Variety has an exclusive scoop: HBO is actively considering a TV show about Aegon’s Conquest, which would take the Game of Thrones franchise back to the very beginning of the establishment of the Targaryen dynasty in Westeros. Per Variety:
As the project is in its very early stages, no writer is currently attached, though sources say that the search is underway as HBO is keen to move forward and get it into development. Sources also say that there may be a feature component to the project, i.e. HBO and Warner Bros. would produce a feature film that would then lead into the potential series, though plans remain in flux at present.
The full story of Aegon’s Conquest was first told in The World of Ice and Fire, which was later expanded with more information about the aftermath in Fire & Blood.
Years back, when George was sending us the material for the Targaryen kings for The World of Ice and Fire, he mentioned he could easily write a whole trilogy about these early Targaryen rulers, so there’s certainly a lot of possibilities. Almost six years ago, we even speculated on possible successors, and started our video on Westeros-based successors with Aegon’s Conquest. You can rewatch that here:
