The Plumber, 1979
Jill (Judy Morris) lives with her husband, Brian (Robert Coleby) on a college campus in Adelaide. Judy spends her days working on her Master's thesis while Brian works in a research lab. One day a man, Max (Ivar Kants) shows up and tells Jill that he's been sent to work on the plumbing in their bathroom. Only his "repairs" seem to be more of a slow-motion demolition of their bathroom, and he begins to play some unsettling mind games with Jill. Jill slowly begins to go mad as no one will believe her about the sinister nature of the man who only seems to show up when Jill is alone.
There's a lot to unpack in this film in terms of gender and social class dynamics. It is an incredibly uncomfortable film to watch for most of the run time.
And to be honest, I just had a scary (as in calling 911) encounter that has kind of blocked out the thematic components of the film. I don't think I can even write very many coherent thoughts about it right now, because my anger on behalf of the main character is being strongly amplified by my own experience. I may revisit this one in the future to be able to give more of an actual review.
I do think the film does a good job of showcasing Peter Weir's ability to mix the surreal and the intimate.
