Before House of the Dragon existed, HBO had already invested in a Game of Thrones spin-off called Blood Moon, casting Naomi Watts and Jamie Campbell Bower and filming an entire pilot episode in 2018. The show was scrapped, making House of the Dragon the second attempt at extending the franchise. Many of TV's biggest hits weren't the original plan — they emerged only after a previous version died.
