What other books have they botched on the telly? Or are you referring to movies and stuff?
If you like Martin, you may want to check out R Scott Bakker and Stephen Erikson. I believe Martin has given at least one of em positive reviews, and I know both have a healthy respect for him as well. All three take the worldbuilder fantasy approach...but, in a nutshell, Martin draws on history, politics, and war, Erikson draws on archeology, anthropology and war, and Bakker draws on philosophy, religion, and war (alright, they all use war). Well, they all work off these themes at times, but I would say these are their stronger points. I don't really want to go into story, though that'd be the only real way to convince you, so I'll leave it at that and let you look if you run out of reading and want more.
I actually started with Erikson's second book,
Deadhouse Gates, which may have been a good decision; a lot of people drop Erikson in his first novel because it is quite simply his weakest (he wrote it in something like 1992, and I believe the 2nd was written in 98). It also doesn't hurt continuity too much, because there's little relation between the first and second book (#1's continues in #3, #2 in #4, and then they both meet together in #6 while #5 starts a new story XD). If it counts, he wrote the book off of DND stuff a la Salvatore.
They seem to be compared a lot online (well, Bakker not so much, he hasn't really boomed much yet), but I have to say I don't have a sure favorite. They really have their own strengths and weaknesses. Bakker stands out a little from the other two, but only because he has a main character who so far has been insanely able and perfect. The only thing both Erikson and Bakker definitely have over Martin is an ability to create closure at the end of each book...but that's not really a crippling weakness for Martin.
I just digressed quite a lot.
Someone at the forum I found out about this posted up a
fanmade casting site for the TV series. Just for fun.
I was reading something random on the Eragon movie recently, and I feel like Jeremy Irons might make a good Stannis facially. I can't remember whether Irons has grey or brown hair, but if he just shaved some off and dyed it he'd prolly be good. But I don't really know actors in general. The only show I've watched recently is
The Wire, and something like 60% of its cast is black, which doesn't mesh well with most of Martin's characters.
