Nell Fisher shares how Millie Bobby Brown got 'Stranger Things' cast grooving

Nell Fisher, who stars as Holly Wheeler in Stranger Things Season 5, shared an interesting behind-the-scenes moment that is still stuck in her head.

At the Los Angeles premiere of Stranger Things Season 5 on November 6, 14-year-old Fisher opened up exclusively to PEOPLE.

“During filming for episode eight, it was stressful, tiring, and tricky,” Fisher told the media outlet.

“Millie Bobby Brown took me and a bunch of other kids aside, and we all choreographed a dance to ‘Please, Please, Please’ by Sabrina Carpenter. I still remember it!”

Fisher, who joins the Wheeler family as Nancy and Mike’s younger sister, added with a laugh, “To this day, I think of it whenever the song comes on.”

To prepare for the role, Fisher met with Anniston and Tinsley Price, the twins who previously played Holly.

“We spent two hours at a trampoline park, and they’re really lovely girls,” she said, describing how the meet-up helped her to prepare for the character.

Additionally, she also formed a close friendship with Finn Wolfhard on set, who plays her brother Mike Wheeler.

“He’s such an amazing guy,” said Fisher.

“He’s been really helpful, kind of talking me through what’s to come since he was around my age when he started on the show.”
