That would be a great idea to cut costs. I'm all for it, so long as the information gets out. They could even stylize it enough so as to have the still appear to be various works of art, like, say ... figures in a stained glass window for one, or carved in stone on another, or illustrated with Ye Olde Faency lettering in a thick book.

Huh. Looks like our Drogo is getting popular.

Jason Momoa cast as Conan...?

This article says it too.

No idea if that changes anything for GoT. Perhaps (like Ehle with her theater schedule) they are working around it.

Conan's pretty big though.

There we go.

Anyway.

Looking good, Winter!

As to the weirwoods ... I think they will look more than a little creepy. The initial reaction could be akin to What the Hell is THAT? to anyone uninitiated in ASoIaF.

Thinking about it, the first few scenes in the pilot episode will all have moments of WTF:

Prologue: the Others eat Jamie Campbell-Bower.
Next we see Castle Black at THE WALL - gigantic edifice of ice.
Over to Bran, watching calmly as his father serves up the King's Justice.
Transition to monstrous dead wolf.
Over to Ned and Catelyn under the creepy, red-leafed weirwood.

Think about it. The most normal scene is where the kid watches a dude get beheaded.

Heh. Gonna be so good...
