The residents of Westeros seem to be flocking to Panem as two "Game of Thrones" stars join the cast of "The Hunger Games: Mockingjay — Part 2," the second half of the movie adaptation of Suzanne Collins' final book in "The Hunger Games" trilogy.

In the first part of "Mockingjay," actress Natalie Dormer was first introduced as Cressida. She was the resident director at the Capitol before joining the rebellion and moving to District 13 to put an end to the tyrant leadership of President Snow (Donald Sutherland). 

Dormer had to perform difficult physical tasks for the film, particularly running while carrying a heavy firearm. This is very far from her very poised and regal character in the TV adaptation of George R.R. Martin's novels as Margaery Tyrell. 

The actress talked about how she managed to keep in shape for her role in the film in the April issue of Self magazine. 

"In 'Mockingjay - Part 2,' I'm basically running around in heavy armor while carrying a semiautomatic rifle," the British actress shared during the interview. "I don't know how I would have kept up with [my costars] Liam Hemsworth or Sam Claflin if I hadn't been in the best cardiovascular shape of my life." 

The actress also mentioned that she had to run in the streets of Atlanta in the morning then squeeze in a one-hour interval workout at night, while filming for the movie for at least 12 hours a day. She even found time to train for the London marathon while doing it. 

Aside from Dormer, Gwendoline Christie, the actress who portrays the role of Brienne of Tarth, joins the "Mockingjay — Part 2" cast as former District 2 victor-turned-rebel leader Commander Lyme. She helps Katniss Everdeen (Jennifer Lawrence) and the rest of the rebels infiltrate the Capitol. Her role in both the "Game of Thrones" and "The Hunger Games" are somewhat similar since both require combat stunts. 

"The Hunger Games: Mockingjay — Part 2" is slated for a worldwide premiere on Nov. 20.
