Netflix Greenlights Documentary Detailing the Making of the Final Season of Stranger Things

Streaming giant Netflix has officially confirmed the upcoming release of a feature-length documentary chronicling the intensive production process behind the concluding season of the beloved series, Stranger Things. Titled One Last Adventure: The Making of Stranger Things 5, this project aims to definitively put to rest any lingering fan speculation regarding the possibility of a ninth episode following the official wrap-up of Season Five.

The behind-the-scenes chronicle, helmed by director Martina Radwan—who previously directed the film Girls State—is slated for a worldwide debut on Monday, January 12, 2026. Reports indicate that Radwan spent an entire year embedded within the production environment. This intimate access promises audiences an unparalleled, exclusive look into the creation of the final chapter. Director Radwan expressed profound gratitude toward the series creators, the Duffer Brothers, for entrusting her with the opportunity to document what she called this “grand journey.”

The Duffer Brothers themselves cited inspiration for this documentary stemming from the extensive supplementary materials accompanying Peter Jackson’s Lord of the Rings trilogy. They recalled how, during their formative years growing up in Durham, North Carolina, viewing those bonus features illuminated the “real nuts and bolts” involved in constructing massive Hollywood productions. The Duffers emphasized a strong desire to revive the tradition of “behind-the-curtain” narratives that delve into the mechanics of filmmaking, a format they feel has largely vanished with the decline of physical media distribution.

This forthcoming film is set to showcase both the sheer scale of the production—including the intricate construction of the Upside Down sets and the execution of complex action sequences—alongside deeply personal moments. Viewers can anticipate witnessing the emotional farewells exchanged by the cast and crew as they concluded their decade-long saga. The fifth and final season, featuring key actors such as Winona Ryder, David Harbour, and Millie Bobby Brown, concluded its narrative run with the airing of its last installment on December 31, 2025.

The documentary’s premiere, scheduled for less than two weeks after the series finale, is strategically positioned as the definitive, final curtain call for the show. By providing this comprehensive look behind the curtain, Netflix is offering fans a chance to process the end of an era through the lens of its creation. This commitment to documenting the process mirrors the detailed storytelling that characterized the show itself, ensuring that the legacy extends beyond the final frame.

Radwan’s year-long immersion suggests a level of detail rarely afforded to documentary subjects, promising insights into the logistical challenges and creative compromises inherent in wrapping up such a globally significant television phenomenon. The documentary serves as both a tribute to the craft and a historical record of one of the most defining television series of the modern streaming age, providing context for the monumental effort required to bring the story of Hawkins to a satisfying close.
