'Spider-Man: Brand New Day' trailer LEAKED after 'Avengers: Doomsday'; Sadie Sink’s villain goes up against Tom Holland

A trailer for 'Spider-Man: Brand New Day,' starring Tom Holland, has surfaced online well ahead of its scheduled 2026 release. This leak comes on the heels of similar incidents involving 'Avengers: Doomsday' footage. The leaked trailer, reportedly filmed off a desktop screen, offers a glimpse of Sadie Sink potentially portraying a villainous character, and hints at Peter Parker grappling with his powers.

Sony's response to the leak has been swift, with copyright takedowns initiated across social media platforms. This immediate action suggests the leaked footage is authentic, raising the possibility that Sony might be compelled to release an official trailer sooner than planned.

Trailer Details

Details circulating online suggest the 'Spider-Man: Brand New Day' trailer was recorded while playing on a desktop. Despite some obscured portions, the audio is clear. The trailer seemingly features Tom Holland re-introducing himself as Peter Parker, indicating the film picks up after the events of 'Spider-Man: No Way Home'.

Sadie Sink's Role

The leaked footage also provides a first look at Sadie Sink in what appears to be a villainous role. One widely shared clip features her character warning Peter Parker, saying, “You're a mess, Spider-Man. Don't get in my way. Otherwise, it won't just be your friends who don't remember who Peter Parker is.” While some believe this confirms a villainous role for the actress, others speculate she might be playing Jean Grey, a mutant character from the 'X-Men' franchise.

Other Characters and Plot Hints

The trailer reportedly includes scenes of Peter Parker struggling to control his abilities, including a sequence where he finds himself trapped in a web-like cocoon. Other teases include the Red Ninja clan, Boomerang as an antagonist, and appearances by Mark Ruffalo as Bruce Banner/Hulk and Jon Bernthal as the Punisher.
