Composer Hans Zimmer will create an original score for the upcoming HBO television adaptation of the Harry Potter books. The series is scheduled to debut at Christmas 2026.
Why it matters
Zimmer intends to compose entirely original music for the project to distinguish the new series from the iconic film scores previously composed by John Williams.
The production team has allocated eight hours of screen time to adapt the first book of the seven-volume series. This runtime allows for the inclusion of additional narrative details not featured in the films.
