A day after getting an eighth season pickup, ABC drama Castle has enlisted a new showrunner. Series writer Terence Paul Winter will succeed David Amann, who recently stepped down. We now have a renewal, showrunner and male lead, Nathan Fillion, secured for next season. Still up in the air is the return of co-star Stana Katic, who has not yet reached an agreement for a new contract.

Winter is repped by CAA, Sheree Guitar Entertainment and attorneys Linda Lichter and Jonathan Shikora at Lichter Grossman Nichols Adler & Feldman.
