With this week's third-season premiere of HBO's Game of Thrones, enthusiasm for the Lannisters and Starks and Baratheons and all the others is at a fever pitch. With the show in such high demand, so is its cast, and a good many GoT cast members will be showing up in 2013 movies as a result. Here's a quick guide.

Peter Dinklage
The Emmy-winning actor behind Tyrion Lannister is going to have a busy year ahead of him, and that's before he joins the mutants onscreen for X-Men: Days of Future Past. He'll join Mila Kunis, Robin Williams, and Melissa Leo for The Angriest Man in Brooklyn, about a man on the last day of his life.

Lena Headey
As power broker Cersei Lannister, Headey is no stranger to medieval struggle, which should mean she'll slip quite easily back into her role as Gerard Butler's wife in 300: Rise of an Empire. She'll also co-star with Ethan Hawke in the futuristic thriller The Purge. Due in theaters at the end of May, Purge boasts perhaps the greatest plot synopsis of all:

Given the country's overcrowded prisons, the U.S. government begins to allow 12-hour periods of time in which all illegal activity is legal. During one of these free-for-alls, a family must protect themselves from a home invasion.

Emilia Clarke
The actress behind exiled dragon-monger Daenerys Targaryen recently finished a stint on Broadway as Holly Golightly in Breakfast at Tiffany's. Later this year, however, she'll join Jude Law for the crime dramady Dom Hemmingway.

Kit Harington
While Jon Snow cools his heels north of the Wall, Harington is gearing up for his first major leading role on the big screen, in Paul W.S. Anderson's Pompeii. That's not due out until 2014, though. In the meantime, he'll appear in the 18th-century fantasy adventure The Seventh Son, alongside Jeff Bridges, Julianne Moore, and Ben Barnes.

Natalie Dormer
If Margaery Tyrell isn't your absolute favorite Game of Thrones character, you're not paying attention. Natalie Dormer's career is getting quite the springboard these days. She's in the upcoming Ron Howard auto-racing film Rush, alongside Daniel Bruhl, Chris Hemsworth, and Olivia Wild. She's also in the Cormac McCarthy-scripted, Ridley Scott-directed The Counselor, playing "The Blond" alongside an all-star cast including Michael Fassbender, Brad Pitt, Javier Bardem, Cameron Diaz, and Penelope Cruz. Both films hit American screens in the fall, with Rush premiering in September and The Counselor on November 15th.

Carice Van Houten
November 15th will be quite the test of loyalties for GoT fans, as both Dormer and Van Houten are debuting major films. That's when the actress behind red-haired enchantress Melisandre will return to the very contemporary realm for The Fifth Estate, director Bill Condon's film about WikiLeaks and Julian Assange.

Nikolaj Coster-Waldau
You won't have to wait quite as long to see Kingslayer Jamie Lannister on your movie screen. After joining Jessica Chastain this past winter for Mama, he will co-star in the Tom Cruise blockbuster Oblivion, in theaters this month.

Ciaran Hinds
Having just debuted as the King Beyond the Wall, Mance Rayder, on Game of Thrones, Hinds will be on movie screens in both halves of the The Disappearance of Eleanor Rigby movies, with Jessica Chastain and James McAvoy. He will also be in the international legal thriller Closed Circuit, alongside Eric Bana and Rebecca Hall.
