The untitled spinoff, directed by Naomi Watts, took place thousands of years before Game of Thrones and featured ancient ancestors of House Stark and House Lannister.
The series was shelved in October 2019 after shooting a pilot episode. This was followed by the revelation that a fresh take, House Of Dragon, based on George R.R. Martin’s book Fire & Blood, has been approved for a complete series.
Bob Greenblatt explained why the show was canceled, saying, “When I got there, they had spent almost $30 million on a Game of Thrones prequel pilot.”
“And when I saw a cutting of it a few weeks after I came, I told Casey, ‘this does not work, and I do not think it succeeds on the idea of the original show.'”
“And he did not argue, which was a comfort. But, as a result, we were forced to abandon it. There was a lot of pressure to get it perfect, and I am not sure it would have succeeded.”
Greenblatt also claims responsibility for the choice to renew House Of Dragon for a full season, which was rushed forth to prevent the excessive expenditures of another potentially disastrous pilot.
“They created the first pilot to defend their liability and preserve that brand, which I get,” Greenblatt said. “But it was vital that we somehow maintain that franchise and move rapidly, which meant putting the series into production immediately.”
“Which is always a nail-biter, although I think the next show is going to be fantastic.”
House Of Dragon, set 300 years before the events of Game of Thrones will be released in 2022 and will trace the emergence of House Targaryen.
