More ozploitation. Directed by Brian Trenchard-Smith (The Man from Hong Kong (1975)) using a script Peter Smalley derived from Peter Carey's short Crabs (circa 1974). The concept is that the state (?) turned drive-in cinemas into concentration camps for the economically useless. Really it's an excuse to update Mad Max to the mid-1980s conception of the apocalypse, one now decidedly urban.
The set is mostly cars, mostly 1970s classic wrecks (Holden shaggers, humongous Ford utes) excepting lead Ned Manning's brother Ollie Hall's 1956 Cadillac which is ridiculously pristine. (Actually the entire camp is remarkably clean.) Manning uses it to take squeeze Natalie McCurry to the drive-in but fails to realise the consequences of buying an "unemployed" concession ticket from Peter Whitford. He's keen to bust out but she prefers the hairstyles available in sheltered community life.
The strong themes (a white nationalism meeting seemed to get a 99.9% turnout) and weak plot prefigure Ben Mendelsohn's breakouts The Big Steal (1990) and Return Home (1990). This film's central flaw is that it lacks a star of his or Gibson's calibre. The early scenes are quite funny and a little cute as Manning jogs around a recognisable Port Botany while people take outre angle grinders to all sorts of things. The drive-in itself was apparently in Matraville. It looks like it was a fun and good-natured shoot.
Loads of details at Ozmovies. Tarantino's favourite of Trenchard-Smith's efforts.
