As "Game of Thrones" season 4 continues filming, the trend of new cast members is growing by the week, this time with Jane McGrath and Icelandic music sensation Sigur Ros joining the series!

According to an interview with Irish Film & Television Network, Jane McGrath revealed that she will be portraying a Wildling woman in "Game of Thrones" season 4, although her exact role remains top secret.

"I'm not even allowed to talk to my friends about it and can't be giving anything away! My character is beyond the Wall and it was stunning. When you're on set you feel like you're actually there. It's incredible!" says McGrath on her filming experience on "Game of Thrones."

The Irish actress does not have an extended or well-known resume, but landing a "Game of Thrones" cast gig should surely boost her career, as it has with all of the cast members in some respect.

Meanwhile, the Icelandic indie band Sigur Ros will be making a cameo during "Game of Thrones" season 4.

According to EW, Sigur Ros members Jón Þór "Jónsi" Birgisson, Georg Hólm and Orri Páll Dýrason are currently shooting their appearance in Croatia.

Reportedly, "Game of Thrones" executive producers David Benioff and Dan Weiss often listen to the band for inspiration while shooting in Iceland for the series.

Also joining the "Game of Thrones" season 4 cast are Michiel Huisman, Mark Gatiss, Joseph Gatt as Styr, Indira Varma as Ellaria Sand, Haftthor Bjornsson as Gregor Clegane, and Pedro Pascal.
