re: GoT Season 7 Casting News, Speculation, Spoilers, etc.

Based upon the casting descriptions we saw last August-September (summarized here) for roles that ended up being Euron Greyjoy, Khal Moro & his bloodriders, Smalljon Umber, young Ned Stark & young Hodor (amongst others), we should get some similar clues in the next few weeks & months. I don't expect there will be many cast additions this season at all (Dan said something to the effect of "We are really just trying to work with the pieces we already have"). The only major figure - and it may not be a role with much screen time - would be Rhaegar. I'll be interested to see if they cast a notable or semi-notable actor for the role (along the lines of Ian McShane's one-episode run) or go with a relative unknown (Tower of Joy actors).
