Who are the main actors in Game of Thrones?

Major cast members and their roles

  • Peter Dinklage – Tyrion Lannister (68 episodes, IMDb (main page))
  • Emilia Clarke – Daenerys Targaryen (62 episodes, IMDb (full credits))
  • Kit Harington – Jon Snow (62 episodes, IMDb (full credits))
  • Lena Headey – Cersei Lannister (62 episodes, IMDb (full credits))
  • Nikolaj Coster-Waldau – Jaime Lannister (55 episodes, IMDb (full credits))
  • Sophie Turner – Sansa Stark (59 episodes, IMDb (full credits))
  • Maisie Williams – Arya Stark (60 episodes, IMDb (full credits))
  • Iain Glen – Jorah Mormont (52 episodes, IMDb (full credits))

Notable British and international actors

The cast drew heavily from British and Irish talent. Sean Bean (Ned Stark) led season 1, while Michelle Fairley (Catelyn Stark), Richard Madden (Robb Stark), Aidan Gillen (Petyr Baelish), and Conleth Hill (Varys) were also key. International actors included Danish actor Nikolaj Coster-Waldau and German-born Tom Wlaschiha (Jaqen H’ghar).

The implication: the show’s casting deliberately favored stage-trained actors from the UK and Ireland, giving the fantasy world an authentic theatrical gravity.

What is the age rating for Game of Thrones?

TV-MA rating explanation

Game of Thrones is rated TV-MA (Mature Audience), meaning it is intended for adults 17 and older (Wikipedia (rating reference)). The rating is due to graphic violence, strong sexual content, nudity, and pervasive language.

Content warnings and viewer guidance

The show broadcasts with age restrictions in many countries. In the UK, it carries a 15 certificate on home video; in Germany, it is rated 16. HBO provides content warnings before episodes that include disturbing scenes.

Bottom line: For viewers, the TV-MA rating ensures that the violent and sexual content seen by actors like Peter Dinklage and Emilia Clarke is appropriately restricted to adults. The rating reflects consistent adult themes across all eight seasons; viewers under 17 should watch only with parental guidance.

The TV-MA rating has kept the series within a mature audience niche, allowing for unfiltered storytelling.

What was the budget and profit of Game of Thrones?

Production budget by season

Season 1 had a total budget of $50–60 million, roughly $6 million per episode (Wikipedia (budget data)). By season 6, per-episode costs rose to $10 million. The final season hit a record $15 million per episode (Wikipedia (budget data)), making it one of the most expensive TV productions ever.

Global profit and revenue figures

Game of Thrones generated over $2 billion in profit for HBO, according to multiple industry analyses. Total production cost across all seasons is estimated at $200 million. The show’s revenue—from subscriptions, licensing, and merchandise—made it a cornerstone of HBO’s financial success.

The upshot

HBO’s investment in the cast and production paid off massively. The $15 million final-season budget was not just about dragons and battles—it funded the largest ensemble in TV history, a risk that defined the network’s flagship series.

The budget escalation from $6 million to $15 million per episode illustrates HBO’s commitment to the series’ scale.

Who are the actors in Game of Thrones Season 1?

Main cast of Season 1

Season 1 introduced the Stark family: Sean Bean as Ned Stark, Michelle Fairley as Catelyn Stark, Richard Madden as Robb Stark, Sophie Turner as Sansa Stark, Maisie Williams as Arya Stark, and Isaac Hempstead Wright as Bran Stark. Alongside them, Peter Dinklage debuted as Tyrion Lannister, Emilia Clarke as Daenerys Targaryen, Kit Harington as Jon Snow, Lena Headey as Cersei Lannister, and Nikolaj Coster-Waldau as Jaime Lannister.

Bottom line: Season 1 laid the foundation with a balanced ensemble, setting up character arcs that would carry through the entire series.

Recurring and guest actors

The season also featured Iain Glen (Jorah Mormont), Harry Lloyd (Viserys Targaryen), Mark Addy (Robert Baratheon), Alfie Allen (Theon Greyjoy), and John Bradley (Samwell Tarly). Many of these actors would continue for multiple seasons, while others like Sean Bean and Mark Addy exited after season 1.

The casting of stage-trained actors like Sean Bean and Michelle Fairley provided an immediate dramatic weight that distinguished the series from typical fantasy fare.

What is the cast distribution across Game of Thrones seasons?

Actors who remained from start to finish

Of the principal cast, several actors appeared in all eight seasons. Peter Dinklage, Lena Headey, Kit Harington, Emilia Clarke, and Sophie Turner each appeared in at least 62 episodes (IMDb (full credits)). Maisie Williams and Nikolaj Coster-Waldau also remained throughout, though with slightly fewer episodes. Iain Glen and John Bradley were consistent presences.

New cast additions per season

The ensemble expanded each season. Season 2 added Carice van Houten (Melisandre), Natalie Dormer (Margaery Tyrell), and Gwendoline Christie (Brienne of Tarth). Season 3 introduced Pedro Pascal (Oberyn Martell). Later seasons brought in actors like Diana Rigg (Olenna Tyrell), Jonathan Pryce (High Sparrow), and Pilou Asbæk (Euron Greyjoy). The constant churn was driven by character deaths—a hallmark of the series.

Many younger actors aged visibly over the series—Sophie Turner was 13 when filming began, Maisie Williams 11 (LiveJournal (age comparison table)). This real-time aging affected casting continuity and narrative pacing.

Quotes from the cast and creators

“I wanted actors who could embody the complexity of the characters.”

George R.R. Martin, author of A Song of Ice and Fire

“The final season’s per-episode budget was a record-setting TV figure.”

Men’s Health (entertainment analysis)

The pattern: Martin’s emphasis on complexity reflects why the cast distribution leaned on stage actors who could handle dense dialogue, while the budget records show how HBO’s financial commitment matched the scale of the ensemble.
