Stranger Things Writers Faced Script Uncertainty During Filming

The documentary highlights that the writers were uncertain about the narrative's direction while filming with an incomplete script.

The brothers had to shoot scenes with a 'summertime look' during the summer without a finished script—a challenge Matt Duffer described as 'the most difficult writing circumstances we’ve ever found ourselves in.'

Matt Duffer claimed that Eleven was initially going to kill herself, but later stated, 'We think she's made the choice to live. Just kidding, she hasn't.'

Ross Duffer stated that the entire episode had to build toward the idea that 'Eleven is going to kill herself,' and that the show's ending was intentionally ambiguous to let viewers decide her fate.

Montana Maniscalco noted that they were shooting episode 8 before it was completely written, adding, 'spoiler alert!'

Matt Duffer admitted he had never read episode 8 all the way through while they were shooting it, describing the process as 'so weird jumping to eight... Don’t love it.'

The 'Conformity Gate' theory, circulating among fans on TikTok, suggests the final episode was a deception conjured by Vecna to manipulate Mike Wheeler and his friends into believing they had triumphed over evil.

Some fans also claimed a secret ninth episode with an alternate ending exists, with one asserting it would be released on January 7.

Another fan argued the Demogorgon was scarier as a solo entity, sparking debate across the fandom.

Jamie Campbell Bower dismissed speculation about alternative endings and extra scenes, stating that the two-plus-hour finale, titled ‘The Rightside Up,’ revealed the fates of both the villainous Vecna and the heroes who confronted him.

The show's fourth season became its most popular, briefly holding the record as Netflix’s most-watched English-language series before being surpassed by Wednesday.
