please, add:

story: TSUI HARK. (and not co-writer) Hey I know what you are going to telling me: "In my videotape he appears as co-writer" OK, there are two versions of the credits, the international (in english) and the cantonese (in chinese and english). In the first version he is credited as co-writer, but in the cantonese (i presume this is the good one) he is credited as "story writer" both in english and in chinese)... I promise you

ALSO: producer: TSUI HARK.

I also don't know how mr. Tsui is in your credit list as "co-director". I did'nt see him as "director" in the film credits. May be he has to be put as [uncred.]

My guess is that if you wanted to be less specific, you can say that everybody who helped write the movie is a writer. Hitting the nail on the head, you would say he's a co-writer. I would leave at as is unless somebody else has a say...

maybe you are right. Excuse me.

but... co-director?

and producer
