Not only are House of the Dragon’s dragon scenes more stunning, but the creatures are also considerably larger and more formidable than Daenerys’ dragons in Game of Thrones. Daenerys’ dragons Drogon and Viserion were only approximately seven years old by Game of Thrones season 8, meaning they’re not much different from the age of Lucerys’ dragon Arrax in House of the Dragon’s season 1 finale. Since Vhagar was able to wrap her teeth around and obliterate Arrax in one bite, Aemond’s dragon would have been able to take down Drogon, Viserion, and Rhaegal with far more ease.
Visual Effects Producer Nikeah Forde confirmed in the House That Dragons Built docuseries that Vhagar's enormous size is around 500 feet long in House of the Dragon, whereas Drogon was estimated to be about 230 feet long in Game of Thrones season 7 (via EW). While Vhagar was said to be five times larger than Arrax in George R.R. Martin’s Fire & Blood book, the size discrepancy seems far larger in House of the Dragon’s season 1 finale battle. As such, Daenerys’ dragons wouldn’t be the least bit intimidating to Vhagar despite their demonstrations of mass destruction in Game of Thrones.
As a recurring guest actor on The Big Bang Theory, one of Wil Wheaton’s favorite cameos involves an amusing mistake. In an episode that's also one of Big Bang Theory actor Johnny Galecki's favorites, season 3, episode 19, “The Wheaton Recurrence,” Wheaton, who plays a delightfully evil version of himself, is the captain of an opposing bowling team. He cunningly exploits the tension in Penny and Leonard's relationship to sabotage the game so Wil's team wins. Wheaton very much enjoyed this episode, even if it involved him making a bad miscalculation prior to the shoot.
