Over at “Not a Blog”, George R.R. Martin has added a couple of comments in reply to fan queries about HBO’s adaption of his work.
First, in response to a question about the change of Robert Arryn’s name to Robin Arryn, he writes about how he deliberately broke traditional convention by having characters with similar or even the same names, and cites the historical fact that in Europe many of the noble families would simply reuse the same few names (he specifically notes all the Edwards and Henrys in England, and how heirs named Arthur or Eustace never managed to survive).
Then in another response to a remark about how much involvement he has in the production compared to other authors who sell the adaption rights to their works, George cites that his previous Hollywood experience certainly proves helpful in his being involved in a meaningful basis. On top of that, he notes that many SF/F authors don’t make much money from their books, so are just happy to have someone interested in the rights and willing to cut a check. His personal preference, however, is to meet the would-be producers and see what they have to say, rather than just accepting an offer without deliberation.
