Who Is Holly Wheeler? 4 Things to Know About the Season 5 'Stranger Things' Star

Stranger Things heads into its final chapter with a new addition to the cast stepping in as Holly Wheeler.

Nell Fisher, a 14-year-old British actress, plays the youngest member of the Wheeler family in the fifth and final season, succeeding Anniston and Tinsley Price.

"Holly Wheeler had been played for the first four seasons by Anniston and Tinsley Price, who did a wonderful job creating a character the fan base knows and loves," she told Tudum. "Holly's been important but on the periphery, and this season, Holly becomes a protagonist. Things start happening to her, and she starts getting things done. I'm really excited to be able to play this character."

She shared a similar sentiment with People, noting her predecessors "are really lovely girls."

Before joining the cast of Stranger Things, Fisher appeared in Evil Dead Rise and Choose Love.

Although the actress playing Holly has changed across the seasons of Stranger Things, the character herself has been present in the story since Season 1 as Ted and Karen's third child and Mike and Nancy's younger sister.

"She's in the Wheeler household, and the Wheelers and the Byers are living together. At first, Holly has this imaginary friend called Mr. Whatsit, who we later discover to be Henry [Jamie Campbell Bower]. She goes through a big journey this season, discovering this new, crazy supernatural world," Fisher said of her character.

Holly is often seen reading her favorite book, A Wrinkle in Time, which Fisher said became a big part of preparation "because Holly's been an important character who's kind of touched the surface of this weird supernatural world."

Fisher continued, "She uses A Wrinkle in Time to understand what's happening to her and to orient herself in this new crazy world. Henry is Mr. Whatsit, Henry's mind prison is Camazotz, and Vecna is IT."

In the first volume of Stranger Things Season 5, Vecna tricks Holly when he warns her about "monsters." He later sends a Demogorgon to kidnap her and take her to the Upside Down, where Holly discovers Max alive but trapped within Henry's memories.

The duo teams up in an attempt to take down Henry/Vecna after everything that has happened.

"I filmed it with Cara Buono, who plays my mother, and the Duffer brothers, and it was such a blast," Fisher said of filming the scene.

After years on the sidelines, Holly is now a key player in Stranger Things Season 5 as series creators Matt and Ross Duffer chose to mirror Will Byers' disappearance in Season 1.

"For this season, the Duffer Brothers wanted to centralize Holly as a main character. Many, many years ago, we had two 3-year-old twins play Holly, back when I was shooting her following Christmas lights down a hallway," said executive producer Shawn Levy. "So this time around, there was both an opportunity, but also a necessity, to find someone to play Holly who is around the same age — that innocent, defining age — that our kids were when this started."

By making Holly a larger role, Stranger Things earns "a new character to explore and root for."

Levy continued, "[It] is also very thematic because, in many ways, this show has always been about childhood, about the vulnerability of innocence, but also the superpower of innocence. We've all watched these kids grow up and have this very visceral connection to the kids of Stranger Things."
