Yeah, it's pretty much impossible to speculate on cast. The effects, costumes, sets, etc. will be straining the budget something fierce. If "Rome" had budget problems, this series' budget could be off the charts.

I guess they could use CGI a ton, but, unlike, "Rome", most of which took place in, well, Rome, there are just so many different locations that are so varied in look and feel. You have Winterfell, Kings Landing, the Wall, all that stuff out East with Dany and those are just the "main" locations in the books. (Beyond that is Dorne, Harenhal, The Aerie, Riverrun, The Twins, etc, etc.). It would be sweet to see those locations come to life, but I don't know how they will do it well and in a cost-effective manner.

HBO always seems to do a decent job of getting relatively unknown, yet extremely talented, actors for its shows. I really wasn't familiar with much of anyone (other than a few exceptions) who starred in "The Wire", "Rome", or "Deadwood" and they all had very solid casts. I would imagine that this series would be cast in a similar vein.

The only two "big name" actors I can think of off the top of my head that would be perfect would be Liam Neeson for Ned Stark (there's really no one of note who'd fit better for that role) and Peter Dinklage as Tyrion.

I always pictured Bryden Tully looking almost exactly like Sam Elliot, but he's a pretty minor character and I certainly wouldn't expect that casting. He's just one of the few characters in the books I had always matched up with an actor.

One problem they will encounter will be the fact that a lot of the main characters in these books are children. Children are notoriously hard to cast not only because there are so few good child actors, but because they age between seasons (see, e.g., Walt from "Lost"). I think they will just have to bite the bullet and make all of the kids a bit older and cast actors who appear younger than they are.
