This news item is a bit confusing. It comes from an article about author Gregg Olsen, in which right at the end of the piece it mentions:
Olsen is already hard at work on his next piece of fiction, a black widow white-knuckler to release next year. “Starvation Heights” has been optioned as a motion picture, with Pulitzer Prize winner Tracy Letts adapting it to script and Natalie Portman attached to star.
Well, we know Tracey Letts is adapting something for Natalie but we believe its The Fabulous Fraudulent Life of Jocelyn And Ed. Perhaps Letts is writing more than one script for Natalie, but I’m pretty certain that someone has messed up with that article because when I asked around about Starvation Heights I got nothing but head scratching.
