Games Of Thrones prequel House Of The Dragon may have just premiered, but creators have already confirmed that a second season will be coming to television.

The HBO production, available to watch via Foxtel and Binge in Australia, is setting viewing records, with the first episode becoming HBO’s biggest debut ever, attracting over 20 million viewers within the first four days.

Creator George R R Martin had already discussed the likelihood of a second season at a recent Comic-Con panel, but this is the first confirmation from HBO.

House Of The Dragon is based on the George R.R. Martin novel Fire & Blood, and is set 200 years before the events of the Game Of Thrones.

It stars Paddy Considine (The Third Day), Matt Smith (The Crown), Olivia Cooke (Ready Player One), Emma D’Arcy (Truth Seekers), Steve Toussaint (Doctor Who), Eve Best (Nurse Jackie), Sonoya Mizuno (Ex Machina), Fabien Frankel (The Serpent) and Rhys Ifans (Notting Hill), as well as two Aussie stars: Milly Alcock (Upright) as Young Princess Rhaenyra Targaryen and Ryan Corr (Packed to the Rafters) as Ser Harwin ‘Breakbones’ Strong.
