Creator Andrew Marlowe, who has run the Nathan Fillion-Stana Katic series since 2009, will still have a presence on the ABC procedural.

Things are going to look a little different at the top of the Castle ranks.

Creator Andrew Marlowe, who has served as showrunner since the ABC procedural's first season, will hand over primary duties and responsibilities to executive producer David Amann for season seven, The Hollywood Reporter has learned.

In doing so, Marlowe will still maintain a day-to-day presence on Castle, as well as continue developing new projects as part of his overall deal at ABC Studios.

“Over the past four seasons, David has proven himself to be a tremendous leader and a great steward of our show’s unique voice. I’m excited to continue our creative collaboration as he assumes his new responsibilities,“ said Marlowe.

Amann first joined the Nathan Fillion and Stana Katic drama in 2010 during the series' third season, and has written nearly a dozen episodes. His other producing credits include lengthy stints on The X-Files, Crossing Jordan, Without a Trace and Three Rivers.

Heading into its seventh season, Castle continues to be a strong ratings performer for ABC. Season six saw Castle improve 3 percent over season five in total viewers, delivering its most-watched season to date.

Amann is repped by Gersh. Marlowe is repped by CAA.
