New insights reveal more information about the situation between Millie Bobby Brown and David Harbour.
Recent headlines have zeroed in on David Harbour, fueled by Lily Allen’s album West End Girl. In the record, Allen levels claims of sex addiction, serial infidelity, and professional undercutting. Harbour, sources told Heat, is “furious” about the portrait—and struggling with the fallout.

“As a source told the outlet, “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.”
Millie Bobby Brown’s Complaint Against David Harbour
Amid that scrutiny, the Daily Mail reported that Millie Bobby Brown filed a formal complaint to Netflix, accusing Harbour of bullying and harassment. The filing reportedly predated Season 5 production, ran “pages and pages,” and prompted a months-long internal review.
The article specified no allegations of sexual misconduct. Brown, per the report, had a personal representative on set during filming.

Allen was said to remain supportive of Harbour during the process. Brown’s team didn’t comment on the story. Netflix also declined comment, with one source telling the outlet, “Netflix will never comment on an internal investigation, but the fact they’ve not denied it speaks volumes.”
Observers also noticed Harbour’s light presence in early Stranger Things marketing while other cast members surfaced in interviews and social hits.
On November 6, Harbour appeared upbeat at the Season 5 premiere in Los Angeles. He and Brown posed together, hugged, and took fan selfies. Both arrived in tandem and spoke warmly about each other on the carpet.

Brown told Entertainment Tonight: “I obviously had a really special bond with David… It’s been so special to have him along the journey for me.”
Harbour told ET – his sole media stop – “I adore her, and I’ve been proud to watch all of them grow up… we’ve gotten to know each other so deeply.”
Their friendly red-carpet dynamic came just days after the Daily Mail story dropped. Neither addressed the report directly, and Harbour kept press to a minimum.
Crisis Control Kicks In Amid ‘Stranger Things’ Premiere
Now, industry sources have shed more light on the situation to Variety.
Reportedly, Harbour wasn’t scheduled for heavy junket duty regardless, citing shoots for HBO’s DTF St. Louis and Marvel’s Avengers: Doomsday (2026), where he stars alongside his other onscreen daughter, Florence Pugh.

Crisis strategists framed the carpet plan as signaling unity. “The goal in these situations is to make it no worse,” one PR executive said.
Netflix amplified playful moments between the pair online. Florence by Mills liked a post with a heart emoji, and many fan comments downplayed any rift.
Variety reported that insiders confirmed an investigation into Brown’s complaint and that it was resolved. The actors share multiple Season 5 scenes; a Variety reporter observed one during a July 2024 set visit. Representatives for Brown, Harbour, and Netflix didn’t respond to requests for comment.

Asked broadly about set culture, the show’s creative leads emphasized safety and respect without naming parties.
Shawn Levy said, “The truth is that we view this crew and this cast as family, and so we treat each other with respect, and that’s always been bedrock.”
Ross Duffer added, “We’ve been doing this for 10 years… nothing matters more than just having a set where everyone feels safe and happy.”
Stranger Things closes with a staggered rollout, beginning later this month and culminating in a New Year’s Eve feature-length finale that will also air in movie theaters.
