The Chain Reaction

An earthquake in rural Australia causes a dangerous leak at WALDO (Western Atomic Longterm Dumping Organisation), a nuclear waste storage facility. Heinrich Schmidt (Ross Thompson) an engineer badly contaminated in the accident, knows that the leak will poison the groundwater for hundreds of miles around and wants to warn the public. His boss, however, is only interested in protecting himself and believes that the accident should be covered up, when in fact the contamination risks thousands of lives. Heinrich escapes from the facility but is badly injured. Lost in the woods and suffering from amnesia, he is rescued by Larry Stilson (Steve Bisley), a car mechanic on holiday, and his wife Carmel (Arna-Maria Winchester). As Heinrich tries to piece together his memories of what happened, his boss' thugs are quickly closing in on the trio.

A car chase sequence of The Chain Reaction.

The film was the idea of director Ian Barry. He had been talking to producer David Elfick about making a film called Sparks about a blind film director, based on a short film he had made, but Elfick thought the subject matter would be too difficult to finance. Barry had written another film, a thriller then entitled The Man at the Edge of the Freeway, and Elfick decided to make that instead. The movie was budgeted at $600,000 but the Australian Film Commission thought it was too high so it was re-budgeted at $450,000. George Miller came on the project as associate producer.[4]

Funding came from the Australian Film Commission, Victorian Film Corporation and Hoyts. Shooting started in September 1979 and took place in Sydney and Glen Davis, New South Wales.[5] Elfick says the location at Glen Davis was rumoured to be the site of an aboriginal massacre and was supposed to be cursed; he believed it because filming was extremely difficult.[4]

Filming took longer than expected and the movie went 40% over budget. Miller was tasked with directing the car chase sequences, which featured the Ford Fairlane LTD in most scenes as the preferred vehicle of the antagonistic authority chasing Larry's modified Holden HQ ute.[6] David Elfick also filmed some second unit.[4]

The film was shot with a widescreen anamorphic lens. Post production was reputedly very difficult with representatives from the AFC, VFC and Hoyts supervising and discussing every cut of the film.[5]

The film was released shortly after Mad Max and it has a similar theme to that film as well as American films like The China Syndrome in regards to the whole nuclear-apocalyptic storyline.[7]

The film was distributed in Australia by Palm Beach Pictures and Warner Bros. in the rest of the world and released on 25 September 1980.[8]

The music for the film was composed by Andrew Thomas Wilson.[9]

The web page TV Guide.com gave 3 out 4 stars.[12] In Yahoo! Movies, the users rating to the film with a C[13] and 5.5 out of 10 in Internet Movie Database.
