Sony Pictures is at the helm, and producers there "are desperate" for Mara to play Knight, a source told the New York Daily News.
“They feel that Kate would be able to capture Michelle’s vulnerability and psychological pain — something she excelled at as Zoe Barnes."
(It appears Mara hasn't officially signed on, only that she's the current favorite).
The report also says that producers are looking for a "reasonably known" TV actor to portray Ariel Castro. A short list includes Breaking Bad's David Costabile, who weirdly looks the part, and Emilo Estevez, who does not.
On May 6, it will have been a full year since Amanda, Gina and Michelle were rescued, and their story became an international sensation.
