Hans Zimmer is scoring HBO's Harry Potter and won't touch John Williams's themes: 'I would try to stay away as far as possible'
Expect the Harry Potter TV show to stray from the films’ familiar sound — there’s a major switch-up your ears will clock straight away.
Time to face the music—literally—if you’re gearing up for HBO’s Harry Potter TV remake. You’re not getting the John Williams magic you know from the films. Instead, the job of conjuring up fresh wizarding soundscapes has gone to Hans Zimmer. He’s got no plans of simply lifting the originals. In fact, if you’re expecting those familiar notes soaring over Hogwarts in this new outing, prepare yourself for something different.
Zimmer explained to Collider, 'I can't write like John Williams, but even if I could, I would try to stay away as far as possible and try to be original. So, does that sort of answer your question?'
Zimmer’s not going solo, either. He’s putting the new score together alongside Kara Talve and Anže Rozman—both from Bleeding Fingers Music. The idea is to give the series its own flavour, pushing the sound in a new direction for a generation who might not care about those old brass flourishes.
The Harry Potter series is aiming for a Christmas 2026 release on HBO.
Fresh Blood Behind the Curtain
Soundtrack aside, HBO aren’t skimping anywhere else. Francesca Gardiner (showrunner and executive producer) is running this ship, while Mark Mylod is executive producing and will direct more than one episode. It’s about as prestige as telly gets these days.

The cast is about as far from the film crowd as you can go. Dominic McLaughlin has nabbed the title role, with Arabella Stanton as Hermione, and Alastair Stout as Ron. You’ll spot John Lithgow stepping up as Dumbledore, Janet McTeer as McGonagall, Paapa Essiedu as Snape, and Nick Frost as Hagrid. Quite the shuffle, and not a Daniel Radcliffe in sight.
The Long Haul Adaptation
HBO are pitching this as a proper, all-in, seven-book adaptation. That means we’re not getting the films’ lightning-speed plots, but what they’re calling a faithful retelling. There’s a proper bonus for hardcore fans here: more space for the actual story.
- Season one is set for eight hours of screen time just for the first book
- Characters and details skipped by the films will finally be on screen—including Peeves the Poltergeist, who never surfaced on film
Gardiner and Mylod seem dead set on taking their time, exploring corners that the movies zipped straight past. The wider point: this is no retread. You’ll get familiar moments, sure, but with new faces, more scenes, and Zimmer’s original tunes blaring in the background.
