Science fiction has long been a playground for imagination, but it’s also a launchpad for the next generation of stars. From fearless teen rebels to wide-eyed alien whisperers, young characters often carry the emotional weight of sci-fi narratives—and many of the actors behind them got their start long before they landed those breakout roles.
For families with children who dream of being in the next Stranger Things, A Quiet Place, or Obi-Wan Kenobi, the journey may begin in the most unexpected ways: local commercials, modeling gigs, or background roles. These smaller opportunities often set the stage for major roles in the worlds of aliens, androids, and alternate dimensions.
Here’s a look at some young actors who rose to sci-fi fame from humble beginnings—and how parents today can support their own aspiring stars with modern-day tools like online casting platforms.
Before she shaved her head and became Eleven, Millie Bobby Brown was just another talented kid attending auditions with her parents. She started out with small television appearances in shows like NCIS and Grey's Anatomy. But it was her role in Stranger Things—a supernatural sci-fi thriller that became a cultural phenomenon—that catapulted her into stardom.
What’s especially inspiring is that Millie’s parents weren’t industry insiders. Like many families, they simply followed her passion and supported her through a series of small roles that led to a major opportunity. Today, she’s not only a star but also a producer and a UNICEF Goodwill Ambassador—all before turning 20.
Jacob Tremblay’s breakout performance in the heart-wrenching drama Room won him critical acclaim, but it was his roles in sci-fi hits like Wonder and Doctor Sleep that showcased his versatility. Tremblay even voiced Flounder in Disney’s live-action The Little Mermaid and will soon appear in sci-fi-heavy projects.
Tremblay’s early years included commercials and smaller roles—many of which were discovered through open casting opportunities. His journey reminds us that early experiences in front of a camera, even if small, help children develop confidence, presence, and emotional range.
For parents today, platforms that connect aspiring young talent with children’s film auditions are a practical way to explore similar paths. These platforms make it easier to find roles that fit a child’s age, personality, and developmental stage—especially in niche genres like science fiction and fantasy.
When Logan hit theaters in 2017, audiences were blown away by the fierce energy of Dafne Keen as Laura/X-23. Just 11 years old at the time, Keen managed to hold her own opposite Hugh Jackman and Patrick Stewart—two titans of the X-Men franchise.
Before taking on that intense, emotionally complex role, Keen had only a handful of acting credits, mostly in Spanish TV. Her rise is a reminder that talent often shines brightest in bold genres like sci-fi, where young actors are asked to portray extraordinary emotions in extraordinary situations.
It also shows the importance of readiness. Many casting directors say they look for children who are adaptable, imaginative, and comfortable taking direction—skills that can be nurtured through early experiences in performance. Whether through stage classes, short films, or opportunities aimed at toddler models, these early experiences lay the groundwork for future roles.
Another Stranger Things alum, Finn Wolfhard’s journey into the sci-fi spotlight began with a self-taped audition for Mike Wheeler. Before that, he was mostly known through smaller acting gigs and his band, Calpurnia. His love of sci-fi and horror made him a perfect fit for roles in Ghostbusters: Afterlife and It, where he continued to embrace otherworldly adventures.
Wolfhard’s experience highlights the accessibility of today’s industry. With tools like self-tapes, virtual callbacks, and platforms that streamline teen casting, kids don’t have to live in Hollywood to be considered for big roles. What they do need is the chance to build experience, explore their interests, and show up authentically.
The actors above may be household names now, but their careers were built one role at a time—often beginning with modest projects, print work, or local productions. What they share is not just talent, but persistence, family support, and the willingness to take the first step, no matter how small.
Today, families don’t have to rely on industry connections or live near major studios to get started. Online platforms make it easy to explore roles that fit your child’s interests, whether they’re into superheroes, space sagas, or sci-fi thrillers.
Whether your child is dressing up like a robot or reenacting scenes from Star Wars, there may be more than just playtime in their future. With the right tools, encouragement, and opportunities, they might just follow in the footsteps of the young stars who turned their love of science fiction into full-blown careers.
Sci-fi will always have a place for dreamers—and that includes the youngest among us. From toddler sidekicks to teenage heroes, children play a critical role in bringing imagination to life on screen. With more casting opportunities available than ever before, there’s never been a better time to explore what’s out there.
If your child is showing interest in acting or modeling, consider starting small, staying safe, and having fun with it. You never know where one audition might lead—and in the world of sci-fi, anything is possible.
