Henry Cavill is everywhere these days. Cavill is in both Enola Holmes films and he's still set to appear for one final season of The Witcher next year. He's also going to be a part of the DC Universe going forward after rejoining the live-action cinematic universe as Superman.
But, while Cavill will be a mainstay in the mainstream consciousness for several more years, one show we won't be seeing him in is House of the Dragon.
Due to the collective creativity of the internet, fans edited Cavill as Aegon Targaryen riding atop the Black Dread, Balerion. Although he does fit the part of the man who conquered Westeros and united the Seven Kingdoms (well, six, considering the Dorne maintained its independence), Cavill won't be part of the hit HBO show anytime soon.
Cavill joined Josh Horowitz's Happy, Sad, Confused podcast where he denied talks that he's joining the Game of Thrones universe.
