When Maisie Williams first stepped onto the set of Game of Thrones, she was only 12 years old, a newcomer surrounded by veteran actors and one of the most ambitious television productions ever attempted. At that point, few people could have predicted that her character, Arya Stark, would become one of the most iconic figures in modern television. Yet behind Arya’s transformation into a fearless assassin was a remarkable level of dedication that many viewers never saw.
From the beginning, Williams approached the role with unusual seriousness for someone so young. While preparing for the character, she began studying George R. R. Martin’s A Song of Ice and Fire novels, where Arya’s personality and fighting style were described in far more detail than what initially appeared on screen. One small detail immediately caught her attention: Arya Stark was left-handed.
For many actors, that kind of detail might have seemed minor or even irrelevant to the overall performance. But Williams felt differently. If Arya was left-handed in the books, she believed the character should remain left-handed on screen. The only problem was that Williams herself was naturally right-handed.
Rather than asking the production team to ignore the detail, she made an unusual and demanding decision. She would retrain herself.
What followed was six months of intense and sometimes frustrating practice. Williams began deliberately switching everyday tasks to her left hand. She practiced writing, brushing her teeth, eating, and performing basic movements with her non-dominant hand. At first, even simple actions felt awkward and slow, but she pushed through the discomfort, determined to make the change feel natural.
The challenge became even greater once sword training began.
Arya’s combat style—known in the show as the “Water Dance”—was inspired by the fictional Braavosi sword-fighting technique taught by the character Syrio Forel. The choreography required precision, balance, and quick reflexes. Every movement had to appear fluid and instinctive, especially because Arya’s small size meant her fighting style relied heavily on speed and finesse rather than brute strength.
Learning that choreography is difficult even for trained stunt performers. Learning it with the opposite hand added an entirely new level of complexity.
Williams trained relentlessly with the stunt team, repeating drills and movements until they became second nature. Early sessions were reportedly filled with mistakes, dropped swords, and moments of visible frustration. But slowly, her left hand began to respond more naturally. Muscle memory developed, and the movements started to flow.
By the time filming required Arya’s early sword scenes, Williams had achieved something few actors attempt: she had effectively trained herself to fight ambidextrously.
The stunt coordinators on set were impressed by the commitment. Instead of relying heavily on stunt doubles, Williams was able to perform much of the choreography herself, maintaining the authenticity she had insisted on from the beginning. The result was a performance that looked strikingly natural on camera. Arya’s movements were sharp, agile, and believable—qualities that helped shape the character’s identity as one of the most dangerous fighters in the series.
As the seasons progressed and Arya’s storyline evolved into one of revenge, survival, and mastery of stealth, Williams’ early training continued to pay off. The foundation she built during those six months allowed her to handle increasingly complex fight sequences as the character matured.
Looking back, the decision might seem extreme for such a small detail. Yet it reflects a mindset that defined Williams’ portrayal of Arya Stark. Authenticity mattered, even when it required enormous effort behind the scenes.
By the time audiences watched Arya glide through combat with effortless precision, few realized how much work had gone into making those movements feel real. But that commitment—hours of training, countless repetitions, and a willingness to rewire her own habits—helped transform Arya Stark into one of television’s most unforgettable warriors.
