four “Avengers: Doomsday” previews released during the initial four weeks of “Avatar 3’s” cinema debut. Following this, we witnessed the inaugural preview for “Spider-Man: Brand New Day” on social platforms, the alternate MCU film slated for release next year. Sony will not unveil the preview before “Avatar: Fire and Ash” this week, but speculation suggests the film will be attached to “Anaconda,” scheduled to hit cinemas on December 26. If these speculations hold true, audiences will have the opportunity to view two separate trailers for the significant MCU crossovers set to debut next year.
After the initial “Doomsday” preview was leaked online, some questioned whether the footage had been created using AI. A similar scenario unfolded with the first “Brand New Day” preview. The latter was of even poorer quality than the first “Doomsday” footage, but at least the sound appeared sufficiently clear. In both instances, Marvel insiders who regularly divulge MCU information on social media asserted that the videos were authentic. Moreover, in both situations, the videos were taken down from the internet through copyright claims, which indicated that the trailers were indeed genuine.
Holy moly the leaked Spider-Man: Brand New Day trailer is authentic đź’€

In light of the MCU schedule for 2026, the timing of the first “Brand New Day” trailer release is even more logical than anticipating a teaser for “Doomsday” in theaters at this moment.
