According to The Hollywood Reporter, Netflix’s Stranger Things star David Harbour (Black Widow) gave some insight into the final season and teased the final episode. The actor spoke about the series during Thursday’s Happy Sad Confused podcast’s 10-year anniversary celebration at New York Comic Con. The podcast included conversations with host Josh Horowitz (Junketeer), Jack Quaid (The Boys), Zoë Chao (The Afterparty) and Jaimie Alexander (Thor).

While on stage, Harbour teased the upcoming fifth and final season of the series. “Look, I’m very close to the show, so I have very strong opinions, and they may not match yours if you’re a fan of the show,” he began via People. “I’m an actor on the show. So I see the nuts and bolts,” adding that he can sometimes be very critical of it and “get very mad” at “a bad episode” or a season he “didn’t like.”

As per The Hollywood Reporter, Harbour states he has no complaints on the eighth and final episode of the series. “They land the plane, and it is the best episode they’ve ever done,” he said before going deeper into an anecdote from the day the cast did the final table read.

“The end of this episode when we were reading it — just us reading it — about halfway through, people started crying,” Harbour recalled. “Then about the last 20 minutes, it was just uncontrollably crying, waves of different people. Noah Schnapp being my favorite.”

According to The Hollywood Reporter, Harbour explained why the cast became so emotional, and it was because, for many of the cast of Stranger Things, this was their childhood. When the series started, Millie Bobby Brown (Enola Holmes) and Noah Schnapp (Abe) were 11, Finn Wolfhard (It) was 12, Gaten Matarazzo (Foul Play) was 13 and Caleb McLaughlin (Concrete Cowboys) was 14. Now, each of them is in their 20s, almost a decade since the series premiere.

“It’s 10 years later, and we examine that idea, and it’s so well done and so beautiful,” he said. “It’s such a great episode, and it’s such a great season. You guys will love it.”

Stranger Things is available to stream on Netflix.
