Last month, Netflix announced Stranger Things season 3 had officially gone into production, and we've already started to hear a few details about what to expect. Over the weekend at a Netflix event called FYSee, Millie Bobby Brown gave hints about Eleven's arc in the forthcoming season and revealed she's hoping the series will see one particular big-name guest star in the future.

Brown wants Leonardo DiCaprio to join the cast in the future at some point, explaining that he'd be perfect to play "Eleven's long-lost brother." She also said she's got a storyline involved for him already, adding, "Leo, if you want to be in Stranger Things, here's the contract." David Harbour (Chief Jim Hopper) has hinted the third season won't arrive until 2019, so there's plenty of time.

DiCaprio, like Brown, was a child star, earning his first Oscar nom at 19 for What's Eating Gilbert Grape.

Speaking with Variety, Millie also teased some details for her character's future. "It's a beautiful storyline for Eleven this season," she said. "It's really a coming of age for her and understanding what being a normal teenage girl is."

Speaking about the show's creative team of The Duffer Brothers and producer Shawn Levy, she said, "The Duffer brothers and Shawn Levy and Netflix really know how to grow with the characters so it's very good. They know how to write us and how we're growing and our voices are changing and our mindsets are changing and we are maturing every day."
