We still don’t know what to actually call FOX’s Bryan Singer-directed X-Men drama, but fresh off the success of Legion, our new series is already casting. Blair Redford has joined in the role of our first notable mutant, potentially providing a clue to the plot.

Entertainment Weekly revealed that Switched at Birth star Redford would take the role of Sam, described as “the strong-headed Native American leader of the underground network.” It’s possible the name is a cover, while it remains unclear if said “underground network” is intended to reference a more famous group of outcast mutants.

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), though Nix previously doubted any major interaction:

I guess I’d say in a sort of general way it acknowledges that events like the events that have happened in the movies have happened, you know what I mean? But it’s not to date… it’s still evolving. We’ll see how much that comes in. It’s certainly not “Since this happened in X-Men Apocalypse now all of these things are happening!”, which I think is cool, but they already did that. […]

It yet isn’t clear if FOX will issue a series order, but who might the first cast member represent?
