This obscure Peter Weir TV movie from the late 1970s is a little dated, but still very entertaining and suspenseful. The three main actors (Judy Morris, Ivor Kants and Robert Coleby) aren't exactly household names here in Australia but will be familiar to most TV viewers over the age of 30 for their roles in various soap operas and the like. All three are excellent here in what could be their best work. Morris and Coleby play married academics. Coleby is distracted and concerned about an exciting career opportunity, Morris is currently working at home engrossed in her studies of New Guinea culture, and is timid and less confident socially than her husband. One day the plumber (Kants) arrives at their flat, and from then on her life will never be the same again. Kants is charming but rough, and very odd. A Dylanesque folk singer with a "Liberals = less tax" message on the back of his jacket (Non-Australians note the Liberal Party is our equivalent of the Republicans in the US or Conservative Party in Britain), he plays mind games with Morris, who becomes increasingly uncomfortable, and ultimately terrorized. Weir keeps things quite ambiguous and we never really know whether Kants is a dangerous psychopath or just the biggest pain-in-the-arse you could ever wish not to meet. I enjoyed 'The Plumber' a lot, it's a very effective low-budget, low key thriller shot through with plenty of black humour.
