Ida Brooke Lands Huge Dune 3 Role: 5 Things to Know

When the cast list for Dune: Part Three started leaking out in bits and pieces, most of the headlines went exactly where you would expect – Timothee Chalamet returning, Zendaya back as Chani, Robert Pattinson joining the fold, Jason Momoa somehow returning from the dead as a ghola. All big names and all predictable chatter.

But one name sat quietly near the bottom of early reports and sent a very different kind of ripple through the internet: Ida Brooke.

Unless you would been following British independent film or keeping close tabs on Apple TV+’s Silo, the name probably didn’t register right away. So who is she? Where did she come from? And why should you care beyond the obvious “she’s in a massive movie” answer?

Here are five things worth knowing.

1. She’s Playing One of the Most Important Characters in the Entire Dune Saga

Let’s start with the role itself, because it matters.

Ghanima Atreides isn’t a side character. She is not someone’s love interest who shows up for three scenes and disappears. In Frank Herbert’s Dune Messiah, the novel that Dune: Part Three adapts, Ghanima is one of the twin children born to Paul Atreides and Chani. Her twin brother is Leto II. Together, they represent the next generation of the Atreides bloodline, and their births come at a devastating cost: Chani dies bringing them into the world.

The name Ghanima itself is Fremen for “spoil of war.” That’s not accidental. Herbert chose it to signal the price that Paul’s empire has extracted from everyone around him including the people he loves most. Ghanima carries the weight of that legacy from the moment she takes her first breath.

What makes the role particularly tricky for an actress is this: Ghanima is not just a baby in the lore. She has born pre-loaded with ancestral memories, centuries of genetic knowledge inherited from her parent’s bloodlines. She is aware, intelligent, and spiritually ancient from birth. That’s an enormously complex to portray, even in a film that may only introduce her in the final act.

And if Villeneuve’s franchise continues – Children of Dune is the next novel in the sequence – Ghanima becomes a full-blown protagonist. She’s politically shrewd, emotionally grounded, and serves as the human counterweight to her brother Leto II, who eventually transforms into something far less recognizable. She’s the one who stays human. That matters.

For Ida Brooke, this isn’t just a credit on a resume. It’s a doorway into a character that could define an entire phase of her career — if the franchise extends beyond the current trilogy.

2. She Already Has Real Credits and They’re More Interesting Than You’d Think

One of the first things people do when an unknown actor is cast in a huge franchise is check their IMDb page. With Ida Brooke, what you find there is compact but surprisingly telling.

Silo (Apple TV+) — Young Shirley Campbell

Her most recognizable role before Dune came in the Apple TV+ sci-fi series Silo, based on Hugh Howey’s dystopian novel series. Brooke played the younger version of Shirley Campbell, a key character in the show’s Mechanical department. The adult Shirley is played by Remmie Milner.

It’s the kind of role that doesn’t dominate screen time but demands precision. Young versions of established characters have to capture the essence of someone without mimicking them, you are not doing an impression, you’re building a foundation. Brooke handled it well enough that casting directors clearly took notice.

The Primrose Railway Children (2024) — Becks Robinson

Before the sci-fi work, Brooke appeared in The Primrose Railway Children, a family film that follows three siblings, Becks, Phoebe, and Perry Robinson as they’re uprooted from their life in Glasgow and dropped into a remote village in the Scottish Highlands. Brooke played Becks, one of the three kids navigating that transition.

It’s a completely different register from anything in the Dune universe. A gentle, character-driven film aimed at younger audiences. But that’s exactly the point, it shows range. She wasn’t chasing the same type of role over and over. She was working, learning, and building.

Behind the Camera — Stay on the Line

Here’s where things get genuinely interesting. Ida Brooke isn’t only an actress. She’s also a writer and director.

She wrote and directed a short film called Stay on the Line, which has been praised for its emotional depth and strong visual sense. She’s also directed commercial work, including an ad for Sasha Donovan. On top of that, she’s reportedly a film student, which means she’s approaching storytelling with a structured, academic understanding of how narrative and visual language interact.

That combination, acting in front of the camera while directing and writing behind it, is unusual for someone this early in their career. Most actors at her level are focused entirely on auditions and bookings. Brooke seems to be thinking about the craft from multiple angles simultaneously, which suggests a long-term vision for her career rather than a narrow pursuit of fame.

3. Her On-Screen Twin Is Nakoa-Wolf Momoa — and Their Casting Together Tells a Story

Ida Brooke wasn’t cast in isolation. She was paired with Nakoa-Wolf Momoa, the son of Jason Momoa, who plays her twin brother Leto II Atreides.

That pairing raised eyebrows for obvious reasons. Jason Momoa played Duncan Idaho in the first two Dune films and returns in Part Three as a ghola, a clone-like resurrection of the original character. Having his real-life son cast in the same film immediately triggered the “nepotism baby” discourse that haunts every second-generation casting in Hollywood.

Jason Momoa addressed it head-on. In public statements, he made clear that Nakoa-Wolf earned the role through auditions and on his own merit that no strings were pulled and no calls were made on his behalf. Whether you take that at face value is your business, but it’s worth noting that Denis Villeneuve is not a director known for making casting decisions based on favors. His track record suggests he casts the person who fits the role, full stop.

What’s more interesting, though, is what Ida Brooke’s casting says in this context. She has no famous parents. No industry connections that have been reported. She came up through British television, a children’s film, and independent short filmmaking. If Villeneuve was simply handing out roles based on connections, Brooke wouldn’t be in the picture. The fact that she and Nakoa-Wolf were cast together, through the same process, for the same film, suggests the director found a genuine dynamic between them.

Playing twins on screen is harder than most people realize. It’s not enough to look similar. You need to share a rhythm, an instinct, a way of occupying space that reads as lifelong familiarity. If Villeneuve saw that between Brooke and Momoa, it explains why both were locked in.

4. She’s Joining One of the Most Stacked Ensembles in Modern Cinema

Let’s talk about the company she’s keeping.

Dune: Part Three doesn’t just have a good cast, it has a cast that would make any director in the world jealous. Ida Brooke is stepping onto a set where she’ll be working alongside:

Timothée Chalamet as Paul Atreides
Zendaya as Chani
Rebecca Ferguson as Lady Jessica
Florence Pugh as Princess Irulan Corrino
Anya Taylor-Joy as Alia Atreides
Javier Bardem as Stilgar
Jason Momoa as Duncan Idaho (Hayt)
Robert Pattinson as Scytale
Charlotte Rampling as Gaius Helen Mohiam
Josh Brolin as Gurney Halleck
Isaach De Bankolé as Farok

That’s not a cast list. That’s a murderer’s row. Multiple Oscar nominees, global box-office stars, and some of the most respected character actors working today, all directed by Denis Villeneuve, who co-wrote the screenplay with Brian K. Vaughan (the creator of Saga and Y: The Last Man).

For a relatively unknown actress, this is either the opportunity of a lifetime or the most intimidating first day at work imaginable. Probably both.

What’s reassuring, if you’re rooting for Brooke, is that Villeneuve has a track record of elevating newcomers. He brought Timothée Chalamet into the franchise when Chalamet was still primarily known for indie dramas. He gave Zendaya meaningful dramatic material when she was still transitioning from Disney Channel origins. He’s a director who creates space for actors to grow into their roles rather than boxing them in.

Principal photography wrapped in November 2025, which means Brooke has already shot her scenes. Whatever performance she gave, it’s already in the can. Now it’s just a matter of waiting for December 18, 2026.

5. She Keeps a Low Profile and That Might Be Her Smartest Move Yet

In an industry where emerging actors are often advised to build their social media following before their filmography, Ida Brooke has taken a noticeably different approach. She’s kept her personal life private. Her exact age isn’t public knowledge. She doesn’t appear to be chasing viral moments or manufacturing an online persona.

For some actors, that kind of restraint would be a career risk. Visibility matters in Hollywood, and algorithms reward the people who feed them content. But for someone about to appear in a film that will generate its own tidal wave of publicity, staying quiet beforehand might be the smartest possible strategy.

Here’s why: when Dune: Part Three hits theaters, every entertainment outlet on the planet will be running profiles, interviews, and features on the cast. If Brooke has kept herself relatively unknown until that point, the discovery narrative writes itself. Audiences and journalists love finding someone new, someone who doesn’t already have a Wikipedia page that reads like a novel. The less that’s known about her beforehand, the more interesting the reveal.

The Bottom Line

Ida Brooke’s path to Dune: Part Three didn’t follow the typical playbook. There was no viral moment that launched her. No famous parent who opened the door. No blockbuster teen franchise that served as a stepping stone. Instead, there was a supporting role in a sci-fi streaming series, a children’s film shot in the Scottish Highlands, a self-directed short film, and apparently, an audition that convinced one of the most meticulous directors in the world that she could carry the weight of Ghanima Atreides.

That’s not a story about overnight success. It’s a story about preparation meeting opportunity at exactly the right moment.

Dune: Part Three arrives in theaters on December 18, 2026. When it does, Ida Brooke won’t be an unknown anymore. The only question is what she does with the attention.
