The impressive cast of a series often changes. Sometimes it goes unnoticed, and sometimes it is quite surprising for the audience.
P.S. There is a little surprise that explains a lot at the end of the article.
9. Daario Naharis
In season 3, the role of Daenerys’s lover was played by the British actor Ed Skrein. Starting from season 4, this part has been played by the Dutch movie star Michiel Huisman. The official reason for Skrein leaving the series was him being too busy filming The Transporter Refueled. But Edward himself claims that he didn’t leave the show — it was a “behind-the-scenes decision.”
8. Beric Dondarrion
Australian actor David Michael Scott played Beric’s part in one scene in season one. Later, in season 3, he was replaced by Richard Dormer. No official reason was given.
7. Three-eyed Raven
The role of Three-eyed raven was first played by Struan Rodger, but he was never shown up close. In season 5, Oscar nominee Max von Sydow took his place, a decision the fans were happy with.
6. Tommen Baratheon
In the first 2 seasons, Cersei Lannister’s son was played by Callum Wharry. When his role was expanded in seasons 4 and 5, the creators of the show decided to change the boy for a more mature and experienced actor. Their choice fell on Dean-Charles Chapman (who played Martyn Lannister in season 3!).
5. Selyse Baratheon
We only saw Sarah MacKeever as Stannis Baratheon’s wife in a single scene of season 2. Later, when Selyse was “promoted” to the main cast, the actress was changed to Tara Fitzgerald.
4. Dickon Tarly
Freddie Stroma was playing Dickon in season 6, and it was planned that he would continue. However, because the actor was also filming Time After Time, he had to leave the show. This is how Tom Hopper became the face of House Tarly.
3. Night King
In seasons 4 and 5, Night King was played by Richard Brake. It was he who turned Craster’s son into a White Walker and commanded the army in Hardhome. Starting from season 6, he’s played by the Slovakian actor Vladimir Furdik.
2. Myrcella Baratheon
At first, Myrcella’s role was played by the Irish actress Aimee Richardson. Then her character disappeared for 2 seasons. In season 5, the role was given to Nell Tiger Free, for the same reason as Tommen’s replacement.
1. The Mountain
Throughout the series, The Mountain has been played by 3 actors. In season one, it was Australian actor Conan Stevens. He turned out to be too expensive and left Game of Thrones for The Hobbit. In season 2, he was replaced by stuntman Ian Whyte. And from season 4, he’s been played by professional strongman Hafþór Júlíus Björnsson.
No, Tirion was not replaced. We bet you can’t find another dwarf like that in Vesteros.
However, we should note that throughout the series there were some significant changes to Tirion — starting from his beard and ending with the russet in his hair.
