Game of Thrones Season 4 Spoilers are heating up, as it looks like casting may already be underway. An audition tape leaked online recently. The Dutch actor Yorick van Wageningen seems to be auditioning for Styr, the Magnar of Thenn. Readers of the books will note he looks very little like book-Styr, perhaps he the role will be a combination of book characters. Part of Styr's role has been taken up by Tormund this season. Some think he may take Rattleshirt's parts from the book since we have not seen him this year and he has future parts to play in the books.

The scene appears to be between Styr and Tormund (and possibly Ygritte) and would be some time after this season ends. Meaning no attack on Castle Black in Season 3. In the past audition scenes did not necessarily make the TV series though, so no guarantee it will play out this way on screen.

GRRM was recently interviewed at ConQuest in Kansas City and gave us some hints about casting with this tweet:

"Auditions are being held now for season 4 - including Styr the Magnar of Thenn, Mace Tyrell and OBERYN MARTELL!"

Also of possible note, there are rumors of Ellaria Sand also being cast sometime soon. No official source on that yet and at this point it is complete rumor, but combine that with Overyn and Mace being cast and it looks like D&D are not cutting large sections of the books to complete the series fast as some suspected.
