“Lillah is one of the most successful development and programming executives in our industry,” said Shearmur. “She has great taste, experience and a phenomenal touch with the material she champions, and she is respected and admired by talent, programming executives, agents and writers. I have known Lillah for many years and am thrilled and excited to partner with her as we expand our footprint in television.”

Prior to her years at TBS and TNT, McCarthy was the executive producer of the CBS series Early Edition. Before producing, McCarthy held executive positions at two networks: ABC, as a current executive, and at Fox, as SVP Series Programming.
