After the loss of Helen McCrory, the emotional landscape of Peaky Blinders was forever changed. McCrory’s portrayal of Polly Gray had been the moral and emotional backbone of the Shelby family—a presence that grounded even the most chaotic moments. For the cast, her absence was not just professional, but deeply personal.
Among those most affected was Sophie Rundle, who played Ada Thorne.
Rundle had shared countless scenes with McCrory, often portraying a dynamic where Ada learned, resisted, and ultimately grew under Polly’s influence. Off-screen, that relationship carried a similar weight. McCrory had been a guiding force, someone whose strength and presence shaped the tone of the entire set. Without her, Rundle found herself facing a daunting question: how do you move forward when the person who anchored the story is no longer there?
At first, her instinct was to step back.
The emotional weight of continuing without McCrory felt overwhelming. Rundle reportedly questioned whether she could carry the responsibility that Polly had once held. Rather than risk falling short, she considered asking for a smaller role—something that would allow her to remain part of the story without having to fill a space that felt impossible to replace.
But the production team saw something different.
They didn’t see absence—they saw evolution.
Instead of reducing her presence, they elevated it. Ada Thorne was no longer just a supporting voice within the Shelby family; she became its center. The narrative shifted, placing her at the heart of the Shelby empire’s political future. It was a bold decision, one that required Rundle to step into a role defined not by imitation, but by transformation.
And she accepted.
What followed was not an attempt to recreate Polly Gray, but to honor her legacy through growth. Rundle’s performance carried echoes of McCrory’s strength—measured, intelligent, and commanding—but it also introduced something new. Ada’s power was quieter, more calculated, shaped by years of observing the world around her.
She wasn’t replacing Polly.
She was becoming something else entirely.
During a pivotal moment set in the Small Heath office, that transformation became undeniable. The atmosphere was tense, the weight of leadership hanging heavily in the air. Ada stood not as a sister or a bystander, but as a figure of authority. The crew reportedly felt the shift instantly—this was no longer the Ada they had known in earlier seasons.
Then came the line.
Four words that defined everything she had become:
“I am a Shelby.”
It wasn’t shouted. It didn’t need to be.
The power was in its certainty.
Those words carried generations of legacy, struggle, and resilience. They signaled that Ada had fully stepped into her place within the family—not as someone overshadowed by others, but as a leader in her own right. It was a declaration not just of identity, but of readiness.
For Rundle, that moment represented more than character development.
It was personal.
It was about finding strength in the face of loss, about honoring someone who could never be replaced by choosing to move forward rather than retreat. By embracing the role, she ensured that Polly Gray’s influence didn’t disappear—it evolved.
In the end, Sophie Rundle didn’t fill Helen McCrory’s shoes.
She walked her own path.
And in four simple words, she proved she was ready to carry the weight of the Shelby name.
