“The audience-driven success of ‘The Walking Dead’ and ‘Talking Dead’ (even before time-shifting) is remarkable, and something we never take for granted,” said Charlie Collier, AMC president. “We hold in such high regard Robert Kirkman, Scott Gimple and all of our exceptional executive producers, cast and crew for their passionate efforts that led to television history for ‘The Walking Dead’ once again last night. Congratulations and ‘non-creepy hugs’ to Chris Hardwick and everyone associated with making ‘Talking Dead’ not only the #1 talk show on television, but one of the top 18-49 shows in all of television, period. Huge thanks to all of our great partners and, of course, to the fans who make it possible.”
