The film was an original story by writer Everett De Roche, who said he got the idea from a neighbour of his in Mount Isa. It was based on a true incident about the war-time disappearance of an American DC3 military aircraft carrying the payroll for the Pacific fleet which was later discovered off Cape York. Richard Franklin was originally attached as director, and Antony I. Ginnane produced.
The script was originally set in Queensland, Australia, but the producers wanted to import four overseas actors, and Actors Equity objected. De Roche re-wrote the film so it was set in New Zealand. Richard Franklin dropped out of the film because he was unhappy with the change in location, and David Hemmings, who was attached to the film as a producer, was appointed director.
Funding was obtained privately.
The film was one of the leaders of Soviet film distribution in 1983, when it was seen by 29 million Soviet viewers.
Ginnane was so annoyed with Australia's Actors Equity that he made his next four films in New Zealand.
