Silly question but...if Kingdom Yuen isn't in the film, why is she creditted in the cast list? At the very bottom it says "Yuen Lai King" as "Operator" and directly above that there is the Chinese characters for Kingdom Yuen King-Tan's name, ala...

...my DVD copy of this film has been delayed by Customs, so I won't receive it for a few days -- thereby I can't give visual confirmation of Yuen's presence in the film; but she's certainly creditted as being in the film in those end credits you've provided!
NB: Wong Yat Fei is also creditted, in the screengrabs you've provided, as "Wong Kai Yue"...go figure...
