Game Of Thrones Season 4 Cast Update: Styr, Magnar Of Thenn Cast, Tommen Baratheon Re-Cast, And Natalie Dormer Join The Hunger Games

As "Game of Thrones" season 4 continues production and filming, several cast members will join the HBO series, while others land new acting gigs.

For season 4, "Game of Thrones" has cast Joseph Gatt ("Thor") in the role of Styr, Magnar of Thenn. The Wildling will join the already massive cast soon, along with newcomer Mark Gatiss and Pedro Pascal.

Meanwhile, "Game of Thrones" season 4 will also re-cast one character: Tommen Baratheon.

Joffrey's little brother may not have had a big role in the series so far, but actor Callum Wharry will reportedly not be returning for season 4 after portraying the character in season 1 and 2 of "Game of Thrones."

According to Hypable, actor Dean-Charles Chapman, who played a young squire captured by Robb Stark that was killed by the Karstarks in season 3.

Reportedly, this is an attempt to age the character appropriately, an issue that will plague a lot of the young cast members potentially in the future.

But out of "Game of Thrones," a slew of cast members from the hit HBO series will be gracing the big screen, no doubt thanks to the exposure of "Game of Thrones."

Natalie Dormer has been cast as Cressida for "The Hunger Games: Mockingjay," while Kit Harington can be seen in the brand new trailer for "Pompeii," according to Time Magazine.

Peter Dinklage, famous for playing Tyrion Lannister in "Game of Thrones," will play Bolivar Trask in "X-Men: Days of Future Past."
