Get To Know the New Cast Members of ‘House of the Dragon’!

As House of the Dragon entered its final time jump last week, it ushered in a new wave of actors that are here for the long haul. The show’s new generation of Targaryen children are now young adults (with the exception of three) bound to have more prominent roles to play in coming episodes. Here’s a look into the actors’ previous works you may recognize them from!

With episode eight of House of the Dragon, the show has finally surpassed all the major time jumps, leaving the recast we have now for the remainder of the show’s story — or, at least until a character meets their demise. The next generation of Targaryens are now aged up to young adults that are sure to take center stage during the Dance of the Dragons civil war, and these are the faces to remember. Already familiar with the adult actors, let’s take a look at the ones portraying their on-screen children!

The young British actor Harry Collett assumes the role of Rhaenyra and Laenor’s eldest son Jacaerys “Jace” Velaryon. His earliest works include stage productions for London’s West End theatre, for the shows Billy Elliot the Musical, Matilda The Musical, and Elf. While House of the Dragon seems to be his breakout role, he’s had minor roles in other TV shows. For instance, in the BBC show Causality — the longest-running primetime medical drama in the world — he made his TV debut, originally playing a character for one episode, “A Life Less Lived” in 2014, and later came back in 2016 to portray the recurring role of Oliver Hide for 22 episodes. Additionally, he’s had a couple voice acting roles: the 2015 five-episode long presence of Buzzbee in British CG animated children’s show The Hive, and had the lead role of Wally Trollman in Wallykazam!, an interactive animated children’s show for Nickelodeon.

Collett’s film debut was a voice role of the Young Raymond Briggs in 2016’s animated biographical Ethel & Ernest. He also had a cameo as a young boy in Christopher Nolan’s Dunkirk in 2017, and appeared the following year in the British black comedy Dead in a Week or Your Money Back as Young William. His leading film role came in 2020’s Dolittle as Robert Downey Jr. ‘s Dr. Dolittle’s self-appointed apprentice Tommy Stubbins. Worth mentioning is his role depicting Young Michael Buble in his and Idina Menzel’s music video for “Baby, It’s Cold Outside” in 2014.

Collett’s new Targaryen role breaks him out of the mold of being the younger version of another actor, as he finds himself as the face of the character moving forward. The actor can be found on Instagram @harrycollettactor

Elliot Grihault finds himself as the second “Strong boy” of Rhaenyra’s, Lucerys “Luke” Velaryon. The 16-year-old is largely undiscovered, landing his first big name role in House of the Dragon. However, like his on-screen older brother, he was also involved in a London West End production. His sole previous acting credit is as a Young Harry Potter in the British two-part play Harry Potter and the Cursed Child. Considering his younger counterpart took out Aemond’s eye in episode seven, Grihault’s Luke is sure to have a tense role to play in coming events.

Tom Glynn-Carney is a 27-year-old English actor and singer who landed the role as Alicent’s oldest, the first born son of King Viserys who will be pushed by his mother’s loyalists to assume the rule of the Iron Throne. The show’s next-gen actors have a lot of similarities with their acting careers, as Glynn-Carney also had a two-episode role in Casualty in 2013, his first TV experience. He had a main role as Lance Corporal Tony Armstrong in mini series The Last Post, about a British army unit during a Yemeni independence fight and the women and children there with them. In 2018, he was in the British TV crime drama movie Doing Money as the character Sean. Based on the Jason Johnson novel Slave, it focused on subject matter surrounding modern day slavery in the sex trade.

Unlike Collett, Glynn-Carney is perhaps most notable for his film debut role in Dunkirk as Peter Dawson. He’s considered a supporting character from the war movie’s ensemble cast. He also played Christopher Wiseman in the 2019 biographical drama Tolkien about the author of The Hobbit and The Lord of the Rings, J.R.R. Tolkien, which stars Nicholas Hoult and Lily Collins. Coincidentally, Ty Tennant played the younger version of Gynn-Carney’s character in this movie, just like he portrayed the younger version of Aegon II in episodes six and seven. Similar to the monarchy atmosphere of Westeros, Glynn-Carney also starred in the 2019 King Henry V movie The King as Sir Henry “Hotspur” Percy, which features Timothee Chalamet, Joel Edgerton, Robert Pattinson, and Lily-Rose Depp.

The actor won the Emerging Talent Award at the Evening Standard Theatre Awards in 2017 for the play The Ferryman, originating at the Royal Court Theatre and transferring to the Gielgud Theatre. He played Shane Corcoran, alongside his House of the Dragon on-screen dad Paddy Considine. Additionally, he’s the lead singer of indie band Sleep Walking Animals.

English actor Ewan Mitchell takes over as Aemond “One Eye” Targaryen, the youngest child of Alicent and Viserys. Like his on-screen sister, he too was in The Last Kingdom, best known as the character Osferth, from seasons two through five.

The show was set at a five-star hotel during World War II, showing the impact it had on London Society. Mitchell starred in 2019 British war drama series World on Fire as Tom Bennett, airing later in the US in 2020, which is commissioned to have a second season. British crime thriller Trigger Point, another show ordered for a second season earlier this year, has Mitchell featured in three episodes as Billy Washington.

As for movies, he’s known for his role as Ettore in 2018’s High Life, a sci-fi A24 horror with Robert Pattinson and Mia Goth.

24-year-old Bethany Antonia plays Baela Targaryen, one of two daughters of Daemon and Laena (and Rhaenyra’s stepdaughter). She’s credited for a few previous roles, such as two movies Pin Cushion in 2017 and There’s Always Hope in 2021. In the first — which is about a mother and daughter living in their own fantasy world after becoming the town’s bullying targets — she plays the character Chelsea. In the second, she assumes the role of Pen in a comedy drama where a woman travels to Portugal to mend her parents’ relationship. Antonia is perhaps most notable for her roles in two other TV series. She played Margot in Netflix’s Get Even in 2020 — originally a British premiere on BBC iPlayer — which is about four private school girls who expose bullies by forming a secret society. Then in 2021, she was Kayleigh Shaw in miniseries Stay Close, a British mystery thriller based on the 2012 Harlan Coben novel.

Phoebe Campbell


Phoebe Campbell plays Baela’s sister Rhaena. She has had a few previous minor roles, such as Tara Lockston in the Midsomer Murders episode “Crime and Punishment” and Petra in the “Pilot” episode of Home from Home. Campbell can also be seen in the 2016 TV movie The Last Dragonslayer and the 2016 short film Heart’s Ease. House of the Dragon hasn’t shown too much about Daemon’s daughters, but now betrothed to Jace and Luke, they are sure to have a further role to play as dragonriders.
