The first season of “Penny Dreadful: City of Angels” is adding an extra smirk-full of Natalie Dormer (Game of Thrones). The network announced today that Dormer has joined the first season of the spinoff series, which is the next chapter in the Penny Dreadful story. Dormer is taking on the role of Magda, a supernatural demon who can take the appearance of anyone she chooses, and will manifest in a number of guises throughout the story.

The network describes the character saying that she is “charismatic, clever and chameleonic, Magda is a dangerous enemy and an invaluable ally.”

Tony and Golden Globe award winner and three-time Oscar nominee John Logan, creator, writer and executive producer of the Emmy nominated series “Penny Dreadful,” will continue in those same roles. Michael Aguilar (KIDDING) will also serve as executive producer. Production on the drama series is expected to begin later this year.

Most fans were introduced to Dormer as the would-be queen Margaery Tyrell for the first six seasons of Game Of Thrones. Dormer’s previous television credits include her starring role as Anne Boleyn on the hit Showtime drama “The Tudors,” along with “Picnic At Hanging Rock,” “The Scandalous Lady Woman,” and “Elementary.”

Dormer’s film credits include “In Darkness,” which she co-wrote with the film’s director Anthony Bryne. Previous film credits include the lead role in the supernatural thriller “The Forest,” “The Hunger Games: Mockingjay Parts 1 & 2,” “The Riot Club,” “Rush,” “The Counselor,” “W.E” and “Marvel’s Captain America: The First Avenger.” Fans of the actor will also get to see her in “The Professor and the Madman,” and “The Dark Crystal.”

As for the series, “Penny Dreadful: City of Angels” opens in 1938 Los Angeles, a time and place deeply infused with social and political tension. When a grisly murder shocks the city, Detective Tiago Vega (Daniel Zovatto) is embroiled in an epic story that reflects the rich history of Los Angeles: from the building of the city’s first freeways and its deep traditions of Mexican-American folklore, to the dangerous espionage actions of the Third Reich and the rise of radio evangelism.

Before long, Tiago and his family are grappling with powerful forces that threaten to tear them apart. The series will also star Jessica Garza (The Purge) and Johnathan Nieves (New Amsterdam).
