Polygamy movie based on Carolyn Jessop's story

She announced in 2008 that she was going to be starring as the author of the book "Escape", Carolyn Jessop but nothing has happened on it. I thoroughly enjoyed Carolyn's story and was excited to hear it would be a movie.. so if it has stalled I hope that means that they would recast Katherine's role in this as I don't think she would fit very well
