In terms of long-gestating, it doesn’t get much more long-gestating than the live-action adaptation of Brian K. Vaughan and Pia Guerra’s Y: The Last Man that’s been spinning its wheels in development hell for years.

After an age being planned as a movie or more recently as a TV series, all looked well as FX was moving ahead with a TV take on the iconic comic book property. But now, in another twist for the adaptation, star Barry Keoghan has departed the FX show.

Via Collider, Dunkirk actor Keoghan has exited as Y’s titular Yorick Brown. No reason has been given for Keoghan’s departure, although it’s yet another bump in the road for the series. Scenes had actually already been shot with Keoghan as Yorick, meaning that reshoots will obviously have to take place once the show finds a new Yorick.

As alluded to, this is just the latest setback for Y, with showrunners Aida Mashaki Croal and Michael Green having both left the series previously. At the last count, Eliza Clark was on board to serve as showrunner.

Y: The Last Man centres on Yorick Brown as the sole human male survivor after the planet has been hit by a strange event that killed off all mammals with a Y chromosome.

The previous plan was for FX’s Y to premiere before 2020 was out, although it now looks like the series won’t hit TV screens until at least next year.
