Matt Birkbeck’s book A Deadly Secret: The Bizarre and Chilling Story of Robert Durst has the most Lifetime-movie title possible. So it makes sense that Lifetime would option it to develop as one of their signature original-movie events. The network just picked up the print property so there are no more details beyond the fact that some creepy soul will be cast to play Robert Durst in a story that will be told from the perspective of his late wife, Kathleen Durst, whom he may have murdered. The script will be written by Bettina Gilois, who received an Emmy nomination for her work on HBO’s Bessie. The news comes as Durst awaits arraignment in Los Angeles for the alleged murder of Susan Berman, a former close confidante of his.
