A fifth writer, and show pitch, was added after the initial announcement
Bryan Cogman, the writer behind many first-run Thrones episodes, has stepped up to develop a fifth idea, reports Entertainment Weekly.
Martin is heavily involved with the world-building
"I've actually been working with all four [now five] of the writers," Martin wrote. "Every one of the four has visited me here in Santa Fe, some of them more than once, and we've spent days together discussing their ideas, the history of Westeros and the world beyond, and sundry details found only in The World of Ice & Fire and The Lands of Ice & Fire... when we weren't drinking margaritas and eating chile rellenos and visiting Meow Wolf. They are all amazing talents, and I am excited to be working with them. In between visits, I've been in touch with them by phone, text, and email, and I expect there will be a lot more back-and-forth as we move forward."
Don't expect David Benioff and D.B. Weiss to be involved now that they're Star Wars writers
Whichever show moves forward at HBO will likely boast Benioff and Weiss as producers due to contractual obligation (we wouldn't be here without them). What they won't be doing is lording over a writer's room; in February 2018, LucasFilm announced that the duo would spend the next stretch of their careers writing and producing a new series of Star Wars films. The deal is separate from the post-Last Jedi announcement that director Rian Johnson would helm is own, new trilogy.
"David and Dan are some of the best storytellers working today," said Kathleen Kennedy, president of Lucasfilm. "Their command of complex characters, depth of story and richness of mythology will break new ground and boldly push Star Wars in ways I find incredibly exciting." Thrones will miss them.
