From short films to Netflix’s most talked-about sci-fi series, Martie Blair has emerged as a name to watch.

Let’s explore who Martie Blair is, how she landed this role, what makes her performance special, and what the future might hold for this rising star.
Who Is Martie Blair?
Martie Marie Blair (born March 24, 2012) is an American actress whose early work laid the foundation for a standout role in Stranger Things. She has been active since 2018 and has appeared in several short films before breaking into more widely known TV shows.

The Role of Young Eleven – A Closer Look
What Did the Role Involve?
Playing Young Eleven (the younger version of Millie Bobby Brown’s character) required more than just memorizing lines. Blair had to perform in scenes reflecting trauma, fear, and loss—elements at the core of Eleven’s identity. But there was also a technical twist: much of Young Eleven’s face in the show was CGI, modeled after Millie Bobby Brown when she was younger. Martie acted on-set, often wearing tracking markers and dots to help the visual effects team map Millie’s younger face onto her performance.

This hybrid performance demanded emotional maturity from someone so young, as well as precision—matching the physicality and mannerisms of Millie’s portrayal, but from a child’s perspective.
Working With the Cast & the Creative Team
One of the most interesting real-life elements of Blair’s journey is how collaborative the process was. Millie Bobby Brown reportedly worked closely with Martie, coaching her—teaching breathing techniques and guiding expression to ensure consistency with the older Eleven. Directors, effects artists, and other cast members also supported her in capturing a believable version of Young Eleven.
Martie has also spoken about her experience on-set: what it meant to see herself onscreen—partially transformed by CGI—and how she handled acting scenes that demanded both vulnerability and presence.
Real-Life Impact & Why It Resonates
A Young Actress on a Big Stage
For many child actors, moving from short films and smaller roles to a show like Stranger Things is a huge leap. Martie’s performance has resonated both with fans and critics because she handled this leap with a level of poise that’s rare for someone her age. It’s one thing to play in scenes that are emotionally taxing; another to do so under the scrutiny of CGI, fan expectations, and massive production values. Her ability to deliver in those conditions is a sign of talent and professionalism.
Audience Reactions & Case Study in Fan Reflection
Fans were surprised at how convincingly Young Eleven was portrayed—not just in resisting overuse of CGI, but in emotional beats. Many felt real empathy for Young Eleven’s storyline. That’s a sign of successful acting, especially in a show with many supernatural and sci-fi elements that risk disconnecting from humanity.

What’s Next for Martie Blair?
While Stranger Things is her mainstream breakthrough, Martie Blair’s early career suggests she could continue branching out. Here are a few likely paths:
