‘Castle’ Creator Andrew Marlowe To Exit As Day-To-Day Showrunner & Focus On Development, David Amann To Succeed HimThere will be a change at the helm of veteran ABC hourlong series Castle. Creator/executive producer Andrew Marlowe will step down as showrunner. He will continue to maintain a day-to-day presence on the show while focusing on developing new projects under his overall deal with Castle producer ABC Studios. Marlowe will be succeeded by Castle executive producer David Amann who will take over primary showrunning responsibility for Season 7. “Over the past four seasons, David has proven himself to be a tremendous leader and a great steward of our show’s unique voice,” Marlowe said. ” I’m excited to continue our creative collaboration as he assumes his new responsibilities, “ Marlowe has run Castle for its six seasons to date. andrewmarloweamannHe was joined by Barry Schindel for the first episodes after the pilot in Season 1 and by another veteran, Rene Echevarria, who co-ran the show with him in Season 2. Under Marlowe’s overall deal with ABC Studios, he developed a Philip Marlowe drama project, inspired by Raymond Chandler’s character. Marlowe’s move resembles that of the creator of another long-running ABC/ABC Studios dramedy, Desperate Housewives‘ Marc Cherry, who stepped down as showrunner after Season 7 to focus on development while continuing on Housewives in a consulting capacity. The series ran for another season, with Cherry returning to write the finale.

Castle, starring Nathan Fillion and Stana Katic, is coming off its most watched season, up 3% in total viewers vs. Season 5, and ranks as ABC’s top drama gainer in DVR vieweing among total viewers. Amann, whose previous credits include Without A Trace, Crossing Jordan and  The X-Files, is repped by Gersh; Marlowe is with CAA.
