There is a second behind-the-scenes change at Fox’s hybrid live-action/animated comedy series Son Of Zorn, from Last Man On Earth executive producers Phil Lord & Chris Miller and former Wilfred showrunners Reed Agnew and Eli Jorne.

Jorne, who co-created the project with Agnew and had served as co-showrunner, is departing the series over creative differences, leaving Sally McKenna as the sole showrunner at the moment. Production on the series won’t be affected by the change. Son Of Zorn is currently about half-way through its 13-episode order.

McKenna was brought in when Agnew, originally slated to co-showrun with Jorne, stepped down as co-showrunner but remained on the show as exec producer. McKenna and Agnew exec produce with Phil Lord, Chris Miller, Seth Cohen and Eric Appel.

Son Of Zorn employs a mix of live-action and animated lead characters. Upon arriving home on Earth for the first time in 10 years, Zorn (Jason Sudeikis), a fully animated, legendary warrior, finds that reconnecting with his live-action son, Alan (Johnny Pemberton), and ex-wife, Edie (Cheryl Hines), while suffering through a mundane office job and the banality of suburban life, is harder than waging actual war in his distant, mystical homeland of Zephyria. Tim Meadows also stars.

Son Of Zorn is produced by 20th Century Fox Television where Miller and Lord are based.
