Millie Bobby Brown files harassment, bullying complaint vs 'Stranger Things' co-star David Harbour—report

Stranger Things actress Millie Bobby Brown has reportedly sued her co-star David Harbour.

According to the Daily Mail, the 21-year-old allegedly filed a harassment and bullying claim against the Thunderbolts* actor, 50, before they started shooting the last season

A source claimed that there were "pages and pages of accusations,” and that Harbour faced an internal investigation that "went on for months."

There were no allegations of misconduct of a sexual nature, as per the report. The Enola Holmes stars also allegedly had a representative on set for season 5, which finished filming in December 2024.

Representatives for Netflix, Brown, and Harbour have yet to respond to the alleged complaint.

In Stranger Things, Brown plays Eleven, a girl with psychokinetic and telepathic powers, while Harbour plays Hawkins chief of police Jim Hopper, who eventually adopts her.

The Electric State actress, in 2018, shared that she and Harbour would bicker like a real dad and child. This was before season 3 was released in July 2018, which saw Hopper intervening with Eleven's relationship with Mike.

"We went through so many different emotions... We get angry at each other, we are like father and daughter," she said during Paleyfast, as per Refinery29. "We got angry at each other, we would express our feelings on and off the set, and... those scenes were so raw and real that the reward is the scenes."

For his part, Harbour called their relationship "special" as he first met her when she was a kid in 2016.

"I have a real protective feeling for her. I have a real, like worry. I worry about her and the fame and all that she has to struggle with. And I've just always felt this kind of deep fatherly affection for her," he said on the That Scene with Dan Patrick podcast in July 2021.

The alleged complaint comes as Harbour's ex-wife, Lily Allen, released her latest album, West End Girl, partly inspired by the breakdown of their relationship. 

The fifth season of Stranger Things is set to hit Netflix in three parts: Volume 1 on Nov. 26, Volume 2 on Dec. 5, and the finale on Dec. 31.
