The original director was John Powell and the budget was $150,000. Two weeks into the film in April 1978 the film was running into difficulties; $75,000 had been spent already and cheques to the crew were bouncing. Producer Allan Spiers called in Phil Avalon, who had just made a successful low budget film with
Summer City. Avalon looked at the budget, felt that $200,000 was required to finish the film, and succeeded in raising the additional funds from the investors, who he says were state government senators from Brisbane. Avalon negotiated with the actors to reduce their fees, which he felt were too excessive for a low budget film. Avalon says ninety percent of the cast agreed to do this. He then tried to do this with the crew, and several of them left, including the cinematographer. Unions threatened to shut down the film but Avalon managed to keep it afloat. Avalon hired
Terry Bourke, who had directed him on
Inn of the Damned, to rewrite the script and direct the rest of the movie with Powell. The rest of the film was completed in nine days. Steven Walls, who inspired the story, plays a small role as one of the men at the bar, who are asked to join in the search.
Johnny Ashcroft has a brief cameo as one of the searchers by the camp fire at night. Steven's grandmother and many of the original searchers acted as searchers in the movie. ==Release==
