AMC didn’t hold an executive Q&E session at TCA, just a panel for upcoming drama The Killing. But at the beginning of that panel, the network’s executives addressed the big question: the future of the network’s flagship series Mad Men. There is no deal yet with Lionsgate TV for a fifth season of the Emmy-winning period drama or between Lionsgate and series creator Matthew Weiner for him to continue on the show. Just like two years ago, both are proving to be nail-biters, with a lot of money on the line. The plan is to bring Mad Men back for Season 5, AMC SVP Joel Stillerman told reporters before introducing The Killing panel but was quick to note that he didn’t know when. After the panel, our contributor Ray Richmond asked AMC president and GM Charlie Collier about the state of the Mad Men renewal. “We’re negotiating, don’t know much more than that yet,” he said. “Can’t put a timetable on if.” Last time around, the deals closed in January, shortly after Mad Men had triumphed at the Golden Globes.
