Sadie Sink landed Spider-Man: Brand New Day without an audition—and didn’t even read the script

Here we go again with the wild game of 'Who On Earth Is Sadie Sink Playing?' in the new Spider-Man: Brand New Day film. If you haven’t been keeping up, this is the next big superhero outing from Sony and Marvel, and it’s got everyone guessing – and probably a fair few people at Marvel Studios quietly laughing behind closed doors.

Sadie Sink’s Mystery Role

Sadie Sink – yes, her off Stranger Things and that David Fincher/Zach Cregger Netflix horror game (she’s everywhere) – is joining the spider-circus with Tom Holland, Zendaya, and Jacob Batalon. Now, the elephant in the room: who, exactly, is she playing?

Honestly, no one’s managed to pin this down yet. The rumour mill is working overtime, especially with folks online convinced Sink is bringing Jean Grey to the MCU. That’s mostly because fans have spotted her on set toggling between outfits: sometimes dressed like a low-rent Punisher, other times sporting an oversized coat with the hood up, all very cloak and dagger. Truth is, it’s all guesswork. The secrecy is so locked down that not even Sadie herself knew her part when she signed on.

No Audition, No Script – Welcome to Marvel

Here’s where it gets properly odd: Sink literally didn’t audition for the role. Not even a chemistry test over Zoom – nothing. The story, as dug up by Nylon, is that she was just offered the part thanks to her past work with director Destin Daniel Cretton (they previously did The Glass Castle together back in 2017). It gets better – or worse, depending on your trust issues – she wasn’t given a script until she landed in London for filming. Sink put it this way:

'Sometimes even she wasn’t privy to the details [of her Marvel role]: Sink was offered her role without an audition, having worked with director Destin Daniel Cretton on the 2017 film "The Glass Castle," and she didn’t receive a script until she landed in London.'

That’s Marvel for you – show up and hope for the best.

Sadie’s Crash Course in Superhero Fandom

If you’re wondering whether Sink was ready to jump into the MCU baggage train, she’s been pretty candid. In her chat with Nylon, she admitted:

'I knew that Marvel was a big deal and had a big brand, especially Spider-Man. I know there’s a huge fan base, but it feels really big. I think these blockbuster movies are a whole different beast.'

Fair to say, being in a Netflix horror game is one thing, but the MCU has its own unique level of madness.

Tom Holland: Your Friendly Neighbourhood Tour Guide

Joining the world’s most scrutinised film franchise can’t be a relaxing experience for anyone, but at least Sink had Tom Holland by her side – who’s now basically the Spider-Man supervisor for Marvel new recruits. According to Sink, Holland was as chilled out as anyone could hope for, welcoming her into the 'outsider' club, making sure she wasn’t left feeling like the last kid picked in PE.

In her words, Holland 'could not have been more welcoming,' and the whole crew made her feel at ease. Always helps when you’ve got a lead actor who’s not taking himself too seriously.

In Summary: The Theories Continue

• Sadie Sink is confirmed for Spider-Man: Brand New Day; who she’s playing is entirely up for speculation, with Jean Grey as the leading theory.
• Sink didn’t audition and didn’t get her script until filming in London started.
• The film’s out 31 July, and it’s entirely plausible audiences won’t know her character’s identity until opening night.
• Director: Destin Daniel Cretton (linked to Sink via The Glass Castle).
• Sink’s been frank about being stunned by Marvel’s scale, but Tom Holland helped her settle in quickly.
