On Thursday the news was handed down that ABC had chosen to cancel Castle, rather than renew it for a final ninth season. It was announced last month that co-star Stana Katic was exiting, but Nathan Fillion had tweeted that he hoped the show would continue for years despite her departure.
"Castle's" cancellation follows rumors of on-set conflict between Fillion and Katic.
"Dear Castle fans, cast and crew", her letter began. The network is reimagining the film Training Day and the series MacGyver, while also slotting Joel McHale into the lead in comedy The Great Indoors and Matt LeBlanc in Man With a Plan.
"To the whole Castle family- our unbelievable cast, our remarkable crew, our imaginative writers & our wonderful fans, thank you for 8 fantastic yrs!" show creator Andrew W. Marlowe tweeted on May 12.
The series finale of Castle airs Monday at 10 p.m ET.
"Agent Carter" star Hayley Atwell already has her next series lined up: She'll be starring in ABC's "Conviction", as a troubled lawyer from a political dynasty.
There were rumors that the network was looking to renew the show for an abridged ninth season, but ABC ultimately made a decision to cancel "Castle". While the ratings were never really high, they weren't anything bad, averaging at 6.52 million views during the first season. Even though "Castle" is titled as such, the TV series has been mostly about Rick and his wife Kate Beckett (Stana Katic).
Numerous show's stars have taken to Twitter and Instagram to voice their feelings on the cancellation and thank the fans for their continued support. "They will not speak when they are off set, and this has been going on for seasons now". In this Tweet, he says that in whatever project he ends up working on next he wants them all to notice just how different from Castle it is.
