David Harbour Faces Controversy After Accusations by Millie Bobby Brown (Report)

David Harbour, known for his role as Red Guardian in the Marvel Cinematic Universe (MCU), is facing allegations from his co-star, Millie Bobby Brown. This controversy has arisen just ahead of the highly anticipated release of Stranger Things Season 5 on November 26, 2025.

Controversy Details

Reports initially surfaced through the Daily Mail, revealing that Brown filed a complaint against Harbour prior to the filming of the fifth season. The detailed complaint, which reportedly contained “pages and pages” of accusations, does not include any sexual allegations. However, it did lead to an extensive internal investigation that lasted several months.

Brown was reportedly accompanied by a representative during the commencement of filming. Netflix has chosen not to comment on the situation as the investigation remains ongoing.

Relationship Dynamics

David Harbour and Millie Bobby Brown have been co-stars since the show’s debut in 2016. Their on-screen relationship explores a father-daughter dynamic, a bond that Harbour has previously described as protective and affectionate. He expressed deep concern for Brown, highlighting the challenges she faces with fame.

In a past interview, Brown referred to Harbour and fellow co-star Winona Ryder as parental figures, recalling moments when Harbour would caution her about personal matters. This close relationship makes the current controversy particularly poignant for fans.

Future of Stranger Things and MCU Roles

Stranger Things Season 5 is set to make history with its release schedule. The first four episodes will debut on November 26, 2025, followed by three episodes on Christmas Day, and the finale on December 31, 2025.
