David Harbour to sit out 'Stranger Things' event after bizzare behaviour

David Harbour won’t attend the upcoming Stranger Things finale event in the wake of the reports of his erratic behavior.

The actor, 50, was slated to attend Stranger Things: The Final Season Celebration — an event at the Paley Center in New York City on Thursday, held on December 18

Following a recent incident, a Paley Center spokesperson said that Harbour will "not be present due to a scheduling conflict."

The actor, who plays beloved cop Hopper is no longer listed as an expected attendee on the red carpet. He is also not on the list of the actors doing screening and conversation on the venue's website.

This comes after Harbour took a man’s hat when he went to a gastropub in Encinitas. According to TMZ, he was seen leaving with the hat when the man followed him out and took it back, asking, "what the f--- did I do to you."

Millie Bobby Brown is also not attending due to a recent injury. The rest of the young group, including Finn Wolfhard, Gaten Matarazzo, Noah Schnapp, Caleb McLaughlin, as well as Maya Hawke are set to attend.
