Actress Kate Mara is reportedly in talks to portray Ohio kidnap victim Michelle Knight in a TV movie.
Knight, Amanda Berry and Gina DeJesus hit the headlines last year, when they were rescued from their Cleveland captor's home after a decade-long ordeal, when a neighbor heard their screams for help.
Knight, who was sick Ariel Castro's first victim, claimed she suffered five miscarriages while she was held captive, and producers at Sony have been keen to adapt her desperate story ever since the dramatic rescue.
A source tells the New York Daily News, "They feel that Kate would be able to capture Michelle's vulnerability and psychological pain."
They are also looking to cast a "reasonably known TV actor" to play Castro and are reportedly considering Lincoln's David Costabile and Emilio Estevez for the kidnapper role.
In August, Castro was sentenced to life plus 1,000 years in prison, but he committed suicide by hanging himself with a bed sheet in his cell the following month.
