Hi Mike, Rose, and Pen
In the words of young Mr Grace, "You've all done very well!"
Rose, I was interested to read about Tom Brown(e), the man behind the pseudonym. A remarkably interesting man.
Mike and Pen, you’ve both picked up on the 1957 movie. Another budding actor in that movie was the man who played Illya Kuryakin in Bob’s your Uncle.
I would have also accepted any of bushranger Captain Starlight (Sam Neill), Ben Marston (Ed Devereaux), and Ben's two adventure-hungry sons (Steven Vidler and Christopher Cummins)as the male leads.
or the females: Liz Newman as Gracey, Jane Menelaus as Aileen, Deborah Coulls as Kate, Susie Lindeman as Jeannie, Elaine Cusick as Mum.
Two versions of this 1985 remake were shot simultaneously – a feature film and a TV mini-series.
