Who invented "drunken boxing"?
Is it an existing, "real" fighting style, or is it made up just for this film (and its sequels)?
If so, is it Jackie Chan who came up with the concept of it all, the moves, stances, the nine drunken gods and all?
There are characters in fighting games (Tekken 3 and DOA, maybe more?) that use "drunken style", which might be a proof of it being an actual "real" fighting style, but on the other hand it may as well be taken as a proof of Drunken Master's (the movie's) cult status.
I mean, they do take a lot of liberties when making Kung Fu movies, pulling stunts and stuff that would never be humanly possible (or effective in combat) when attempted real life - so it's not impossible entire "styles", like drunken style, is made up... but does anyone know for sure?
