Its already been a couple of months since we last saw Game of Thrones on our television screens, as the shows third season culminated with scenes such as the shocking Red Wedding that resulted in Robb Starks death and the freeing of the slaves of Yunkai by Daenerys Targaryen. Season four has already entered development ready for its premiere next spring, though surprisingly little has been revealed thus far in relation to casting, particularly in comparison to last year, where a deluge of new actors and characters were revealed at Comic Con. This is likely because the upcoming season is based on the second half of A Storm Of Swords, the third entry in George R.R. Martins A Song Of Ice And Fire series, and most of the major players from the book have already been introduced. A small number of new cast members have been announced, however, including Pedro Pascal (Oberyn Martell of Dorne), Indira Varma (his paramour Ellaria Sand), Roger Ashton-Griffiths (Mace Tyrell, father of Loras and Margaery) and Mark Gatiss (role TBC). Nothing has been mentioned about the five following characters, however, who will most likely be part of a mass culling of book content (Strong Belwas is amongst the characters already confirmed to not be appearing), something that is unfortunately inevitable due to the difficulty of fitting a story that eclipses 1500 pages into two ten-hour seasons. Not included are characters who could be included to add more depth to the series at this point, but will most likely be added in either seasons five or six given their importance in future storylines, such as Wyman Manderly (who could be used to show The North under Bolton rule) and additional members or bannermen of Houses Greyjoy (such as Victarion and Euron) and Martell (such as Doran, Quentyn, Arianne and perhaps Darkstar). Mild book spoilers will follow, though rest assured there will be no mention of any character deaths or the like.
