Early Life & Education
Harry Collett was born on January 17, 2004, in Havering, a suburban borough in East London, England. He grew up in a close-knit family with his mother, Marie Collett, and younger sister, Brooke Collett.
From an early age, Harry showed a natural flair for performing. He attended Coopers’ Company and Coborn School in Upminster, London, where he completed his secondary education and finished Year 11 in 2020. His school was incredibly supportive of his acting career — in January 2020, they even hosted a special premiere screening of his film Dolittle at Vue Cinema for friends and family, celebrating his performance alongside Robert Downey Jr.
Harry’s passion for the stage ignited when he was just six years old, leading him to begin his professional acting career on London’s prestigious West End — one of the most competitive theater districts in the world.
Career Journey
West End Beginnings (2010–2016)
Harry Collett’s acting journey began on the stage, where he honed his craft as a child performer in some of London’s biggest musical productions. His professional debut came in 2010 at the tender age of six, when he played the Small Boy in Billy Elliot the Musical at the Victoria Palace Theatre.
In 2013, he joined the cast of Matilda the Musical at the Cambridge Theatre, playing the role of Eric. Then, from 2015 to 2016, he starred as Michael in Elf the Musical at the Dominion Theatre — a role that showcased his singing, dancing, and comedic timing to West End audiences.
Television Breakthrough: Casualty (2014–2022)
Harry made his television debut in 2014 with a guest appearance as Seb Durante in an episode of the long-running BBC medical drama Casualty. But it was his casting as Oliver Hide in 2016 that truly put him on the map. Oliver was the son of established character David Hide (played by Jason Durr), and Harry’s performance immediately impressed both critics and co-stars.
His Casualty run was intermittent but impactful. He reprised the role in 2017, 2019, and 2021, before returning in 2022 for a dramatic four-episode arc that concluded with his character’s tragic death during a school shooting in episode 39 of series 36. Co-star Jason Durr praised Harry effusively, calling him “absolutely fantastic” and predicting, “He’s got a great career ahead of him.”
Voice Work & Early Screen Roles (2014–2018)
Between stage and TV commitments, Harry built an impressive voice acting portfolio. He voiced Wally in Wallykazam! across the first two series on Nick Jr. Channel and Buzzbee in The Hive on CITV. He also voiced a younger version of Raymond Briggs in the animated biographical film Ethel & Ernest (2016).
In 2014, he appeared as a younger Michael Bublé in the music video for Bublé and Idina Menzel’s cover of “Baby, It’s Cold Outside.” He made guest appearances in ABC’s musical comedy Galavant (2015) as Young Galavant and had a cameo in Christopher Nolan’s epic war film Dunkirk (2017). He also appeared in the short film Honour (2017) and Dead in a Week or Your Money Back (2018).
Hollywood Breakthrough: Dolittle (2020)
In December 2017, Harry landed the role that would introduce him to global audiences: Tommy Stubbins, the young apprentice to Dr. Dolittle, played by Robert Downey Jr. The adventure comedy Dolittle was released in January 2020, and Harry held his own alongside an all-star cast including Antonio Banderas, Michael Sheen, and a voice cast featuring Emma Thompson, Rami Malek, and Tom Holland.
The Role of a Lifetime: House of the Dragon (2022–2026)
Harry’s career reached stratospheric heights when he was cast as Prince Jacaerys “Jace” Velaryon in HBO’s House of the Dragon, the highly anticipated prequel to Game of Thrones. The casting process was shrouded in secrecy — his first self-tapes were labeled “Untitled HBO Series,” and his character was called “Jack.” It wasn’t until his final in-person audition that he learned he was auditioning for a Game of Thrones spin-off.
In Season 1 (2022), Jace appeared in a handful of episodes as the eldest son of Rhaenyra Targaryen (Emma D’Arcy), heir to the Iron Throne. But it was Season 2 (2024) where Harry truly came into his own. Jace evolved from a background prince to a central political figure, proposing the dragonseed strategy and engaging in deeper, more adult conversations with his mother. His natural curls — grown out over a year and a half — became a signature look, styled to evoke Jon Snow on the Wall.
Season 3 (2026) brought Jace’s tragic but heroic end. In the season premiere, the Battle of the Gullet, Jace finally got to shout “Dracarys!” — a moment Harry specifically requested — before dying in a dramatic dragon battle. His death scene, filmed in water tanks at Leavesden Studios, was physically grueling but emotionally powerful. Showrunner Ryan Condal gave Harry “the death call” to prepare him, and his final day on set was emotional, with co-stars Emma D’Arcy and Matt Smith coming to say goodbye. He received wrap gifts including a 3D model of Vermax’s head and Jace’s sword.
Upcoming: Easy (2025)
In July 2025, Harry was confirmed as the male lead opposite Lizzy Greene (Ransom Canyon) in Easy, a film adaptation of Tammara Webber’s bestselling new adult novel. He plays Lucas Maxfield, an enigmatic college student with a troubled past who becomes an unexpected source of strength for Jacqueline (Greene) after a traumatic event. Filming wrapped in Malta, and the project is currently in post-production.

Interesting Facts
- Real Hair, Real Curls: Unlike most of the House of the Dragon cast who wore wigs, Harry’s signature curly brown locks in Seasons 2 and 3 are entirely his own. He grew his hair for a year and a half after being told to start growing it out immediately after his Season 1 wig fitting.

- Dracarys Moment: Harry specifically asked showrunner Ryan Condal if he could say “Dracarys!” in the Season 3 premiere — his first and only time using the iconic High Valyrian command. It wasn’t originally in the script.
- Seven Seconds of Fame: His cameo in Christopher Nolan’s Dunkirk lasted approximately seven seconds, but he dreams of working with the director again in a proper role.
- West End Prodigy: He made his professional stage debut at age six in Billy Elliot the Musical — one of the most demanding shows in London theater.
- From West End to HBO: He is one of the few child actors to successfully transition from West End musicals to a major HBO fantasy series lead.
- Music Producer: He bought his first DJ decks impulsively at a rave in London and taught himself to produce house music during the House of the Dragon Season 1–2 hiatus.
- Never Watched Game of Thrones: Despite starring in its prequel, Harry had never watched the original Game of Thrones series when he auditioned, as he was too young. He still plans to watch it someday.
