The true story took place in Pikeville, Kentucky, most famously known as the home of the Hatfields and McCoys. However, most of the film is set in Harlan County, Kentucky, in the Appalachian Mountains, which is most well-known as the setting of the FX series "Justified" (2010).
The 1994 TV movie "Betrayed by Love," starring Patricia Arquette, was based on this same case.
Made two years prior to its release.
Parts of this movie were filmed in Harlan and Paris, Kentucky. While not incredibly well-known, Paris was also the shooting location for "Seabiscuit" (2003) and "Secretariat" (2010).
Jack Huston from "The Longest Ride" is the nephew of Hollywood legend Anjelica Huston.
