David Harbour Emerges in Rare Reunion With 'Stranger Things' Costars After 'Harassment and Bullying' Claims

David Harbour reunited with the cast of Stranger Things for two events held Thursday, May 21, after nearly seven months of skipping appearances with them.

The actor, 51, turned up at the SAG-AFTRA Foundation Conversations Presents Stranger Things in Los Angeles before moving on to Netflix's Stranger Things Emmys FYSEE event at Hollywood Forever Cemetery.

Castmates Natalia Dyer, Jamie Campbell Bower and Noah Schnapp joined Harbour at both events.

Meanwhile, Millie Bobby Brown, who played his adopted daughter in the 1980s-themed coming-of-age sci-fi series, did not participate in either event.

Other cast members missing from the May 21 events were Maya Hawke, Winona Ryder, Finn Wolfhard, Gaten Matarazzo, Caleb McLaughlin, Sadie Sink, Charlie Heaton, Joe Keery and Brett Gelman.

Harbour last attended the show's November 2025 premiere, but missed a series finale event and its press tour.

The Netflix series aired 2016-2025.

Brown reportedly filed a “harassment and bullying” claim against Harbour in January 2024, before filming Season 5.

"There were pages and pages of accusations," a source told Daily Mail. "The investigation went on for months."

However, the claims supposedly did not include any allegations of sexual misconduct.

According to the legal documents, the British actress requested a “personal representative” to be present during scenes filmed with Harbour. The actor was allegedly investigated internally.

Still, Harbour and Brown seemingly put the rumors to rest while doing press for Stranger Things Season 5 in November 2025, praising each other in interviews and posing sweetly together for photos.

“We’ve been doing that for the last 10 years,” Brown said of their bond on the red carpet. “I mean, we have always been united in that. We love this show with everything, and we value our friendship more than anything.”

She described reuniting with Harbour for Season 5 as "so nice" and "really exciting."

“Of course I felt safe," Brown said in a clip shared on Deadline's TikTok in November 2025. "I mean, we've worked together for 10 years. I feel safe with everyone on that set."

She continued, "We also play father and daughter so naturally, we have a closer bond than the rest because we have had some really intense scenes together, especially in Season 2. David and I have a great relationship. We work really closely together in the scenes and preparing for the scenes and I really am excited to see … for everyone to see the labor of love and hard work we’ve put into the closure of our relationship and what that looks like.”

Harbour married singer Lily Allen in 2020, and the couple split in 2025.

Her 2025 album, West End Girl, detailed their marital demise.

"Some of it is based on truth and some of it is fantasy," Allen told CBS Mornings in November 2025.

About the demise of his marriage, Harbour told British GQ in March 2025, "I'm protective of the people and the reality of my life. There's no use in that form of engaging [with tabloid news] because it's all based on hysterical hyperbole."

He has opened up about facing alcoholism and bipolar disorder.

"My mental health disorder is something I live with, but it does not define me," he told Future of Personal Health. "However, if it defines you, I can assure you that there is a way to have a tremendously fulfilling life."

He continued, "I'm living proof that you can be anything you want to be. There were times when I thought I'd never get to do what I wanted to do in this world or that I'd never get off the couch, frankly, and I want people to know that it does get better."
