An updated list of the Cast:

Jimmy Wang Yu - Fang Sing Ling
George Lazenby - Wilton
Roger Ward - Bob Taylor
Hugh Keays-Byrne - Sgt Morrie Grosse
Sammo Hung - Chan (Drug Courier)
Ros Spiers - Caroline Thorne
Rebecca Grilling - Angelica
Frank Thring - Willard
Peter Armstrong - Wilton's Bodyguard

I also think the theatrical run details are currently incorrect.

Updated.

Thank you.
