David Harbour breaks silence on Lily Allen album and his mental health struggles

David Harbour has opened up about his mental health, his separation from Lily Allen, and the emotional aftermath of Stranger Things in a candid new interview with Variety.

The actor, known globally for playing Jim Hopper in Stranger Things, said the end of the Netflix series marked a turning point in his life and career. While he acknowledged the show brought him fame and recognition, he also admitted feeling the weight of public attention and personal struggles, including a mental health breakdown.

Harbour, 51, shared that he has long dealt with bipolar disorder and described recent challenges as overwhelming. He said that while he values privacy, public speculation around his personal life — including the release of Allen’s album West End Girl — added to a difficult period for him.

Allen’s album, which drew widespread attention for its alleged references to their relationship, intensified media scrutiny. Harbour, however, avoided directly addressing the claims, stating that he respects artists using personal experience in their work while maintaining boundaries around his own private life.

Professionally, Harbour is moving forward with new projects, including HBO’s DTF St. Louis, where he plays Floyd Smernitch, an emotionally complex suburban interpreter. He described the role as a return to deep character work, allowing him to explore vulnerability and emotional nuance beyond his Stranger Things fame.

He also reflected on the impact of long-term fame, saying that public perception often reduces actors to “objects” rather than people. Despite this, Harbour said he remains focused on creating meaningful work that connects with audiences.

As he transitions into a new phase of his career, Harbour said he hopes his performances continue to offer comfort and relatability. “I want to make things that make people feel like they’re not alone,” he added.
