With “After Death” (produced by Jason Pamer & Jens Jacob of Sypher Studios, the team behind “The Heart of Man”), it feels like the faith-based documentary is starting to come of age. The documentary explores the phenomenon of near-death experiences as conveyed by scientists, authors and survivors through interviews and dramatic re-imaginings of their experiences. The interviews include New York Times bestselling authors behind titles like “90 Minutes in Heaven,” “Imagine Heaven” and “To Heaven and Back.”
