Who is Screwball? Everything to Know About Sadie Sink's Rumored Character in 'Spider-Man: Brand New Day'

Published 03/18/2026, 4:33 AM EDT

The next chapter in the Marvel Cinematic Universe is building anticipation, with Spider-Man: Brand New Day shaping up to be a major turning point for Peter Parker. After the reset in Spider-Man: No Way Home, the film promises a fresh start, with Peter living anonymously and dealing with more grounded, street-level challenges in New York. This shift opens the door for new characters, fresh threats, and storylines that reflect the modern world in ways the franchise has not explored much before.

As Marvel leans into this “back-to-basics” approach, fans are especially curious about which villains or anti-heroes could define this new era, especially with Sadie Sink's name circling the web. While some speculate about major comic book heavyweights, others believe the film may spotlight lesser-known but thematically relevant characters. And that is where one intriguing name keeps surfacing in fan discussions: Screwball. 

A new kind of villain, one shaped by the internet age, could redefine Spider-Man’s challenges in this chapter.

All about Screwball Marvel’s livestreaming supervillain

Among Spider-Man’s more unconventional adversaries, Screwball stands out as a distinctly modern creation. Introduced in The Amazing Spider-Man #559 by Dan Slott and Marcos Martín, she is not defined by superpowers or grand schemes. Instead, Screwball operates as a livestreaming criminal, an attention-hungry performance artist who turns crime into content. Whether she is orchestrating rooftop chases or pulling off flashy heists, everything she does is broadcast for an audience, blurring the line between entertainment and danger. 

Narcissistic, energetic, and unpredictable, Screwball thrives on chaos and public validation. Her skill set: parkour, acrobatics, and tech-savviness, makes her a frustrating opponent for Spider-Man, especially in high-speed urban environments. While she may not pose the existential threat of villains like Green Goblin or Venom, her presence adds a different kind of tension, one rooted in unpredictability and spectacle.

Adding fuel to the speculation is Sadie Sink, whose casting in Spider-Man: Brand New Day has sparked widespread curiosity. Best known for her emotionally layered performances, Sink brings a mix of intensity and charisma that fans believe could elevate Screwball beyond a comedic nuisance.

While Marvel has kept her role under wraps, the idea of her portraying a chaotic, media-savvy antagonist has gained traction, especially given the film’s “fresh start” narrative and focus on a younger, more grounded world.

A tonal shift in Spider-Man’s world is already becoming evident through early glimpses and creative changes behind the scenes.

A darker tone and a new direction for Spider-Man’s return

The first glimpse of Tom Holland back in action suggests that Spider-Man: Brand New Day would not just be a narrative reset, it may also be a tonal shift. Early footage teases a more somber, almost introspective vibe, with Spider-Man swinging through the city in slow motion while a voice ominously hints at rebirth. It is a stark contrast to the high-energy spectacle of previous entries and signals a more mature phase for the character.

This installment also marks a major behind-the-scenes change, with Destin Daniel Cretton stepping in as director, replacing Jon Watts. Known for his work on Shang-Chi and the Legend of the Ten Rings, Destin Daniel Cretton brings a different storytelling sensibility, one that could blend emotional depth with grounded action. The film’s visual tone, combined with its street-level focus, suggests a Spider-Man story that prioritizes character and atmosphere over multiversal chaos.

It is also worth noting that this is Tom Holland’s first solo outing as Spider-Man since the massive success of No Way Home, which redefined the franchise by bringing together multiple generations of the character. Now, Brand New Day appears to be doing the opposite, stripping things back and rebuilding from scratch. A new suit, a new status quo, and potentially a new kind of villain all point toward a reinvention designed to keep the series fresh.
