Marvel Cinematic Universe fans received the ultimate holiday gift this week with leaked trailers for two massive 2026 tentpoles: “Avengers: Doomsday” and “Spider-Man: Brand New Day.” Marvel plans four “Doomsday” previews during “Avatar 3’s” opening weeks, while Sony’s “Brand New Day” teaser reportedly attaches to “Anaconda” on December 26. These authentic leaks—verified by insiders and swiftly copyright-struck—ignite hype for Spider-Man’s July 31 return and the Avengers’ December 18 epic, bridging four years since “No Way Home’s” $2 billion triumph.
Despite initial AI fakery skepticism, clear audio and rapid takedowns confirm legitimacy, per scoopers like Daniel Richtman. Spider-fans craving early glimpses face a scramble before theater exclusives hit.
Trailer Leak Timeline
Social media erupted with split “Brand New Day” clips, recapping “No Way Home’s” memory wipe while teasing new alliances. Sony’s strategy leverages “Anaconda’s” holiday draw, timing perfectly ahead of summer release. YouTube uploads follow screenings, though reshares vanish fast.
Brand New Day Plot Teasers
Tom Holland opens as a vulnerable Peter Parker confessing to an unseen confidant: “Hi, my name is Peter Parker. You don’t remember me, but we used to know each other.” He grapples with isolation post-spell, embracing “the hard thing, even if it breaks Peter Parker’s heart.”
The second half escalates: Hulk (Mark Ruffalo) encounters an incognito Spider-Man, suggesting desperate aid-seeking. Jon Bernthal’s Punisher dramatically intervenes, while Sadie Sink’s enigmatic anti-hero warns: “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.”
