Tom Glynn-Carney, the actor behind King Aegon II Targaryen in House of the Dragon, has opened up about the intense pressure and personal philosophy that shaped his portrayal of the complex and deeply flawed Green king.
Quick read:
- Tom Glynn-Carney talked about the specific Aegon mantra he used for the role
- He talks about how he’s okay with not everyone liking his performance
- He addresses the discomfort of starting a new job everytime
In a candid new podcast with Before the Lights, Glynn-Carney revealed he joined the show late in season 1, taking over the role from young actor Ty Tennant. The sudden spotlight left him overwhelmed at first.
“I remember having a bit of a wobble on the first week of season 1… I came in quite late… And I remember that first week thinking, ‘F*ck me.’ It’s the amount of eyes on that job and what it means to the fans as well.”
He described feeling the immense weight of fan expectations, noting that “everyone has their version of what it is.”

The Aegon mantra
Instead of crumbling under pressure, Glynn-Carney made a firm pact with himself; a personal mantra that became central to his performance:
“Whatever people think it is, that’s fine, but they’re not doing it. I am. So it has to be down to what I think it is. If they’re on board with it, happy days. If they’re not, I apologize.”
This mindset allowed him to stop trying to please everyone and instead focus on his own interpretation of Aegon. Glynn-Carney also shared his broader acting philosophy, which he applied aggressively to the role:
“Almost every single time I accept a job, it’s like, ‘Oh shit, what have I done this for?’ … One of the big criteria for me at the moment is only accept the job if it terrifies you.”
He explained that choosing terrifying roles forces him to throw away insecurities, enter “survival mode,” and fully commit to the character. This approach clearly paid off.
From nervous replacement to fan favorite
Taking over a major role mid-production is never easy, especially in a global phenomenon like Game of Thrones. But Glynn-Carney’s willingness to embrace discomfort helped him deliver a nuanced Aegon. His honesty about the early struggles and the pressure of stepping into such an iconic franchise has resonated strongly with fans, many of whom now consider his version of Aegon definitive.
