Behind the scenes: voices from the set

Martina Radwan tells Tudum she felt privileged to spend a year documenting the production. She praised the Duffers and the long-time collaborators who welcomed her and shared candid moments from a decade of filmmaking. Radwan said the experience was “pure joy” and noted she wished she could have documented Seasons 1–4 as well.

The Duffer Brothers on the documentary

Matt and Ross Duffer said they were inspired by classic behind-the-scenes films like The Lord of the Rings documentaries and wanted to revive that kind of production storytelling. They describe One Last Adventure as a return to on-the-ground filmmaking that shows the nuts and bolts of a large-scale series and a tribute to the people who made the show possible.

What fans can expect

The trailer teases pivotal final-season moments and emotional goodbyes — including the Duffers addressing cast and crew. Expect interviews, on-set footage, rehearsal clips and technical breakdowns that reveal how key sequences were made. The film aims to honor both the creative process and the personal connections forged over five seasons.
