The axe has been swinging in the US ahead of the Upfronts season.
Castle has been axed after 8 seasons.
The news comes after word Stana Katic would not be returning, and despite Nathan Fillion signing in the hope of more.
The Hollywood Reporter notes the cancellation came after talks about a final abbreviated season and as ABC faced a more immediate deadline to make the decision as producers were up against the wall and tasked with editing the season finale. Producers filmed two different endings as the drama hung in the balance and had prepared both of what would be a series finale and a season finale that left the door open for another cycle. It ends in the US next week.
No surprises that the revived Muppets series is also a goner. The show was never well-received by the critics, or audiences. A missed opportunity.
Seven also loses out with musical fantasy, Galavant ending with two seasons. Star Joshua Sasse has signed on to star in The CW pilot No Tomorrow. It continues to air on 7flix.
Meanwhile the news is worse for TEN with CSI: Cyber axed, plus new series The Grinder and Grandfathered. TEN has been planning to debut the latter two on its primary channel, but may need to rethink that or move them to summer.
Despite stars Rob Lowe and John Stamos, respectively, The Grinder averaged 3.4 million US viewers while Grandfathered had 4 million in live-plus-seven day viewing.
