And yeah, it was more the vampires that I was looking to ID in 5
Oh what I wouldn't give for the Hong Kong film industry to have had a system in place then (and now for that matter) under which extras were given credit in films. Judging from their lengthy Chinese-text cast scrolls, many films did try to give credit (at least it seems that way) to entire casts, but with many other films, especially many of the lesser-known films of the crank-em-out 80's and 90's, we're lucky to have much beyond the principal cast itself!
But then, such requirements would probably only happen with the presence of unions, and then we wouldn't have a fraction of the HK films that are available to us from the past 40 years or more!
