning and posturing where maybe 5 punches are thrown. I think he's right.
By the by, does anybody know if/how the actor who plays the villian is related to Jackie Chan? I'm pretty sure he is; he has a strong family resemblance and I saw the name "Terry Chan" in the mostly-cantonese credits. (The character name was in ideograms unfortunately)
