As a new book in the iconic series was released every few years or so, and the film adaptations began, Harry Potter was everywhere. But now, the Harry Potter series is embarking on a brand new adaptation in the audio medium. Kit Harington as Jon Snow, Iwan Rheon as Ramsay Bolton in Game of Thrones. Also, as we previously reported, Game of Thrones alum Mark Addy had been cast in the audio series as Hagrid. If all goes according to plan, fans should have the full series by May 12, 2026, when Harry Potter and the Deathly Hallows is currently set for release.
