We’re not even going to harp on a missing title for FOX’s Bryan Singer-directed X-Men drama, thanks to the latest addition. Multiple Whedon-verse alum Amy Acker has been set as the series’ second major lead, along with several new castings that include recognizable mutants.

Per The Hollywood Reporter, Acker will star as second parent Kate Stewart, a woman struggling with her separation from her husband Reed (True Blood alum Stephen Moyer) and her increasingly challenging teenage children. Worth noting, the series also recently cast another Gotham alum in the form of Natalie Alyn Lind as Kate’s teenage daughter.

Also cast is Bunheads alum Emma Dumont as Lorna Dane/Polaris, a metal-manipulating mutant typically portrayed as one of Magneto’s lesser-known children. Other recent additions include Sean Teale as Eclipse, Jamie Chung as Marvel mutant Blink (who Singer had previously showcased in Days of Future Past) and Switched at Birth star Blair Redford as a Native American mutant leader.

FOX had previously set franchise helmer Singer to direct a pilot for the untitled new drama from Burn Notice creator Matt Nix, said to follow “two human parents who discover their children as mutants, forcing them to run from a hostile government, and join with an underground network of mutants to survive.” The series was also said to take place in the universe of the films, potentially including Sentinels as well.

We don’t yet know if FOX will issue a series order (or even a gosh-darn title), but who else might join the cast?
