House of the Dragon Season 3 Casts Cullen, Sloane, Sibtain

The third season of HBO's House of the Dragon has added Tom Cullen, Joplin Sibtain, and Barry Sloane to its cast, with production currently underway in the UK. Cullen will portray Ser Luthor Largent, Sibtain will play Ser 'Bold' Jon Roxton, and Sloane is set as Ser Adrian Redfort, characters expected to bring new drama and action as the series continues to adapt George R.R. Martin's Fire & Blood. Returning cast members include Matt Smith, Emma D'Arcy, Olivia Cooke, and Rhys Ifans, while previously announced new additions feature James Norton, Tommy Flanagan, and Dan Fogler. Showrunner Ryan Condal remains at the helm with Martin as co-creator, and the upcoming season will consist of eight episodes. These new characters are anticipated to play significant roles in the evolving conflict between Queen Rhaenyra and King Aegon II Targaryen, with storylines involving the City Watch of King's Landing and campaigns in the Reach. The show continues to build anticipation after the success of its first two seasons.
