The Duffer Brothers are concluding their work on "Stranger Things" with a final season expected in 2026. They have signed a new four-year deal with Paramount but will continue their commitments with Netflix through their banner, Upside Down Pictures. Two new supernatural projects are in development: "The Boroughs," featuring elderly heroes fighting an otherworldly threat in a retirement community, and "Something Very Bad Is Going to Happen," a horror-drama about a couple's wedding week.
