I'm not sure how the Jackie Chan "porn" thing is even newsworthy, since he wrote about it in his English-language biography a few years ago. Somehow this smells like another attempt at "humble" publicity.
As for marking it Category III, did the rating even exist in 1975? With that cast, surely ALL IN THE FAMILY is more like a T&A comedy than any kind of "porn" film? Doesn't plain old nudity sometimes garner one of the Category II ratings?
And how exactly does Jet Li injure himself shooting a movie that's been out on DVD for some time now and is about to hit theatres in the days ahead?
