Millie Bobby Brown Reflects on a Missed Marvel Opportunity

July 03, 2026 – Before becoming a global star through Stranger Things, Millie Bobby Brown came close to joining another major franchise. The actress recently shared that she auditioned for the role of X-23, also known as Laura Kinney, in 2017’s Logan alongside Hugh Jackman.

Brown made the revelation while appearing in a game of “Lie Detector” with her Enola Holmes 3 co-star Louis Partridge. During the conversation, she admitted that she screen-tested for the role when she was just 11 or 12 years old.

She Screen-Tested With Hugh Jackman

Brown explained that the audition process went beyond a standard casting call. She recalled performing scenes opposite Hugh Jackman during the screen test, making the opportunity even more memorable.

Despite feeling excited about the role, Brown said she sensed she would not be cast. Looking back, she admitted the experience left her feeling “broken” after learning she had missed out on the part.

The Role Eventually Went to Dafne Keen

The part of Laura Kinney ultimately went to Dafne Keen, whose performance in Logan received widespread praise from both critics and audiences.

Keen’s portrayal introduced X-23 to the big screen and became one of the film’s standout performances. She later reprised the character in Marvel Studios’ Deadpool & Wolverine, bringing Laura Kinney back into the spotlight years after her acclaimed debut.

Missing Logan Didn’t Slow Her Career

Although losing the role was disappointing, Brown’s career quickly took off in another direction. Around the same period, she gained worldwide recognition as Eleven in Netflix’s hit series Stranger Things.

The success of the sci-fi drama turned Brown into one of Hollywood’s biggest young stars. She later expanded her résumé with leading roles in the Enola Holmes films, Godzilla: King of the Monsters, Godzilla vs. Kong, Damsel, and The Electric State.

Why the X-23 Role Was So Significant

When Logan premiered in 2017, it marked Hugh Jackman’s final outing as Wolverine after nearly two decades in the role. The film introduced Laura Kinney, also known as X-23, as a young mutant whose relationship with Logan became the emotional heart of the story.

The character quickly became a fan favorite, making the casting decision especially significant. While Millie Bobby Brown came close to landing the role, Dafne Keen’s performance ultimately helped establish X-23 as one of the most memorable new characters in the X-Men universe.

What This Reveals About Hollywood Casting

Brown’s revelation offers a rare glimpse into Hollywood’s highly competitive casting process. Even actors who go on to achieve international success often audition for major roles that ultimately go to someone else.

Stories like this highlight how casting decisions can shape careers in unexpected ways. While Brown missed the opportunity to play X-23, the experience became part of her journey before she found worldwide fame, proving that one unsuccessful audition doesn’t define an actor’s future.

Could Millie Bobby Brown Join Marvel in the Future?

Although Brown didn’t land the role of X-23, many fans believe a Marvel debut could still be in her future. Over the years, her name has frequently surfaced in fan casting discussions for various Marvel characters, thanks to her versatility and growing experience in blockbuster films.

Neither Brown nor Marvel Studios has confirmed any future collaboration. However, with the Marvel Cinematic Universe continuing to introduce new heroes and storylines, many viewers remain hopeful that she will eventually become part of the franchise.

Dafne Keen’s X-23 Continues to Shine

Dafne Keen’s portrayal of Laura Kinney was widely praised for capturing the character’s emotional depth and fierce determination. Her chemistry with Hugh Jackman became one of Logan‘s defining strengths, helping the film earn critical acclaim as one of the best superhero movies ever made.

Keen’s return in Deadpool & Wolverine also reignited interest in X-23, introducing the character to a new generation of Marvel fans. Her comeback demonstrated the lasting popularity of the role that Brown once hoped to play.
