Doing It for the Art: A genre that only got a revitalization in The New '10s, a concept that requires some good coding chops to implement well, and a female lead that got them rejected at almost every publishing studio, plus a unique art style and hipster soundtrack? This has all the makings of an indie film, only it's a game, one that DONTNOD is most certainly not making for the fame and fortune.
Executive Meddling: Averted. DONTNOD said that several publishers they approached wanted them to change the lead to a male, but luckily Square Enix was the only one that didn't want them to change anything about the concept.
Mr. Jefferson earned himself the nickname of "Jeffershit" after turning out to be the Big Bad at the end of Episode 4.
Bae or Bay, the decision which is the last ever in the game where you choose to either let Chloe die in the first place or leave Arcadia Bay to be wrecked near the lighthouse at the very beginning, while in front of the storm.
Missing Trailer Scene: Episode 4's trailer had Nathan shout "The storm is coming! You're all gonna die!" Not only is this line not in the game, there's nothing in the game that indicates that Nathan was ever aware of the storm.
Playing Against Type: Ashly Burch usually voices characters that are all-the-way comedic, but this time, she voiced a Troubled, but Cute girl who has gone through a lot of misery in her life, which became one of her best performances in her career.
The E3 trailer shows at the end that you can rewind after focusing into a picture. A downplayed example, as it only covers the first three episodes and follows their official release rather than preceding it.
Episode 5's launch trailer spoils that the tornado comes from Max's powers.
In the files for Episode 3, there is a confrontation between Mr. Jefferson and Max, probably intended for after Chloe angrily drops Max off. However, the developers decided to have Max silently exit Chloe's car, followed by an immediate transition to her room.
Also from the Episode 3 files, Chloe's rant was originally supposed to end with her saying, "Max, if I had your power, I would go all the way back and change everything! Everything!" The line was most likely removed because it would have been Five-Second Foreshadowing to what was about to happen.
Episode 3 was originally going to include a scene where a man wearing a suit and gloves examines the red binders. The scene was most likely removed because the figure's build matches Mr. Jefferson's and the developers didn't want to give away the twist.
Unused audio files from the confrontation with Nathan in Episode 4 show Nathan hinting at an oncoming "storm", suggesting that he knows about the storm in Max's vision. Interestingly, Nathan saying, "the storm is coming! You're all gonna die!" was included in the trailer, but didn't make it into the game. As revealed in a spoilercast, Nathan was originally intended to have had a vision of the storm. However, this wouldn't have gone anywhere, so they cut it.
One idea during development was that Max would have been caught red-handed while euthanising Chloe in Episode 4, resulting in her arrest and a Non-Standard Game Over.
Unused audio files indicate that William was going to be one of the characters stalking Max in the labyrinth. He would have yelled at Max for killing him and for either killing Alt!Chloe or leaving her to suffer.
More unused audio files show that Rachel Amber would have appeared before Max in the Dark Room sequence and would have blamed her for her death.
During DONTNOD's charity livestream of Episode 5, the developers confirmed that the person that Rachel said changed her life right before she vanished and the person she was talking about in her letter to Chloe that Max can find in the junkyard in Episode 2 is Mr. Jefferson.
Word of Saint Paul: Ashly Burch, Chloe's voice actress, did an interview with FemHype where she provided some of her personal interpretations of Chloe's character. Among other things, Chloe's sexual orientation and gender identity are fluid and her love for Rachel was unrequited.
