Game of Thrones was more than just a TV series — it became a cultural phenomenon that redefined fantasy storytelling on television. The epic tale of the battle for the Iron Throne captivated millions, introduced legendary characters, and sparked endless debates over who truly deserved to rule Westeros.
One of the most iconic figures in the saga was Daenerys Targaryen — the last of the dragonlords, who transformed from a powerless exile into a formidable conqueror. For many, it's impossible to imagine anyone but Emilia Clarke in the role, as her charisma, tenderness, and inner strength made Daenerys a fan favorite.
However, the role of Daenerys Targaryen was originally given to Tamzin Merchant (known for Carnival Row, The Tudors, Jane Eyre). She even filmed the pilot episode before being replaced by Emilia Clarke. The exact reasons for the recasting remain undisclosed, but speculation suggests that either Merchant herself did not fully connect with the role, or the showrunners felt they needed a different energy for the character.

Another actress who auditioned for the role was Elizabeth Olsen (yes, Wanda from Marvel). However, her audition didn’t go well, and she later admitted that her tryout for Daenerys was "terrible".
