With Under The Dome last year and Extant this week, CBS has made the addition of a new thriller event drama series the highlight of its summer schedule. The network has locked in its high-profile drama entry for summer 2015 with a 13-episode straight-to-series order to Zoo, a drama based on James Patterson‘s best-selling global thriller. The project, which had a rare pilot production commitment for a pitch originating from sibling CBS TV Studios, hails from writer-producers Josh Appelbaum & Andre Nemec, Jeff Pinkner and Scott Rosenberg. The four are working under their new Midnight Radio moniker (formerly Space Floor) which has inked a two-year first-look deal with CBS Studios. Also producing are Cathy Konrad and James Mangold via their CBS Studios-based Treeline Films, with Mangold set to direct.
