Marvel has unveiled a new Avengers: Doomsday trailer starring Doctor Doom
It was shown exclusively to Cinema Con 2026 attendees
Unhappy MCU fans want it to be released to combat AI fakes
Marvel has revealed a fresh trailer for Avengers: Doomsday — and fans are incredibly unhappy that it hasn't been released publicly.
Unveiled yesterday (April 16) during Disney's Cinema Con 2026 presentation, the new teaser includes the first footage of Robert Downey's Jr's Doctor Victor von Doom, aka the highly-anticipated movie's primary antagonist.
According to those present in the room, other highlights from the trailer include a soul-swelling reunion between Thor and Steve Rogers, Shang-Chi fighting Gambit, and Yelena Belova battling Mystique with the latter disguised as the former. Oh, and Thor attempting to strike Doom with Stormbreaker; an attack that the incredibly powerful Latverian sorcerer easily stops with one hand.

Spider-Man 4's first clip sparks new theory over possible connection to Avengers: Doomsday
The latest look at the hugely exciting Marvel movie comes four months after the comic book giant released four bite-sized teasers for its next Avengers project. That quartet focused on Chris Evans' return as Captain America in Doomsday, Thor asking his father Odin to help him win one final battle, some menacing mutant mayhem involving the Fox-Verse's X-Men, and a team-up between the Fantastic Four and the Wakandans.
Unfortunately, the film's fifth teaser hasn't been released publicly — and Marvel has moved quickly to issue DMCA takedowns of footage from Disney's presentation that's leaked online. So, what gives?
Why can't I watch the new trailer for Avengers: Doomsday?

Unlike the aforementioned teasers, Avengers 5's latest round of footage won't be made available. That's because trailers debuted at Cinema Con are only shown exclusively to those who are lucky enough to be in attendance.
Predictably, Marvel Cinematic Universe (MCU) fans have been left incredibly frustrated. Indeed, threads on Reddit and the Reset Era forums, plus social media platforms like X/Twitter, are full of comments from disgruntled individuals.
The common consensus among many aggrieved fans is that, in light of multiple news outlets publishing descriptions of said teaser, Marvel should just make it available for everyone to enjoy. Furthermore, MCU diehards believe releasing it would also put an end to the numerous fake AI trailers that have already appeared online in the hours since Disney's presentation ended.
"Marvel is blue-balling us right now," Reddit user Miserable-Ebb 8803 lamented. "Oh my lawd [sic], please release the trailer," nyr 00nyg pleaded after reading a description of the teaser, before goofygoober 2213 wrote: "I usually don't like leaks, but I need someone to leak it already bro."
Meanwhile, You Ok 5376 opined: "Why gate-keep the trailer from the general audience?", while The Very Rare Guy said: "Bro, I don’t wanna read about it. Where’s the goddamn trailer?"

"I never understood for years why these trailers were shown exclusively to attendees (as if attendees already didn't get plenty of benefits for going)," Necessary Trouble 2041 added. "They'd really rather get people to read a description of it ahead of the release, which would lower the impact the trailer would have had had it been seen for the first time."
"I've never understood this strategy of waiting days or weeks to release trailers after these private viewing events," xsupajesusx agreed. "Either you get to see some s****y boot leg leaked cell phone video, or you read/get spoiled by the description from people that saw and get a lackluster first viewing once they finally release it for the general public."
When will Marvel release the new trailer for Avengers: Doomsday?

There's no guarantee that they will. Trailers shown at events like Cinema Con are usually reserved for those lucky enough to go to them, so we might never actually see this specific teaser.
Okay, it's likely that some footage from the Marvel Phase 6 film's newest teaser will be used whenever an official trailer debuts online. I'll be very surprised, though, if this exact video is ever released to the public.
All of that said, Marvel Studios will eventually give us an official trailer to pore over — so, when will that be?
On Reddit, user mdhughes 23 theorized that it drop at some point during the NBA Playoffs, which will be broadcast live on ESPN, aka the sports channel owned by Disney. These begin on April 18 and could potentially run until June 19, which means a teaser could arrive anytime within a two-month window.
Meanwhile, fellow Redditor Go Green Sox stated their belief that it could run ahead of The Mandalorian and Grogu (TM&G).
The first Star Wars movie in seven years will make its theatrical debut on May 22. Considering the iconic sci-fi franchise is also owned by Disney, it's not outlandish to suggest that a Doomsday trailer could be shown ahead of TM&G. After all, Disney released each of the MCU film's first four teasers during Avatar: Fire and Ash's (another film property own by Disney, FYI) first four weeks in theaters last December, so there's a precedent for the House of Mouse doing something like this.
Interesting as those hypotheses are, though, I can't see Marvel releasing an official trailer for Avengers: Doomsday publicly until late July, which is when San Diego Comic-Con (SDCC) 2026 will take place.
Apart from the odd absence, the comic titan always holds a panel at SDCC, with past presentations have included major announcements and trailer reveals. In my mind, then, SDCC 2026 — and, therefore, late July — is the earliest I expect to see a proper teaser for one of this year's most exciting new movies.
