Los Angeles: Hollywood star Reese Witherspoon has joined the cast of crime drama 'Devil's Knot', which is based on reporter Mara Levitt's 2003 book.
The 35-year-old Oscar-winning actress has signed up to appear in the film to be directed by Atom Egoyan, which is based on the book 'Devil's Knot: The True Story of the West Memphis Three', as reported.

In the book, Levitt followed the prolonged murder trial of Damien Echols, Jason Baldwin and Jessie Misskelley Jr, who served 17 years in prison before being released this past August. They were accused of killing three eight-year-old cub scouts found in a wooded area of Arkansas called Robin Hood Hills.
Witherspoon will play Pam Hobbs, the mother of one of the victims. The production of the movie is expected to begin next summer and as well as Egoyan and Witherspoon on board, Scott Derrickson and Paul Boardman will serve as the screenwriters.
