Sadie Sink confirmed for Spider-Man: Brand New Day

A recently leaked image from the set of Spider-Man: Brand New Day shows actress Sadie Sink in costume, with fans believing the picture confirms who she plays in the film. However, the image has not yet been officially released by Marvel.

The leaks and the insiders

The image includes a Gemini logo in the corner, presumably because the original low-quality image was upscaled. Despite the lack of official confirmation, fans seem to have little doubt about the image’s authenticity. Marvel insider AlexfromCC claims the image is genuine and matches earlier descriptions of the character’s costume.

The Spider-Man: Brand New Day trailer also offers brief glimpses of a character who is likely Sadie Sink. This includes a figure wearing a large dark green jacket with a lighter hood. The same details were previously seen when Sink was photographed in public.

Sadie Sink’s role

While there were rumors that Sink would play a traditional Spider-Man villain, the latest confirmations suggest she may portray the iconic X-Men character Jean Grey. That would mean Sink may not be playing a standard villain in the film, given the complexity of Jean Grey. Several Marvel insiders have recently backed this theory as well.

Sink is also set to appear in the upcoming film Avengers: Secret Wars, scheduled for 2027. This points to a larger role for her within the Marvel Cinematic Universe. It seems Marvel may be preparing a reboot of the X-Men, with Jean Grey playing a key part.

Conclusion

The mystery surrounding Sadie Sink’s role continues. During an appearance on The Tonight Show Starring Jimmy Fallon, she said it feels like "torture" to be unable to reveal anything about her character. Maybe more will be revealed when Spider-Man: Brand New Day hits theaters on July 31, 2026.
