Millie Bobby Brown cries reading emotional speech on 'Stranger Things' final season set

Millie Bobby Brown is graduating from the Upside Down.

On Friday, the "Stranger Things" star, 20, shared an emotional clip of herself choking up while reading a goodbye speech on the set of the hit Netflix show's final season.

"Isn't graduation supposed to bring relief, like you're glad to leave behind the teachers and classmates? Not me," she said in the video posted on Instagram. "I am nowhere near ready to leave you guys."

She added, "I love each and every one of you, and I'll forever carry the memories and bonds we've created together as a family. I love you. Thank you."

Brown shared the video at the end of a carousel of photos of herself taken throughout her years on "Stranger Things," going back to the first season in 2016.

Like her co-stars, the actress has grown up working on the sci-fi series, and she was 12 when the first episodes hit Netflix. She has since starred in movies like "Enola Holmes" and married Jake Bongiovi, son of Jon Bon Jovi. Her "Stranger Things" co-star Matthew Modine, who plays Papa, officiated the wedding earlier this year.

Brown's post came as Netflix on Friday confirmed "Stranger Things" has finished production on its final season. "THAT'S A WRAP ON STRANGER THINGS," read a post from Netflix's official X account.

In his own Instagram post, Brown's co-star Finn Wolfhard said he was "still in shock" that the show is ending and posted a photo of himself and his co-stars on the set when they were younger.

"We shot (the final season) for a year and I'll miss all of my friends and our characters terribly," he wrote. "When I think of the show, I picture this first photo. A bunch of goofy young people making something they think is cool but really have no clue what's to come. I feel like we're still those people and I’m lucky to still stand beside them today."

Noah Schnapp, meanwhile, wrote on Instagram that he was feeling "very emotional" about the end of the series.

"As I close this chapter of my life, I can't help but be forever grateful for the incredible people that I’ve met and valuable life/career lessons I learned through this decade journey," he said.

In an interview with Josh Horowitz at New York Comic Con in October, David Harbour teased that the "Stranger Things" writers "land the plane" in the series finale, which he described as the best episode of the entire show. He also recalled the cast all getting emotional while reading the script.

"About halfway through, people started crying, and then (during) about the last 20 minutes, it was just uncontrollable crying, waves of different people," he said.

"Part of that also is the fact that these kids, it was their childhood," he added. "They started the show when they were 11 and 12, and here we are reading and it's nine, 10 years later, and we examine that idea (in the show). It's so well done and so beautiful."

Netflix hasn't confirmed a premiere date for "Stranger Things" Season 5, but it will debut in 2025.
