from hollywoodreporter.com: The Walking Dead may have dominated the dial on Sunday night, but it did not stop HBO from setting a handsome record with its latest documentary premiere. Going Clear: Scientology and the Prison of Belief, Alex Gibney’s two-hour exposé on the Church of Scientology, nabbed nearly 1.7 million viewers during its premiere telecast. And while that number is sure to grow once HBO-Go plays, encores and DVR views are taken into account, it already represents the network’s most watched doc premiere since Spike Lee’s four-part When the Levees Broke aired in 2006.
