The Game of Thrones prequel, House of the Dragon, has been in the works for a while, and it is one of the many productions that has had some COVID-related difficulties. However, it appears HBO is powering through with the series, which will draw inspiration from George R.R. Martin’s novella Fire & Blood, and follow the rise of the Targaryen family. The cast for the series keeps growing, in fact, the official Twitter account for the show just announced seven new cast members.
