Fox has officially ordered a pilot for its untitled X-Men series. According to Variety, the new series will involve Burn Notice creator Matt Nix as showrunner, and X-Men series director Bryan Singer is on board as executive producer.

Word that 20th Century Fox was developing a series in the X-Men universe first got out last summer, and little has changed about what we know about the series since then. The show will reportedly follow a couple who discover that their children are mutants and must go underground to keep them safe. Fox is working with Marvel Studios on the effort, and the show is expected to exist within the X-Men movie universe.

This is only the second show Fox is working on that tells X-Men stories on the small screen. Legion, which is set to premiere next month on FX, also focuses on mutants and their world, but exists in a separate universe. “With the X-Men comics, there are a lot of alt universes, so that has allowed me some leeway,” showrunner Noah Hawley told Variety. However, depending on that show’s success, there’s a real chance of a crossover at some point in the future. “I have to prove that the show is good enough to incorporate those elements from the movie world, if that were ever possible,” he said.
