Why Game of Thrones spin-off Bloodmoon was cancelled – HBO explains

According to a new article in The Hollywood Reporter, showrunner Jane Goldman was confident of a full season order, but the plug was suddenly pulled last year with little explanation.

As House of the Dragon prepares to launch, creatives involved in both projects have shed light on the change in focus, with the consensus being that they initially wanted to move away from the premise of the original Thrones (i.e. a royal power struggle), which Goldman's show provided.

“Bloodmoon really stood out as different, with unique world-building," said Francesca Orsi, HBO’s Executive VP of Drama. "Tonally it felt very adult, sophisticated and intelligent."

However, a feeling soon grew that the show was perhaps too far removed from what audiences – and even creator George RR Martin knew – as it took place during a time period that the author himself had barely ever explored.

"Bloodmoon was a very difficult assignment,” he said. “We’re dealing with a much more primitive people. There were no dragons yet. A lot of the pilot revolved around a wedding of a Southern house to a Northern house and it got into the whole history of the White Walkers.”

HBO's Chief Content Officer Casey Bloys and WarnerMedia's former chairman Robert Greenblatt agreed that Bloodmoon was very well produced, but simply not what the network was looking for from the first ever spin-off in its history.

"It didn’t take me to the same place as the original series," Greenblatt said. "It didn’t have that depth and richness that the original series’ pilot did.”

THR's investigation reveals that George RR Martin still hasn't seen the Bloodmoon pilot, while also uncovering ideas for other abandoned Game of Thrones spin-offs, including an adaptation of Martin's light-hearted Dunk and Egg stories, following a knight and his young squire, and the fabled adventures of the Seven Gods of Westeros (scrapped early in development).
