Overview

• The behind-the-scenes special, which debuted Sunday on HBO Max and HBO, confirms the new child leads and shows expansive sets like the Great Hall and Diagon Alley.
• HBO reiterates the format of eight-episode seasons for each J.K. Rowling novel, with Season 1 arriving at Christmas 2026.
