As House of the Dragon fans begin to get restless about when they will get to see season three of the HBO show, one of the fantasy series' actors gives an update on when filming will take place. The long-awaited Game of Thrones prequel season two arrived in June last year and before anyone could say 'Dracarys', it was greenlit for a third and fourth season. Based on George R.R. Martin's novel Fire & Blood, House of the Dragon focuses on the fall of the House Targaryen as the clan ascends into a huge civil war where families are broken apart by greed and betrayal.
