A new documentary about the making of "Stranger Things" Season 5 includes some surprising behind-the-scenes revelations.

New Stranger Things documentary casts doubt on Conformity Gate theory, showing no signs of a secret ending or hidden messages.

The theory centers on the idea that the brilliant writing present in the first four seasons was largely the work of Ross Duffer's ex-wife, Leigh Janiak. Janiak is an American screenwriter and director, as well as the creator of the Fear Street franchise. The pair were together from December 2015 to February 2024.

Stranger Things 5 had 237 days of filming and 6,725 setups. The main unit alone captured 630 hours of footage occupying a petabyte (1,000 terabytes) of data. Imagine storing that in 1987.

The doc, called One Last Adventure: The Making of Stranger Things 5, included behind-the-scenes clips of creators, executive producers and writers, Ross and Matt Duffer, joined by the other writers in the team as they debated exactly how their treasured 80s show should come to an end.

The behind-the-scenes doc 'One Last Adventure', highlighting the epic final season, is now streaming on Netflix.
