Netflix Unveils Stranger Things Documentary — Release Date, Behind-the-Scenes Footage & Cast Interviews Revealed

Stranger Things fans won’t have to wait long for fresh content: the feature-length documentary “One Last Adventure: The Making of Stranger Things Season 5” lands on Netflix worldwide this Monday, 12 January 2026. The behind-the-scenes film pulls back the curtain on a decade of Demogorgons, from first auditions to the very last take, and streams at 3 a.m. ET/12 a.m. PT, so night-owls (or residents of the Upside Down) can press play the moment it drops. Directed by award-winning documentarian Martina Radwan (Girls State), the 100-minute film shadows the Duffer Brothers, cast and crew throughout the final season’s marathon shoot. Expect intimate interviews with Millie Bobby Brown, Finn Wolfhard, Noah Schnapp, Sadie Sink and series veterans who grew up on set, plus never-before-seen table reads, VFX tests and tearful good-byes as Hawkins closes its doors for good. Key moments teased in the newly released trailer include: • Matt and Ross Duffer swapping stories about the behind-the-scenes films for The Lord of the Rings that first inspired them to make movies—and to document the process. • Raw footage of the practical effects team building Vecna’s final form, complete with full-body prosthetics that took seven hours to apply each day. • A side-by-side flashback reel showing Gaten Matarazzo and Caleb McLaughlin filming their first bike-ride scene in 2015 and their last in 2025, underscoring just how far the young cast has come. Search traffic is already spiking for queries like “Stranger Things documentary release time,” “how to watch Stranger Things behind the scenes,” and “Making of Stranger Things Season 5,” so Netflix appears poised for another Top-10 takeover. If past companion docs such as “Beyond Stranger Things” are any guide, expect Easter-egg revelations, stunt secrets and playlist drops that will keep TikTok and Reddit sleuths busy long after the end credits roll. How to watch: 1. Open Netflix at (or after) 3 a.m. ET on 12 January. 2. Search “One Last Adventure” or navigate to the Stranger Things hub—Netflix will surface the documentary alongside the series. 3. For optimal nostalgia, consider re-watching Season 5 first; the doc references pivotal finale scenes, including Dustin’s graduation speech and that jaw-dropping Upside Down set-piece. With the flagship series officially wrapped, “One Last Adventure” serves as both a love letter to fans and a masterclass in blockbuster TV production. Plug in your Christmas lights one more time and prepare to go back to Hawkins—this time through the lens of the people who built it.
