Australian producer Antony Ginnane brought this $6 million romp to New Zealand, after Aussie union Actors Equity objected to the four lead roles going to foreigners. Deer hunting heroes Donald Pleasance (Halloween) and Ken Wahl (six years before becoming TV's Wise Guy) race around in helicopters and jet boats, after discovering a half-sunken WWll plane. This opening excerpt indicates the film's mixture of action, comedy and Southern scenery. Zephyr helped establish Aotearoa's reputation as a place to film; Ginnane and Kiwi John Barnett produced further projects together.
With Hunter's Gold, Gather Your Dreams and Children of Fire Mountain, Roger Simpson blazed a successful trail for Kiwi drama shows aimed at a younger audience. Though he has written further New Zealand projects, Simpson relocated to Australia in the early 70s. Since then he has written and produced on a long run of television dramas, most often alongside producing partner Roger Le Mesurier.
