A new report out of the U.K. claims Stranger Things star Millie Bobby Brown filed a harassment and bullying complaint against her co-star David Harbour before the start of the show’s final season — a claim Netflix has not confirmed, and one that comes entirely from The Mail on Sunday’s reporting.
The story has ignited controversy online, with a post about the allegations on X being hit with a Community Note pointing out that the original claim relies on anonymous sourcing tied to a friend of Harbour’s estranged wife.

However, because this involves two of Netflix’s most recognizable stars (and one of Marvel’s major stars in the post-Endgame era) and lands just weeks before Stranger Things returns, the entertainment world is paying attention.
The allegations stem from The Mail on Sunday, which reported that Brown submitted “pages and pages” of concerns and that Netflix internally investigated. The paper emphasized that none of the claims involved sexual misconduct.

Representatives for Brown, Harbour, and Netflix did not comment, according to reporting from Page Six and TV Insider.
Netflix, consistent with its usual approach to internal matters, has issued no confirmation that any review took place.
What the Mail Reported
The Mail quotes an anonymous source saying: “Millie Bobby Brown filed a harassment and bullying claim before they started shooting the last season… There were pages and pages of accusations. The investigation went on for months.”
The source further alleged: “Netflix will never comment on an internal investigation, but the fact they’ve not denied it speaks volumes.”

The Mail also reported Brown had a personal representative on-set during filming of the final season.
X Community Note Raises Red Flag
A post spreading the allegation on X was quickly flagged by Community Notes with this message: “The only source quoted is a friend of Mr. Harbour’s estranged wife, described from the article: A friend of Ms Allen’s — whose new album eviscerates Mr Harbour claiming he cheated on her multiple times — said:”

That note is verified and emphasizes that this story relies not on neutral production insiders, but on a social circle tied to Harbour’s recent marriage split.
Context: Lily Allen’s Album and Public Scrutiny
The story also arrives as Harbour’s marriage to singer Lily Allen has entered headlines. Her new album, released October 24th, features lyrics many believe reference infidelity and emotional turmoil.

In an interview with The Sunday Times, Allen noted: “I don’t think I could say it’s all true — I have artistic license… But yes, there are definitely things I experienced within my relationship that have ended up on this album.”
This backdrop makes the sourcing chain all the more delicate — one reason social media users and fact-checkers are treating the report carefully.
Past Comments Resurface
Harbour has spoken publicly about caring for Brown earlier in their careers. In a People-sourced interview, he once said of his young co-star: “I try to protect her as much as I can.”
That quote is now being revisited in light of the claims.
What We Can Say Responsibly
Here is the reality as of now:
- The Mail on Sunday reported Brown filed a harassment and bullying complaint.
- Page Six and TV Insider repeated the report.
- Netflix has not confirmed any investigation.
- All allegations are based on anonymous sourcing.
- X has flagged the story’s origin as tied to a friend of Harbour’s estranged wife.
- Neither Brown nor Harbour has spoken about the claims.
This remains a developing situation in which verified transparency from primary parties is currently absent.

With Stranger Things Season 5 Part 1 premiering November 26th, the pressure surrounding the show and its stars is intense — and the timing alone guarantees this story will continue to circulate.
Until there is on-record confirmation or denial from Netflix or the actors involved, the only responsible approach is to report what is known, scrutinize the sourcing, and avoid speculation.

Harbour definitely seems like a male feminist creep and he deserves this likely false allegation.
