HBO announced its decision to renew the fantasy drama on Aug. 26, 2022, and rumors about the 

cast of Season 2 have already started swirling. Is Avengers and WandaVision actress 

Elizabeth Olsen about to show up in full kit in Westeros? How about Henry Cavill? We investigate.

The rumors about Elizabeth and Henry making their debut on House of the Dragon 

were seemingly brought on thanks to one humble tweet posted @GeekVibesNation on Sept. 4, 2022.

While it's uncertain who exactly caught wind of the brazen casting decision first, one thing is

certain: House of the Dragon fans would love to see the Marvel veteran and The Witcher lead in the show.

Unfortunately for fans, Elizabeth has already pledged to never join Instagram

again — which means that she likely won't address the casting rumors on social media.
