Maya Hawke spoke up while filming the final season of Stranger Things. In the new Netflix documentary, One Last Adventure: The Making of Stranger Things 5, fans get a behind-the-scenes look at the season, and at one point, Hawke, 27, asks a pretty pivotal question to director Shawn Levy.

Stranger Things 5 production details revealed in the new documentary show a very difficult filming process. Matt and Ross Duffer admitted they started filming the series finale before the script was finished.

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 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.

When Martina Radwan, the director of the documentary “One Last Adventure: The Making of Stranger Things 5,” first met with Matt and Ross Duffer, the show’s creators, she told them that yes, she would want to celebrate the series by showing how the final season was made.

Stranger Things star Noah Schnapp (Will Byers) had an idea for the show's emotional final scene, and the Duffer Brothers ran with it.

The Making of Stranger Things 5," on Netflix Monday, is the streaming service's first full behind the scenes feature.
