Natalie Dormer, who plays Margaery Tyrell on "Game of Thrones," teased that the power play in King's Landing will be a lot more complicated when the show returns for its fifth season next year.

"It's definitely gone in a new direction, without giving anything away to people who don't know the books and don't want spoilers," the 32-year-old British actress told Access Hollywood at People's Ones To Watch party at The Line Hotel in Los Angeles Thursday night, Oct. 9.

 "There's a kind of coup that happens within the capitol," she revealed. "So [that is] one more dynamic to the ever-turning madness that is the power play of 'Game of Thrones.'"

And even though there is an increasing tension between her character and Lena Headey's Cersei Lannister, Dormer said that she and Headey are actually close friends off-camera.

"I love Lena so much and we have so much fun where we're being really horrible to each other and as soon as the camera turns off, we just have to stop ourselves bursting out laughing a lot of the time," she shared.

Meanwhile, Dormer was named one of People's Ones To Watch Thursday, and she said that she is blessed to be part of three ongoing franchises:  "Game of Thrones," "The Hunger Games" and CBS' crime drama series "Elementary."

"I'm very lucky with all the projects I'm in that the fan base is so amazingly dedicated and strong," she said. "The fandoms of 'Game of Thrones,' 'Hunger Games' [and] 'Elementary' alone -- those three projects, I'm just -- I'm blessed. I totally am, and to do these other great movies that I do as well, to add to that equation -- I'm grateful."

"It's a beautiful moment at the moment," she added. "I'm aiming for the horizon. Got my head down, trying to work hard and sleep."

Dormer appeared in the final three episodes of the first season of the "Elementary" as Irene Adler/Moriarty. She also reprised the role in an episode in the following season.  And in the show's New York Comic Con panel just this weekend, producer John Polson said that they are always looking to bring Dormer back, Hypable reported.

In August 2013, it was announced that Dormer was cast as Cressida in "The Hunger Games: Mockingjay - Part 1" and "Part 2," and in preparation for the role, she shaved the left side of her head.

"It's fascinating how much of our sense of attractiveness and feminine identity is bound up in our hair," Dormer told Glamour in May. "But in the Mockingjay novel, Cressida is described as having a shaved head with a vine tattoo, and I wanted to do right by the book."

"Cutting one side of your head for a few months is not a big deal compared with what other people have to deal with in the world. Plus, hair grows back," she explained. It just takes time getting used to."
