Barbara Hershey has joined the cast of “The X-Files.”

According to Deadline, Hershey will play the recurring role of Erika Price, a powerful figure who represents a mysterious organization, in Season 11 of the Fox series. The Oscar-nominated actress joins returning stars David Duchovny (Fox Mulder), Gillian Anderson (Dana Scully), Mitch Pileggi (Walter Skinner), William B. Davis (Cigarette Smoking Man), Annabeth Gish (Monica Reyes), Robbie Amell (Agent Miller) and Lauren Ambrose (Agent Einstein).

Hershey, who recently co-starred on A&E’s “Damien” and has been recurring on ABC’s “Once Upon a Time,” was spotted on the Vancouver set of the Chris Carter-created series on Tuesday.

Fox entertainment chairman David Madden revealed at the Television Critics Association (TCA) summer press tour last week that Mulder and Scully will be looking for their son, William, in the upcoming installment of the sci-fi drama.

“We start the season right up from where the season finale left off with that big helicopter and takes you right from there,” Madden said (via Entertainment Weekly) of where Season 11 picks up. “You’ll be [then] launched into a very urgent adventure that has a lot to do with William — Mulder and Scully’s kid. So the search for William will be a significant thread through the show.”

As to how the 10 episodes of Season 11 will be laid out, Madden confirmed that the new season will be bookended by mythology episodes, and the eight episodes in between will all be stand-alone episodes.

“We’re really proud of last season,” Madden said of the 10th season of the Chris Carter-created series. “We had the responsibility to explain to the audience what had happened in the intervening seven or eight years. We’re free from that responsibility this time and can just plunge in and tell the stories. We’re having a lot of fun doing it. Eight of the episodes will be stand-alone stories so they will be classic ‘Mulder and Scully plunging into new adventures.’”

“The X-Files” Season 11 will premiere midseason on Fox.
