A relative newcomer reportedly joining these actors on screen is 20-year-old Ty Tennant, the son of Doctor Who star David Tennant and his wife, the actor Georgia Tennant.
The Game of Thrones prequel series, House of the Dragon, stars many famous faces – from Matt Smith and Paddy Considine to Olivia Cooke.
David adopted Georgia’s son Ty back in 2011, the same year the couple got married.
Georgia was referring to the Neil Gaiman fantasy series, in which David stars as demon Crowley and Michael Sheen appears as angel Aziraphale.
