The trial of the West Memphis Three has been the subject of several documentaries, including the Paradise Lost trilogy and 2012’s West of Memphis.  Now, director Atom Egoyan (The Sweet Hereafter, Chloe) brings us a dramatic retelling of the complicated and polarizing trial of the teenagers tried for the murder of three boys.

The new trailer highlights stars Reese Witherspoon as the mother of one of the murdered boys, and Colin Firth as a private detective who goes undercover to help prove the boys’ innocence.

Devil’s Knot is based off the true crime book by Mara Leveritt.  It’s due out May 9, 2014.
