X-Men based HELLFIRE TV show on the search for new showrunners.

Fox television chairman Dana Walden confirmed to Deadline that their developing X-Men tie-in HELLFIRE is searching for new showrunners after Evan Katz and Manny Coto exited to focus on the upcoming “24: Legacy” pilot.

A script by “Star Trek Beyond” scribes Patrick McKay and JD Payne was written for the show, which is set in the late 1960’s and follows a young Special Agent who learns that a power-hungry woman with extraordinary abilities is working with a clandestine society of millionaires – known as “The Hellfire Club” – to take over the world.

X-Men film producers Lauren Shuler Donner, Bryan Singer and Simon Kinberg will executive produce along with Marvel TV’s Jeph Loeb and Jim Chory.

“We are thrilled to partner with Marvel to bring this world to television and build upon the Fox Logo vibrant mythology that has captivated fans for years,” said Fox Entertainment president David Madden last October. “These powerful and dynamic characters are complicated and larger-than-life, the pace and visual imagination are unrelenting, and the story takes place during one of the most explosive eras in recent history.”

Kinberg previously stated that the hope was to film the pilot early this year. Whether that happens or not will depend on if they can find a new showrunner in a timely manner. According to Walden, it’s “unlikely” the show will debut by this Fall. “Potentially midseason,” she says, “but no immediate plans. We’re still working on Hellfire Club. Obviously those executive producers are very busy with the film franchise and the FX show [LEGION], so not sure.”
