David Harbour has dropped out of an upcoming movie in the wake of the “Stranger Things” finale.
The actor, 50, will no longer star in Tony Gilroy’s drama film “Behemoth!” alongside Pedro Pascal, Olivia Wilde and Matthew Lillard, Searchlight Pictures confirmed to Variety on Tuesday.
Insiders familiar with the project told Variety that Harbour was overwhelmed by the end of “Stranger Things” — which aired its series finale on Dec. 31 — and stepped away from the movie to rest.
Harbour’s role has reportedly been recast, but the new actor’s identity is still unknown.
The Post has reached out to Harbour’s rep and Searchlight Pictures for comment.
“Behemoth!”, according to IMDb, “follows a musician from a family of musicians who returns to Los Angeles. A love letter to the music of the movies and the people who make it.”
Gilroy, best known for his work on the “Bourne Identity” movies and the “Star Wars” series “Andor,” wrote the script and is directing the movie. He’s also producing alongside Sanne Wohlenberg and his brother, John Gilroy.
Harbour’s exit from “Behemoth!” comes after he finished his five-season, ten-year run as Jim Hopper on “Stranger Things.”
The actor, who was diagnosed with bipolar disorder at 26 years old, was in the headlines throughout most of the press tour for the show’s final season.
On Dec. 18, Harbour dropped out of the “Stranger Things: The Final Season Celebration” event at the Paley Center in New York City, where he was set to appear on the red carpet with his co-stars and then participate in a screening and conversation.
A Paley Center spokesperson said Harbour would “not be present due to a scheduling conflict.”
A day earlier, TMZ reported that the “Thunderbolts*” actor was accused of stealing a fan’s hat during a bizarre incident at an Encinitas, Calif. bar.
Video surveillance reportedly showed that Harbour entered the venue and then ran back outside a few moments later with a white hat in his hand. He then looked over his shoulder and yelled, “C’mon, dude! F–king get me!”
The customer reportedly got his hat back from Harbour, and no physical altercation occurred between the two.
In November, a report surfaced that Harbour was accused of bullying and harassing his “Stranger Things” co-star Millie Bobby Brown.
But a few days later, the actors put on a united front at the Netflix show’s Season 5 premiere.
Harbour has also been dealing with the fallout of his divorce from singer Lily Allen, who implied the actor cheated on her in her latest album, “West End Girl,” released in October.
The Daily Mail reported that Natalie Tippett was Harbour’s alleged mistress, which Tippett has denied.
Harbour played coy about his and Allen’s split during an April 2025 interview with GQ Hype.
“I’m protective of the people and the reality of my life. There’s no use in that form of engaging [with rumors] because it’s all based on hysterical hyperbole,” he said.
Harbour added that he didn’t want to encourage “a salacious s–t show of humiliation.”
