Natalie Dormer is headed to the "City of Angels."

The "Game of Thrones" alum is set to star in a lead role on Showtime's upcoming "Penny Dreadful" revival.

"Penny Dreadful: City of Angels," described as a spiritual descendent of the original series, features all new characters and storylines. The show is set in 1938 Los Angeles, a time of deep social and political tension.

When a grisly murder shocks L.A., Detective Tiago Vega (Daniel Zovatto) is embroiled in an epic story that reflects the rich history of the city: from the building of the 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.

Dormer will play Magda, a supernatural demon who can take the appearance of anyone she chooses and who manifests in a number of guises throughout the story. Described as charismatic, clever and chameleon-like, she is a dangerous enemy and invaluable ally.

The project marks a return to Showtime for Dormer, who previously played Anne Boleyn in "The Tudors." She may best known as Margaery Tyrell in "Game of Thrones" and also appeared in "The Hunger Games: Mockingjay."
