VIDEO : 'The Walking Dead' Season 9 Brings 'Sophistication,' Higher Stakes

The Walking Dead season 9 will bring "sophistication" along with higher stakes, executive producer Scott Gimple tells TV Line. The writer-producer has been with the zombie drama since its second season in 2011, and Gimple, newly appointed Chief Content Officer of the entire Walking Dead brand for AMC, is "enjoying seeing it come together," he adds. With the survivors' war against Negan and the Saviors ended in victory, Rick Grimes and his closest allies are poised for a new world ? but peacetime won't come free of its own challenges. "That leads to very different types of stories and different sorts of conflicts."
