Audible’s upcoming full-cast adaptation of J.K. Rowling’s Harry Potter series just got a magical boost. Two fan-favorite stars from HBO’s Game of Thrones—Kit Harington and Iwan Rheon—have officially joined the voice cast, bringing their talents to the wizarding world in a groundbreaking audio experience set to launch November 4, 2025.
Quick read:
- Kit Harington voices Lockhart in Audible’s Harry Potter series.
- Iwan Rheon plays Professor Lupin.
- It’s a full-cast, immersive audiobook experience.
Kit Harington Cast as Gilderoy Lockhart
Known globally for his brooding portrayal of Jon Snow, Kit Harington will take on the flamboyant and self-absorbed Professor Gilderoy Lockhart. This casting choice adds a layer of intrigue, as Harington’s dramatic gravitas contrasts sharply with Lockhart’s comedic vanity. Fans can expect a fresh interpretation of the character, blending charm and satire in a way only Harington can deliver. His performance will debut in Harry Potter and the Chamber of Secrets, the second installment of the series, releasing December 16, 2025.

Iwan Rheon to Voice Professor Lupin
Iwan Rheon, infamous for his chilling role as Ramsay Bolton, will voice the beloved Professor Remus Lupin. This marks a dramatic shift from villainy to vulnerability, as Lupin is one of the most compassionate and complex characters in the Harry Potter universe. Rheon’s nuanced voice work promises to capture Lupin’s quiet strength and tragic depth, especially in Harry Potter and the Prisoner of Azkaban, arriving January 13, 2026.
With immersive Dolby Atmos sound design and a cast of over 200 actors, Audible’s Harry Potter: The Full-Cast Audio Editions is poised to redefine audiobook storytelling. Fans of both franchises are in for a spellbinding treat as Westeros meets Hogwarts in this epic crossover of fantasy worlds.
