^^^I'd actually watch HBO again for that. Hmm, Pruitt Taylor Vince for Abner? In the end of course, anybody sufficiently glamorous and sexy can play Joshua.
But on the subject of G.R.R. Martin, what really would be mindblowing would be a film version of Armageddon Rag. Although I suppose it would take a screenwriting team of Tony Kushner and Stephen King to do it justice.
