The fourth instalment of Netflix’s fantasy hit was released earlier this summer in two volumes.
Though the new episodes have been incredibly successful, Harbour, who plays police chief Jim Hopper on the hit Netflix series, has admitted that he had doubts about the show at the start.
“I remember when we were shooting the first season,” the actor continued. “We were down in Atlanta, Netflix had given us a budget of about $20.
“Halfway through I remember my hair person coming up to me, like about episode four we were shooting, and she was like, ‘I don’t think it’s gonna work.’”
As the shoot continued, Harbour only became more pessimistic about the show’s chances.
“By the time we finished, we wrapped, I thought we wouldn’t get a second season; we’d be the first Netflix show kind of ever to never get a second season.”
The series from brothers Matt and Ross Duffer premiered in 2016 and is set to end after its fifth season, which has yet to be filmed.
The brothers have said very little about what’s in store, confirming only that the last season will feature a “time jump” to address the ages of the actors who play the kids on the show.
