'My one hour documentary World Of Kung Fu (1973) was a ratings success for the Seven Network, so I quickly sold a sequel concept to Channel Nine, this time 75 minutes for a 90 minute slot. The film would follow Australian stuntman Grant Page going to Hong Kong to learn more about kung fu, and to find who would succeed the late great Bruce Lee as Asia's top martial arts star.
A one page sizzle sheet, and my relationship with the Nine Network (for whom I had previously been the on-air promo producer before starting my own production company) was enough to get me a verbal acquisition deal from Nine's Len Mauger. In those days an executive's word was his bond.' (Introduction)
