Game of Thrones scribe George R.R. Martin has revealed that there are potentially five spinoff Game of Thrones series in development, one more than the originally reported four.
In a blog post, Martin said that the fifth is a recent development. “We had four scripts in development when I arrived in LA last week, but by the time I left we had five,” the author wrote. He said he would wait for HBO to announce the fifth writer once the deal has closed, but called him a “really terrific addition” who knows Westeros inside and out.
