Millie Bobby Brown and Chris Pratt face a robot uprising in “The Electric State.”

The 20-year-old who started playing the psychic powerhouse Eleven Stranger Things when she was just 11 herself, she said she drew on her own experiences trying appear hard, even if she didn't feel like it. “Technically we're both the same age, so I feel like it was just a question of: What are moments where I wouldn't show my weakness? What moments would I like to have? And I just played with it,” she says. “I really want her to show that she is made of stone because I want that to be the perception of who she is. But the better you get to know her, the softer and warmer she becomes. And I tried to put as many of my own experiences into it as possible.”

At this point The Electric StateIn the alternate history, humanity won the war, but still lost its way. Most people's lives are dominated by helmet-like digital devices that allow them to escape into a virtual fantasy land. Elsewhere, the banished robots struggle in a different direction, embittered by their lack of rights and desperate to prove their individuality and free will. They are led by… Mr. Peanut. Yes, the Planters mascot. He is a sentient device, once created for marketing purposes, who has evolved into a battle-weary elder statesman who leads his band of machine companions, most of whom were also designed to have cartoonish appearances but with real minds , emotions and a strong survival instinct.

Mr. Peanut is voiced by Woody Harrelson, and beneath the tough exterior lies a hint of a certain ex-president who famously grew up on a peanut farm in Georgia. “We gave Jimmy Carter a folksy vibe,” says Anthony Russo. The mechanized revolutionary also shares a tragic aspect with Carter, a one-term president who was admired for his thoughtfulness but has struggled to be effective in the past. “He almost has a bit of a history with Carter in the sense that he was more concerned with ideals than practicality and things didn't go as well as he had hoped,” says Joe Russo.
