The leaks just don't seem to stop! Just a day after multiple teaser clips from Marvel’s highly anticipated ‘Avengers: Doomsday’ were leaked online, another major Phase 6 title has reportedly fallen victim to piracy and leaks. The first trailer for ‘Spider-Man: Brand New Day’, marking Tom Holland’s return as the friendly neighbourhood hero, has been widely shared online, months before its official release.

According to details circulating online, the leaked ‘Spider-Man: Brand New Day’ trailer was filmed while playing on a desktop. While some portions of the clip appear blacked out, the audio plays clearly. In the video, Tom appears to re-introduce himself as Peter Parker, thus picking up the story after the events of 'Spider-Man: No Way Home'.

Sadie Sink's role in 'Spider-Man: Brand New Day'

The video also seems to introduce Sadie Sink in a seemingly villainous role. In one of the most widely shared moments, her character warns 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 state that this could mean the actress will take on a villainous roles, others seem convinced that she will play Jean Grey, thus taking on the role of the mutant in the upcoming 'X-Men' film.
