HBO is moving forward with its Game of Thrones spin-off, House of the Dragon. The prequel series was initially confirmed in October 2019, with the network giving the show a series order. While much remains mysterious about the return to Westeros, it has been revealed that casting has begun for the series. How, precisely, the casting process is proceeding, given the limitations presented by the current situation, hasn't been revealed, but this is a big step in the right direction for the show.

According to a new report, House of the Dragon has commenced with the casting process. Unfortunately, few additional details were made available at this time. There is no word on specific actors being looked at, nor is there any word on what roles these actors will fill. We know that the show will center on House Targaryen. The report notes that King Viserys I, Princess Rhaenyra Targaryen, Queen Alicent Hightower and Aegon II Targaryen were all part of the Targaryen Civil War. That means they are likely candidates for inclusion, but nothing has been confirmed just yet.


The show will be based on George R.R. Martin's Fire & Blood. The Game of Thrones prequel ill tell the story of House Targaryen, taking place 300 years before the events of the main series, which concluded its run last year. The book begins their tale with the legendary Aegon the Conqueror, creator of the Iron Throne. It goes on to recount the generations of Targaryens who fought to hold that iconic chair, all the way up to the civil war that nearly tore their dynasty apart. The source material is plentiful and will provide HBO with a lot to work with.

Ryan Condal (Colony, Hercules) co-created the series alongside George R.R. Martin. It is just one of several spin-offs that the network had in development. At one point, it was said that as many as five different ideas for new Game of Thrones shows were floating around. HBO previously filmed a pilot for a different prequel, set thousands of years before the main show, with Naomi Watts in the lead role. Ultimately, the network opted not to move forward with that version and went in a different direction. They seem to have a lot more confidence in Condal's version, as HBO didn't shoot a pilot, giving it a straight-to-series order.


Game of Thrones ran for eight seasons from 2011 to 2019. While many fans were rather unhappy with the final season, especially the series finale, it remains one of the most popular shows in TV history. With that, HBO was eager for a continuance of some sort. While there is no word yet on a specific premiere date, HBO's President of Programming Casey Bloys previously stated that they expect House of the Dragon to debut sometime in 2022. We'll be sure to keep you posted as any further details are made available. This news comes to us via Entertainment Weekly.
