Behind the Scenes: A ‘Very Irresponsible’ Day on Stranger Things

During the Stranger Things season 5 premiere event, David Harbour revealed that while he usually prides himself on being professional and focused during filming, there was one particular scene in season 3 that tested his composure.

The scene in question involved Harbour’s character, Hopper, sitting on a bed with Millie Bobby Brown’s Eleven and Finn Wolfhard’s Mike. Harbour recalled angrily telling Mike to leave the room because he didn’t want him in bed with his daughter, delivering the line, “You got to get home.” However, when Mike asked, “Why? What’s the matter?” Harbour responded with, “It’s your grandma,” a line that unexpectedly made him break character repeatedly.

Harbour explained to PEOPLE, “For some reason, that particular line, I couldn’t say it for like an hour. I laughed and laughed to the point where the children, Millie and Finn, were like, ‘What is wrong with you? We need to get to work.’” Despite the disruption, the moment became one of Harbour’s favorite memories from the set, illustrating the genuine chemistry and fun the cast shared behind the scenes.
