has joined the cast of Devil’s Knot in a lead role. The True Blood star will play prosecutor John Fogelman in the film about the wrongfully convicted and imprisoned West Memphis 3. He joins Colin Firth, Reese Witherspoon Alessandro Nivola and more in the cast and will begin work on the Atom Eyogen-directed film immediately to fit in shooting around his schedule for the HBO vampire series. Devil’s Knot tells the true story of how, despite no psychical evidence, teens Jason Baldwin, Damien Echols and Jessie Misskelley were found guilty and jailed for a triple homicide in 1993. They were finally released last year. The movie is based on the 2003 book Devil’s Knot: The True Story Of The West Memphis Three by investigative reporter Mara Leveritt. Moyer is repped by WME and managed by Lubor Roklin Entertainment.
