Sworn to Secrecy! The Stranger Things Kids Can't Even Share Their Season 2 Scripts with Family

The highly anticipated season 2 of Stranger Things is six months away — and sorry to break it to you, Upside Down fans, but things are going to remain shrouded in secrecy for a while.

Stars Millie Bobby Brown, Finn Wolfhard, Noah Schnapp, Caleb McLaughlin and Gaten Matarazzo are on the cover of the May issue of emmy magazine (out May 17), and PEOPLE can reveal an exclusive First Look at their interview, in which they open up about their top-secret work on the upcoming season of the cult favorite Netflix series.

Filming takes place in Atlanta at Screen Gems Studios — and while it may be sunny and hot outside, it’s dark and quiet on set, where only hair and makeup and a few key crew-members are permitted.

“My brother always asks me, ‘Gate, can you send me the script?’ ” says Matazarro, 14. “I’m like, ‘It’s a new season, and it’s a lot stricter than last year ’cause he read them last year, but this year he’s not able to ’cause we don’t want any, like, hacking interference.”

United in their shared secrets, the five costars have grown exceptionally close — and Brown, 13, who describes herself as “a real girl’s girl in pink and pearls and rings and necklaces,” has found her way to fit in with the boys by taking up whiffle ball.

In particular, she and Schnapp, 12, have grown particularly close.

“Noah comes around almost every weekend for sleepovers,” she says. “We watch really scary movies on Netflix like The Babadook and Hush.”

In fact, watching movies was one of the ways the young actors initially prepared to take on their roles, with creators Ross and Matt Duffer assigning them a list of classics to watch, including E.T., The Goonies, Jaws and Poltergeist.

Schnapp also says his father helped school him on the mindset of the ’80s: “They were always outside,” says Schnapp. “It’s all phones and computers now.”

“You know, I kind of miss the ’80s. Even though I wasn’t alive,” he adds with a laugh.
