Heatwave is a 1982 Australian film directed by Phillip Noyce based on the murder of Juanita Nielsen.

The original script was called King's Cross and was written by Tim Gooding and Mark Stiles.

I don't know whether audiences realised that, but we had always assumed that he was a working-class Protestant and that Judy Davis's character was a middle-class Catholic girl.

She, in the Catholic saintly tradition, had adopted a social cause - had set herself up as the spokesperson and protector of the working class.

Heatwave belongs to a different era in Australian cinema, a time when we took a lot risks.
