Fox’s upcoming comedy Son of Zorne is having a hard time keeping its creators and showrunners.

Eli Jorne, who co-created the project with Reed Agnew, has exited the show due to creative differences. Agnew and Jorne were also slated to be the showrunners for the series, just as they were for their previous project, Wilfred. Jorne’s departure means that now neither creator will serve as the showrunner for Son of Zorn since Agnew too had stepped down from his position as showrunner.

Sally McKenna, who stepped up to be a co-showrunner with Jorne when Agnew stepped down, will now be the sole showrunner for the series. Agnew will still be an executive producer for the series along with McKenna, Chris Miller, Phil Lord, Seth Cohen, and Eric Appel. Jorne, however, is no longer involved at all in Son of Zorn.

The project received a straight-to-series order from Fox for the 2016-17 season, and Variety reports Jorne’s departure will not affect the series.

Son of Zorn is a live-action and animation hybrid series about Zorn (voiced by Jason Sudeikis) who ends up on Earth after being gone for 10 years. Zorn is an animated and legendary warrior, like something from a 1980’s cartoon. On Earth, Zorne tries to reconnect with his son, Alan (Johnny Pemberton), and ex-wife, Edie (Cheryl Hines). Although a war is waging in Zorn’s homeland (or planet?) of Zephyria, he tries to balance a boring job and suburban life. Of the details that have been released about the series, it looks like Zorn is the only character who will be animated and not live-action.

Tim Meadows (Saturday Night Live) has also been cast in Son of Zorn.

Son of Zorn will premiere this fall on Fox.
