For nearly a decade, Stranger Things has been more than just a show — it’s been a cultural phenomenon. From its perfectly curated ’80s soundtrack to its intricately detailed plotlines, deeply human characters, and supernatural thrills, the series has inspired fan theories, endless online discussions, and a devotion that stretches far beyond the screen.

Now, as the Duffer Brothers bring the saga to a close with its fifth and final season, Netflix is inviting viewers behind the curtain for the first time. A new documentary, One Last Adventure: The Making of Stranger Things 5, promises to peel back the layers of the creative process, revealing the mammoth effort that went into crafting the show’s finale. Here's what you need to know about seeing the magic of Hawkins come to life in real time.

What is the Stranger Things documentary about?

The documentary, directed by Martina Radwan, follows the production of the final season over the course of a year. Radwan, best known for her Emmy-winning cinematography and her feature Tomorrow, Tomorrow, Tomorrow, captures candid moments from the writers’ room, the set, and the emotional table reads where actors say goodbye to characters they’ve grown alongside for years.

We'll get to see the cast reflecting on the journey of Eleven and the rest of the gang, the challenges of concluding a decade-long story, and the collaborative energy that fuels a production of this scale. It also offers rare insight into the Duffer Brothers’ creative process, their dedication to storytelling, and the countless decisions — big and small — that brought Hawkins to life.

When will it come out?

The documentary will premiere on January 12, 2026, giving fans a first look at the making of one of television’s most beloved finales. If you subscribe to the 'Conformity Gate' theory, that's just five days after the real Stranger Things finale is due to air...

Where can you watch it?

Naturally, One Last Adventure: The Making of Stranger Things 5 will be available exclusively on Netflix. Luckily, it will be streaming worldwide, so you can watch from wherever in the world you find yourself.
