'House of the Dragon' cast talk balance of old and new

Stars of "House of the Dragon" say the team behind the prequel intend to satisfy "Game of Thrones" fans, while setting out their own stall with an original story. The new series will focus on House Targaryen, made famous in "Game of Thrones" by Emilia Clarke's Daenerys and her fearsome dragons. (Aug. 8) (AP Production by Andrew Bray)
