History Trivia / HouseOfTheDragon

** Creator/EwanMitchell and Creator/PhiaSaban, who play Aemond and Helaena Targaryen, appeared in ''Series/TheLastKingdom'' together. Their characters in that show were also related, with Phia playing Ewan's niece.

* TheRedStapler: In a curious meta moment, a promotional interview snippet of Creator/EmmaDArcy naming a Negroni Sbagliato[[note]]The addendum "with prosecco" was just an elaboration on their part and is not necessary for ordering, as the prosecco ''is'' what differentiates a Negroni Sbagliato from a regular Negroni.[[/note]] their drink of choice has turned the cocktail into a social media sensation, prompting everyone from [=TikTokers=] to daytime talk show hosts to try the beverage.

* DuelingWorks: The series was released in summer 2022 just like another high profile FantasySeries in the post-''Series/GameOfThrones'' landscape, ''Series/TheLordOfTheRingsTheRingsOfPower'' (both premiered less than 15 days apart in August / September 2022). Both also happen to be {{prequel}}s set hundreds of years before a main saga/main MythArc. Interestingly, Creator/RyanCondal first developed a ''Franchise/ConanTheBarbarian'' series for Creator/{{Amazon}} at the same time as ''Rings of Power'', and that ''Conan'' series project ended up scrapped in favor of ''Series/{{The Wheel of Time|2021}}''. Condal then jumped ship at Creator/{{HBO}} and made ''House of the Dragon''. The duel carries over for Season 2 of both series 2024.

** The facial resemblance between Creator/EmmaDArcy and Creator/MillyAlcock (adult and young Rhaenyra respectively) is absolutely uncanny. They are also both very believable as the daughter of Sian Brooke (Aemma Arryn) and Creator/PaddyConsidine (Viserys).

** According to Creator/EmilyCarey, Alicent is in love with Ser Criston Cole.

** A mix of age-appropriate and Dawson casting is used strategically in the case of Laena Velaryon. When Laena's 12, she's played by also-12-year-old Nova Foueillis-Mosé to make her look ''way too young'' for Viserys to marry. At Rhaenyra's wedding, Laena is 15 and now played by 25-year-old Savannah Steyn. A decade later, when Laena is around 25, she's played by 35-year-old Creator/NannaBlondell. The ages of Savannah Steyn and Nanna Blondell both obfuscate that mathematically, Laena is uncomfortably young for Daemon to be pursuing. Daemon's later line to Rhaenyra, "I spared you. You were a child," lands differently if the audience remembers that he promptly turned around and pursued an even younger girl.

** Savannah Steyn played 15-year-old Laena Velaryon. The actress was born in 1996, so at least a decade older at the time of filming.

** Aegon's younger brother Aemond Targaryen is played by 25-year-old Creator/EwanMitchell.

** The scene of Daemon placing the crown on Viserys' head wasn't scripted, but was improvised during rehearsal by Smith and Considine after the crown accidentally slipped off Considine's head and ended up incorporated into the scene during filming.

** The scene of Daemon helping a weak Viserys to the throne wasn't scripted, but was improvised during rehearsal by Smith and Considine and ended up incorporated into the scene during filming.

* ThrowItIn: The shot of Alicent laughing at Otto, who is jokingly clapping at Jacaerys and Helaena, was actually unscripted, as Rhys Ifans had a reputation for making people laugh on set, and Olivia Cooke was actually laughing at him. Though it's not obvious as the voices are muted, Cooke is actually saying "Stop making me laugh".

* YouLookFamiliar: Creator/JeffersonHall, who plays twin brothers Jason and Tyland Lannister, also played a minor role in ''Series/GameOfThrones'' as Jon Arryn's former squire Ser Hugh.

** Minor example. Production of the show was halted several times due to positive cases on set during the UsefulNotes/COVID19Pandemic, although for less than a week each time (production started in April 2021, by then movie/TV productions had strong enough regulations and safety measures in place to avoid weeks/months-long shutdowns that plagued many TV and film productions in 2020). Otherwise, the creative team had an easier time than the ''Series/GameOfThrones'' showrunners, who had a lot of pressure being the first to try adapting the book saga of ''Franchise/ASongOfIceAndFire'' back in 2010-2011.
** In the "Making of Season 1" book that came out subsequently, Condal and his team admitted that filming during the pandemic was actually a nightmare, and they downplayed just how much is screwed up the early months of production. As Condal explained, it wasn't just that the set builders couldn't work in lockdown, the ''lumber mills themselves'' were in lockdown, so there was a global timber shortage and the price of construction materials skyrocketed. The famous three story set they build for the Red Keep wasn't even finished when it was supposed to be in April, and couldn't be used until June. Ultimately the way they worked around this was to hastily revise their filming schedule, to film all of the exterior on-location stuff first in spring, and then by summer the COVID lockdowns started to ease up and the sets were finally finished.
** Director Greg Yaitanes explained in a May 2022 interview that filming went quite smoothly, despite the ongoing COVID pandemic in 2021...up until the very end of the shoot. Exterior filming wrapped on schedule in early November, when they finished filming in Spain and Portugal. They still had a small number of important interior scenes they had to film, however, things that they couldn't simply cut for time. By early December, they were about "two weeks away" from a complete wrap...but then the COVID ''Omicron'' variant spiked in mid-December (which isn't nearly as harmful as prior variants but a ''lot'' more contagious). As Yaitanes put it, for the next ''three months'', they were perpetually "just two weeks away from being finished" -- but every few days a new crewmember would get the Omicron variant, then they'd have to shut down, then start up again, only to then shut down again. It was all the more frustrating because they had only a ''handful'' of scenes left to film, but it kept dragging on. Ryan Condal himself got COVID the same week they wrapped (right after Valentine's Day), and Yaitanes got COVID by May.

* CastingGag: Of the [[Series/DoctorWho Whovian]] variety. The young Aegon is played by Ty Tennant, the son of Creator/DavidTennant (who played the Tenth Doctor) and grandson of Creator/PeterDavison (who played the Fifth Doctor). Aegon's uncle Daemon is played by Creator/MattSmith, who played the Eleventh Doctor.
