Every seat full tonight at Little Rock's Ron Robinson Theater in the River Market for the premiere of "Devil's Knot," the new film based on the exhaustively researched 2002 book by Times contributing editor Mara Leveritt about the West Memphis Three case. The film focuses on the murders of Stevie Branch, Christopher Byers and Michael Moore, and ends just after the 1994 convictions of Damien Echols and Jason Baldwin. Oscar Winners Colin Firth (as private investigator Ron Lax) and Reese Witherspoon (as Pam Hobbs) star. We'll have a full review in next week's issue and online.
