Academy award winners Colin Firth and Reese Witherspoon have partnered up to play the leading roles in the upcoming horror film. It is based upon the 1933 true story of the death of three 8-year-old boys and teenagers known as the West Memphis Three who are accused of killing them. With little evidence tying the teenage boys to the murders, the townspeople believed supernatural powers may have caused the killings which took place in West Memphis, Arkansas in the U.S. The film will use the 2002 crime book written by Mara Leveritt called Devil’s Knot: The True Story of the West Memphis Three as the guideline for the film. It will premiere in US cinemas on May 9, 2014 with no UK date yet confirmed.
