Missing subtitles

Just to make people aware that though the Uk version of the actual fim has english subtitles, the bonus extra Making Of featurette, doesnt. I found out much to my dismay as i dont speak chinese and really wanted to know what was being said. It looks v interesing. At over 20 minutes,its also a large chunk of the bonus material. I cant figure out why there are no subtitles as the other bonus material does have them. Did someone forget when it came to the documentary?! Who knows!
Though i thought the film enjoyable, this omission let down the dvd package as a whole.
