The film is billed in the closing credits as: ''A Trenchard production''.
The film's director Brian Trenchard-Smith said of this title around 2010: ''Viewed 35 years later, KFK is a long trailer for Asian Cinema masquerading as a Documentary Special. Somewhat scrappy and heavy handed in places too. But now, with the advantage of 20/20 hindsight, it is a really interesting time capsule. Grant is engaging as ever, and the kung fu combats are lively.''
This documentary was made for television with a running time of 75 minutes for broadcast in a 90 minute time slot.
One of three early to mid 1970s filmed productions of Australian director Brian Trenchard-Smith which shot in Hong Kong.
