Millie Bobby Brown allegedly filed a complaint with Netflix over the behavior of her co-star, David Harbour.The past few weeks have been rife with controversy for Harbour. Following their divorce, former wife Lily Allen made several critical comments about Harbour – who’s most famous for playing Hawkins chief of police Jim Hopper in Stranger Things – in her latest album, “West End Girl.” This includes claims that he is a sex addict, engaged in repeated infidelity, and undermined her successes.Credit: NetflixIn the wake of the album’s release, Harbour is reportedly “furious.” As a source told Heat, “The embarrassment is off the charts and he’s having a very hard time with it. He’s furious at essentially being accused of being this skirt chasing ‘monster’ and the world’s worst husband, so of course he’s telling everyone that he doesn’t deserve this.”Now, more fuel has been added to the internet’s anti-Harbour fire.Daily Mail reports that a formal complaint was previously made against Harbour on the set of Stranger Things by none other than Millie Bobby Brown, who plays his onscreen adopted daughter, Eleven.Complaint Made Against David HarbourAccording to the Daily Mail, Millie Bobby Brown filed a formal complaint with Netflix, alleging that her co-star, David Harbour, bullied and harassed her.Credit: NetflixThe report states that the complaint was lodged “before they started shooting the last season” of Stranger Things, and included “pages and pages of accusations.” This triggered an internal inquiry, which continued for months.While the details are unclear, the article makes clear that the allegations did not include any claims of sexual impropriety. Brown went on to have a personal representative by her side during the filming of the show’s final episodes – which, considering the closeness of the duo’s characters, likely included plenty of shared screentime.Allen reportedly stayed by Harbour’s side throughout the investigation into his on-set behaviour.Credit: NetflixBrown’s representatives declined to comment on the matter. The actress tied the knot last year, with only two Stranger Things cast members confirmed to be in attendance – Matthew Modine, who plays Dr. Martin Brenner (AKA Papa) and officiated the ceremony, and Noah Schnapp, who plays Will Byers and is Brown’s real-life best friend. Brown also welcomed her first child via adoption earlier in 2025.Netflix remains equally quiet on the matter.As a source told the Daily Mail, “Netflix will never comment on an internal investigation, but the fact they’ve not denied it speaks volumes. Stranger Things helped put Netflix on the map. Millions of fans around the world have been anticipating the finale. No one wants anything to take attention away from that.”Why It MattersCredit: NetflixFor Netflix and the show’s creators, the timing could not be more delicate. The fifth and final season of Stranger Things will debut its first volume later this month, followed by a second release over the holidays and a feature-length finale on New Year’s Eve — premiering simultaneously in theaters.Expected to become one of the platform’s most-watched titles to date, the series’s closing chapter now faces the challenge of separating its on-screen triumph from off-screen turbulence.Fans have already noted that Harbour seems largely absent from promotion of Stranger Things‘ final season, while the likes of Finn Wolfhard (Mike Wheeler), Sadie Sink (Max Mayfield), Gaten Matarazzo (Dustin Henderson), and Caleb McLaughlin (Lucas Sinclair) have already appeared in social media or television appearances to discuss the show.What do you think of the latest headlines on David Harbour?The post Millie Bobby Brown Files Official Complaint Against ‘Stranger Things’ Co-Star, Update Given appeared first on Inside the Magic.
