Alec talks with director Joe Berlinger about his latest film for HBO Paradise Lost 3: Purgatory -- the third film in a series of documentaries about a crime that took place 18 years ago in rural Arkansas.

Berlinger says, “We made these three movies as acts of advocacy” – which is not his usual style as a long-time documentary filmmaker. “I believe the audience should be treated like a jury. You give them the information, you weigh both sides, and you let them come to their own conclusion.” These films were different, acknowledges Berlinger: “We clearly have a point of view that there is a huge injustice.”

Early in his career, Berlinger worked for famed documentarians David and Albert Maysles. He says the Maysles brothers taught him about “The act of faith about making a film about real life as it’s unfolding.” Berlinger is known for his documentary work, has dabbled in features, but says he’d “love another opportunity to do a feature at some point, but, you know, I’m just used to being the author of my own work, being totally in control.”
