Here is a teaser for a panel that is part of HBO’s January 12 premiere of Paradise Lost 3: Purgatory, the final installment of the documentary that Joe Berlinger and Bruce Sinofsky made on the West Memphis 3. The trio was finally released this year after spending nearly 20 years in prison for murder after being convicted with no physical evidence and much inflammatory innuendo. While many people helped the defendants over the years — Peter and Fran Jackson, who’ve disclosed they paid legal bills, produced their own documentary — it was Berlinger and Sinofsky’s HBO documentaries that served as a continuing reminder that the trio was rotting in a cell for crimes the filmmakers didn’t believe they had anything to do with. Here’s a bit of footage from the New York Film Festival screening in what was the only time the three men had been together since they left the courthouse after their release. The entire Q&A can be seen on HBO.com.
