HBO Exec #1: “Three words: Game of Thrones spinoffs.”
HBO Exec #2: “Are we sure? By the way, that’s four words. We saw massive success with Big Little Lies, and with the rise of streaming services, our prestige drama reputation is slowly slipping away. That’s the path we need to be on.”
HBO Exec #1: “You like money, right?”
HBO Exec #2: “Yeah.”
HBO Exec #1: “Then shut the f@#k up.”

Per Variety:

HBO has closed deals with four different writers to explore multiple possible spinoffs of “Game of Thrones.”

The premium cable channel says that there is no timeline for development of the projects. “We’ll take as much or as little time as the writers need and, as with all our development, we will evaluate what we have when the scripts are in,” a spokesperson said.

The four writers are Max Borenstein (“Kong: Skull Island”), Jane Goldman (“Kingsman: The Golden Circle”), Brian Helgeland (“Legend”), and Carly Wray (“Mad Men,” “The Leftovers”). Goldman and Wray will each be working individually with novelist and “Game of Thrones” creator George R. R. Martin.

“Game of Thrones” executive producers and showrunners Dan Weiss and David Benioff will be attached to the four projects, as will Martin, but will not write on any of them.

A spinoff to “Game of Thrones” — the most watched series in HBO history — has been a source of speculation for years. In recent months, HBO executive began to privately acknowledge that the network was searching for writers to develop ideas based on the series and Martin’s best-selling fantasy novels from which it is adapted.

Where’s George R.R. Martin’s involvement in all of this? Oh, right…
