Robert Baker's brother works for the West Memphis, Arkansas Police Department.
Based on the 2002 book "Devil's Knot: The True Story of the West Memphis Three".
Feeling the movie had limited commercial value, the distributor decided to give it a very limited release, resulting in the movie being a box office disaster.
