Greta Gerwig’s Narnia Movie Snags Andor Star in Surprise Casting

An Andor standout is swapping blasters for lampposts, joining Greta Gerwig’s Netflix-bound Narnia film, due next year and widely believed to adapt The Magician’s Nephew.

Greta Gerwig's Narnia keeps adding interesting faces. The latest? An Andor standout is headed to the land before the wardrobe.

Denise Gough is in Gerwig's Narnia

On the 'We're Not Kidding with Mehdi & Friends' podcast, Denise Gough confirmed she's joining the cast of Gerwig's Netflix-backed Narnia movie.

"I'm doing a film with Greta Gerwig called Narnia. I'm playing someone mean in that, but it's fine, it's to children, it's okay."

No character name yet. If you're thinking Jadis, don't lock that in — nothing is confirmed beyond 'someone mean.'

So which book are we getting?

The project is widely believed to be The Magician's Nephew — the origin-story prequel that shows how Narnia comes to be. Emma Mackey and Carey Mulligan are already aboard, and if this is indeed Nephew, expect more 'how the world started' than 'kids stumble through a wardrobe.'

Quick refresher, in plain English: two friends set off on a desperate mission that flings them into other worlds, where an ambitious sorceress has plans for power. Then a lion named Aslan literally sings a new land into existence — the Narnia we know — where the rules of reality get flexible.

Release plan: a Netflix movie with an IMAX pit stop

This is one of those inside-baseball wrinkles: before it hits streaming, the film is getting a two-week theatrical run in IMAX in November 2026. It then lands on Netflix in December 2026. A limited big-screen window for a Netflix title makes sense for a world-builder like Narnia — and for Gerwig — but it's still a fun curveball.

Who is Denise Gough?

You probably know her as Dedra Meero, the icy ISB fearmonger in Andor. Beyond that, she's stacked her resume with TV like Titanic: Blood and Steel, Stella, Guerrilla, Under the Banner of Heaven, Who Is Erin Carter?, and The Stolen Girl. Films include Ridley Scott's 2010 Robin Hood, Juliet, Naked (2018), The Kid Who Would Be King (2019), and 2025's H Is for Hawk.

A quick Narnia refresher

The original film trilogy — The Lion, the Witch and the Wardrobe (2005), Prince Caspian (2008), and The Voyage of the Dawn Treader (2010) — pulled in nearly $1.6 billion worldwide. That run featured William Moseley, Anna Popplewell, Skandar Keynes, Georgie Henley, Liam Neeson, Tilda Swinton, James McAvoy, Ben Barnes, Peter Dinklage, and Will Poulter.
