From the moment Stranger Things season one debuted on Netflix, the sci-fi series was a hit amongst viewers. The show went on to have four seasons—with a fifth and final season confirmed by The Duffer Brothers—but one of the show’s stars didn’t think it wouldn’t make it past season one.
While appearing on BBC’s The One Show, actor David Harbour recalled the moment he thought the Netflix series wouldn’t get renewed for a second season. “I remember when we were shooting the first season. We were down in Atlanta, Netflix had given us a budget of about $20,” he said, according to the AV Club.
