2. Core trio emerges later, anchoring the story emotionally.
3. Expansion into wider Hogwarts including family, staff, and peers.

This vertical casting strategy:
– Root the adaptation in seasoned talent.
– Gradually introduce newcomers to ease the audience into a redesigned universe.
– Combine legacy appeal with renewed excitement.

Moreover, including Arabella Stanton in both the audiobooks and live-action establishes a rare continuity—one that resonates across different media and offers experiential cohesion. (en.wikipedia.org)
