The West Memphis Three case is coming to the big screen in "Devil's Knot," and a new trailer for the film has just been released.
The film, based on Mara Leveritt's book "Devil's Knot: The True Story of the West Memphis Three," centers around the brutal murders of three young boys in Arkansas in 1993 and the three teenagers who were accused of killing the children as part of a satanic ritual.
Reese Witherspoon stars as the grieving mother of one of the victims, while Firth plays a private investigator who is not convinced the teens are guilty of the crime.
Directed by Atom Egoyan, "Devil's Knot" also stars Dane DeHaan, Amy Ryan, Mireille Enos and Stephen Moyer. The film will be released in theaters on May 9.
