The showrunners of FX's Y: The Last Man (which has been shortened to just "Y") have announced their exit from the series over disagreement with the network. Aida Mashaka Croal broke the news on her own Twitter, in a letter co-signed with co-showrunner Michael Green.
"Sad news for fans of Y: The Last Man today. FX has decided not to move forward with our series in its current form," Croal tweeted. "We are grateful for everyone who came together to make our pilot and build the world of Y ... Our writing staff, director Melina Matsoukas, DP Rodrigo Prieto, and cast including Lashana Lynch, Barry Keoghan, Diane Lane, Imogen Poots, Amber Tamblyn, Julianna Canfield ... And of course, the minds who started it all, Brian K. Vaughan and Pia Guerra."
"We hoped to reward their talent and their trust not just with success but with a show that had something to say, in a time when things must be said," Croal continued. "As Y fans ourselves, we hope the future allows just that."
FX ordered a Y pilot in April 2018, with production beginning in August. While it hasn't been confirmed if the pilot was completed, the network ordered a full first season of the show in February of 2019.
FX is reportedly moving forward with the series (and the cast), and is now seeking replacement showrunner(s) according to Deadline.
