“There will be some iconic characters but mostly this is about a new family,” Walden said. “It’s about an average family who encounters this extraordinary world and children who have mutant powers and they end up on the run, so it’s a little bit underground railroad in terms of a storytelling spine.” 

“We did see an early draft of Hellfire and there was a lot of work to be done,” Walden said. “Manny and Evan were getting very busy with the new 24. At a certain point we all regrouped, together with Simon Kinberg and Bryan Singer and Lauren Shuler Donner and Jeph Loeb at Marvel and really made a decision. I would say if there was anything about Hellfire that was not ideal for us, it felt like a show that wanted to live as a feature rather than really taking advantage of what television does best: exploring relationships and characters and smaller moments. It doesn’t mean it can’t feel like a big show but Hellfire felt more like another installment of the features.”

Fox-owned cable network FX has an X-Men series ready to air. Legion stars Dan Stevens, from Fargo creator Noah Hawley, and will air in early 2017.
