Natural Causes is a 1985 Australian television film about ex-hippies having a reunion. It is the first in a series of ABC telemovies showcasing Australian talent.
Barbara Hooks in the Age says "Although it teeters on the brink of the preposterous before recovering its balance towards the climax. 'Natural Cause' is brimming with serrated dialogue (underlined by evocative snatches of '60s and '70s music) deftly delivered by a keen and perceptive cast" In The Age's Green Guide Jason Romney wrote that Natural Causes "is a real mean martini, a blackly comic concoction with tight scripting brought alive by good editing and fine performances."
Sydney Morning Herald's Jacqueline Lee Lewes says "Natural Causes, written by John Misto and produced and directed by Michael Carson, is a clever and original black comedy. It is almost a gem, in fact. Unfortunately, Misto presses his luck and at times the humour is overworked."
