The hype train for the next ultimate Marvel Cinematic Universe crossover event has officially left the station, and it's barreling ahead at full speed. Ever since San Diego Comic-Con shook the world with Robert Downey Jr.'s villainous return to the franchise, fans have been desperately scouring the internet for any shred of Doctor Doom footage.
Well, we finally have concrete, verified details on exactly when the public will get its first glorious look at the film, alongside an unexpectedly early confirmation regarding just how long we'll be sitting in theater seats.
When Is the Official Trailer for Avengers: Doomsday Expected to Drop?
Marvel Studios has locked in its highly anticipated return to the iconic Hall H stage at San Diego Comic-Con on Saturday, July 25, 2026. Multiple industry trade reports have confirmed that the studio plans to premiere the first official public teaser trailer during its presentation.
The trailer is rumored to show Doctor Doom on a throne in Latveria, where he lingers by a huge painting of what seems to be his wife and son.
The trailer would also supposedly show Thor and the Fantastic Four meeting the New Avengers to get acquainted. A Loki in a TVA suit is expected to join them in Steve's house at some point (the same house shown in Steve's trailer).
But the highly anticipated main scene of the teaser is Thor coming up against Doctor Doom, where the MCU's newest unstoppable giant controls the Sentinels and reportedly tells the God of Thunder, "One day, you will forgive me."
Fans will be glad to know that tickets go on sale on July 20, five months before the massive MCU event film arrives in theaters. However, tickets will only be made available for Infinity Vision theaters, as the studios previously indicated that it would only be shown in select theaters.
How Long Is Avengers: Doomsday's Current Runtime?
In a rare move for a tentpole blockbuster still months away from its premiere, the current runtime for Avengers: Doomsday has already been revealed.
According to The Hollywood Reporter, the film clocks in at 165 minutes (2 hours and 45 minutes). While the outlet notes this could change, it can only be altered by a few minutes, considering that tickets are already available in advance.
At 165 minutes, Doomsday would be longer than 2018’s Avengers: Infinity War (149 minutes), but shorter than 2019’s Endgame (181 minutes), which might just be the right amount of time, since Doomsday is set to be on an ambitious par with Endgame, story-wise and cast-wise.
For now, fans can wait until Avengers: Doomsday premieres on the big screens on December 18, 2026, with Secret Wars positioned to release on December 17, 2027. Stay tuned!
