Netflix is set to release "One Last Adventure: The Making of Stranger Things 5," a behind-the-scenes documentary chronicling the creation of the final season of the hit series. The documentary, directed by Martina Radwan, will be available on the streaming platform on January 12, 2026. It promises an intimate and emotional look at the efforts behind the series' conclusion.

The final season of "Stranger Things" concluded on December 31, 2025, marking the end of a decade-long journey for the cast and crew. The documentary offers fans one last chance to delve into the world of Hawkins and say goodbye to the characters they've grown to love.

The trailer for "One Last Adventure" reveals glimpses of the emotional table reads, the creative process of the Duffer brothers, and the cast's reactions to the ending of the show. Ross Duffer reflects on the difficulty of writing the characters' final lines, while Matt Duffer recalls the impact of typing "End Series". The trailer also teases a "debate over Eleven's fate,".

Radwan, who spent a year on set, expressed her gratitude for the opportunity to witness the making of the final season. She noted the Duffer brothers' ability to push boundaries and inspire those around them. The Duffer Brothers themselves have stated that they were inspired by the behind-the-scenes documentaries for "The Lord of the Rings" and wanted to bring that kind of storytelling back.

"One Last Adventure" aims to capture the scale of effort, the pressure, and the emotional weight of concluding a story that has defined a generation of viewers. It explores the challenges of crafting the final season, from the writers' room to the last day of filming. The documentary also highlights the cast's journey of growing up in Hawkins and the creative team's revisiting of the story's origins.

The documentary is expected to not only appeal to "Stranger Things" fans but also to those interested in the behind-the-scenes workings of a major Hollywood production. Netflix is providing a "front-row seat" to the making of the final season. With the series finale having been released on December 31st, the documentary will be available on January 12th.
