The Unbelievers (BD) (Blu-ray)

What are you willing to believe? "The Unbelievers" follows renowned scientists Richard Dawkins and Lawrence Krauss across the globe as they speak publicly about the importance of science and reason in the modern world. Blasphemous to some, heroic to others, the weight of their message is impossible to ignore. The film includes interviews with celebrities and other influential people who support the work of these controversial speakers, including Ricky Gervais, Woody Allen, Stephen Hawking, Sarah Silverman, Bill Pullman, Werner Herzog, Bill Maher, Stephen Colbert, Tim Minchin, Eddie Izzard, Ian McEwan, Penn Jillette, Adam Savage, Ayaan Hirsi-Ali, Sam Harris, Dan Dennett, Cormac McCarthy, Paul Provenza, Michael Shermer and David Silverman. Presented in the style of traditional rock-n-roll tour films, "The Unbelievers" joins Dawkins and Krauss as they speak to sold-out stadiums and halls across three continents while contending with fans, groupies, critics, debate partners and interviewers, along with religious extremists bent on stifling their pro-science/pro-reason message. Months of international travel culminate at the 2012 Rally For Reason on the U.S. Capitol lawn in Washington, D.C. Billed as the largest gathering of atheists, secularists, freethinkers and skeptics in world-history, Dawkins and Krauss bear witness to the impact of their message as over 30,000 adoring fans and protesters greet them with enthusiasm. Dawkins and Krauss have begun an important conversation about some of the most challenging questions humans have ever faced. "The Unbelievers" seeks to encourage others to continue that conversation. This 2-DVD set includes a Special Features disc with almost 80 minutes of deleted scenes, extended interviews, and a behind-the-scenes featurette."
