As you might recall, Tracy Letts is writing an adaptation of a true life crime story for Natalie. You can get up to speed by reading this update from October.
Well, in this article, about the Pulitzer winning Letts, it mentions that he should be finished with the script by spring time.
We still don’t know if this is going to be something that Natalie acts in or just produces, but its definitely a project to keep an eye on.
