Avengers Doomsday Teaser Release Date – When to Expect It in 2025

As of now, Avengers: Doomsday might be one of the biggest projects Marvel has produced, and it is finally a wrap for the filming crew.
The only movie that can beat the scale of Avengers: Doomsday is possibly Avengers: Secret Wars. And we would have no complaint about that.
With some of the OG Avengers, the X-Men, Fantastic Four and the young Avengers joining the film, at this point, fans have lost count of how many more of their favourite Marvel characters will make their appearance in the movie.
With Robert Downey Jr returning to the MCU as the infamous Doctor Doom and the star-studded cast alone would’ve ramped up the film’s budget.
Marvel does have a lot riding on this film, and even though there are many leaks and rumours about what the plot will be, Marvel always has a way of keeping us on our toes when it comes to the Avengers.
The shooting of Doomsday began back in April 2025 and lasted 5 months, as the crew wrapped up last Friday, September 18, 2025.
But you cannot get excited already because if Infinity War and Endgame were any indication, it will take a minimum of 4 months before we get a teaser.
We can only expect full-scale promotion of the film after Spider-Man: Brand New Day, which is set to premiere on July 31, 2026.
The film will go into 14 months of post-production and will be released in December 2026. But the promotions have already begun on a minor scale as Doctor Doom’s light show hit Shanghai last week.
