The Tale of Ruby Rose is a 1988 Australian film written and directed by Roger Scholes, produced by Andrew Wiseman and Bryce Menzies, and starring Melita Jurisic, Chris Haywood, Rod Zuanic, Sheila Florance, and Martyn Sanderson.
In the wild and isolated wilderness of the Tasmanian highlands, Ruby Rose is overcome by her fear of darkness.
The character is based on a story told to Roger Scholes by an old woman, Mrs Miles of Mole Creek Valley.
As a young woman, she had lived alone in a hut in the Highlands for four years, without knowing that her husband had died while trying to get back to her in the middle of winter.
By this stage in the movie the audience is fully aware of Ruby's mental instability and her terror of the dark.
