When Emilia Clarke debuted as Daenerys Targaryen in the first season of Game of Thrones, she was 24 years old. Her character, however, started the story much younger—roughly 16 on screen and a mere 13 in George R.R. Martin's original source novels. This massive gap between actor and character is a hallmark of television adaptations, where child labor laws, maturity requirements, and narrative pacing force showrunners to age up their casts.
Understanding how old Emilia Clarke was during production helps contextualize the grueling physical demands, rapid career trajectory, and complex emotional weight she carried from day one. Let's break down the realities of her casting, how her age compared to both her character and co-stars, and why this specific casting choice shaped the entire trajectory of the HBO hit.
Emilia Clarke's Real Age During Season 1 Production
Emilia Clarke was born on October 23, 1986. Principal photography for the first season of Game of Thrones took place primarily between July and November 2010, meaning Clarke was 23 years old when shooting began and turned 24 midway through post-production.
At the time, Clarke was a relatively unknown graduate of the Drama Centre London with only minor television credits to her name. She stepped into the role under intense pressure after Tamzin Merchant, the actress originally cast as Daenerys in the scrapped pilot episode, exited the project. Clarke secured the part, dyed her hair platinum blonde, and instantly became the anchor for one of fantasy television's most transformative character arcs.
Character Age vs. Actor Age: The Daenerys Discrepancy
The discrepancy between Emilia Clarke's age and Daenerys Targaryen's age is stark. In A Game of Thrones, the first book in the A Song of Ice and Fire series, Daenerys is only 13 years old at the start of her wedding to Khal Drogo.
Recognizing that adapting such ages literally for television would be problematic and unfeasible for a mainstream audience, showrunners David Benioff and D.B. Weiss aged up nearly all of the younger characters. In the television adaptation of season 1, Daenerys is introduced as being around 16 years old.
- Book Age: 13 years old
- Show Age: Approximately 16 years old
- Actor's Real Age: 24 years old
This decision allowed the production to handle mature thematic material responsibly while giving Clarke the professional maturity required to carry high-stakes dramatic scenes.
How Clarke Compared to Other Young Cast Members
The casting of Game of Thrones relied on a mix of veteran British stage actors and young newcomers. While Clarke was in her mid-twenties, other actors playing teenagers were much closer to their characters' actual ages, creating unique dynamics on set.
- Maisie Williams (Arya Stark): Started filming at just 13 years old, matching the youth of her book character much more closely.
- Sophie Turner (Sansa Stark): Began the series at 14 years old, playing an eleven-to-twelve-year-old Sansa.
- Kit Harington (Jon Snow): Was 23 during season 1 production, playing a character intended to be around 14 in the books and 17 in the show.
Because Clarke was 24, she had already completed formal theatrical training, which helped her navigate the intense physical demands of the role, including stunt work, demanding emotional sequences, and extensive dialogue in Dothraki, a constructed language created specifically for the show.
Common Misconceptions About the Cast Ages
Viewers often conflate the ages of the actors with the medieval chronology of Westeros. Several persistent myths surround the early seasons of the show.
- The "Child Bride" Myth on Set: Because book readers know Daenerys is 13, many casual viewers mistakenly assume Emilia Clarke was also a minor during season 1. In reality, Clarke was an adult in her mid-twenties, ensuring strict adherence to workplace regulations.
- The Recasting Confusion: Because the original pilot featured a different actress (Tamzin Merchant), some historical timelines blur. Clarke was the sole face of Daenerys for the broadcast version of season 1 onward.
- Uniform Aging: Fans often assume all young characters were aged up by the exact same amount. While Daenerys and Jon Snow were aged up by roughly three to four years on screen, younger actors like Maisie Williams grew up literally on screen across the show's eight-year run.
