A guy on YouTube saw the clip and told me that his mum played Edith in the original film Picnic at Hanging Rock. So I sent him a copy.
This is what he said;
Mum almost died laughing when the shy prisoner was carried off "MIRANDA DONT GO!!!" and screamed. Her reaction was typical. while finding it difficult to breathe "Put some effort in girl". Whole family loved it.
Apparently she lives in South Australia now "Christine Schuler now known as Christine Lawrance. She studies theology at the Adelaide College of Divinity."
Considering I sent it to Peter Weir, Leigh Whannell and gave one to John Waters it's good to finally get some response from the film world.
