As the wait goes on for Marvel to release the Avengers: Doomsday trailer recently shown behind closed doors at CinemaCon, people are filling the void by making trailers of their own, using online descriptions of the official trailer to generate fake AI approximations of what to expect.
Clips of fake Avengers: Doomsday trailers that show fights between Gambit and Shang-Chi, Thor and Doctor Doom, and Steve Rogers turning up at the end in dramatic fashion have enjoyed millions of views across social media, with some saying they were misled into thinking they were the real deal.
These trailers use generative AI tools to recreate the leaked trailer effect, as if they were filmed underhandedly by someone who was in the room at CinemaCon itself. They are terrible quality and even include fake audience cheers when characters pop up for the first time. Yes, Steve Rogers once again proving himself to be worthy of Mjölnir gets the biggest (fake) cheer.
X / Twitter account @lordsambrah shared a number of clips that enjoyed millions of views. “I enjoy reposting anything related to Avengers: Doomsday,” they said. “Yes, most of it is likely AI-generated from what I’ve seen, but it’s filling the void created by the lack of official content. That said, I’ll be more disciplined about vetting authenticity going forward.” However, more shares followed, despite community notes.

The clips are ripped from trailers made by a YouTube account called Yellow Minutes, which has a number of fake AI videos under its belt. Video titles include “FULL Avengers: Doomsday Trailer LEAKED,” and “FULL Spider-Man Brand New Day clips LEAKED.”
Comments show a number of people were misled, a mix of criticism and praise. “Even though this is AI, this is essentially what the trailer is going to look like. You even nailed Dr. Doom stopping storm breaker with 2 fingers,” said one person in a YouTube comment.
Misleading videos made by generative AI have exploded on the internet in recent years as the technology has become more popular and accessible. Physicist Brian Cox went public with complaints about YouTube accounts that had used AI to create deepfakes of him saying “nonsense” about comet 3I/ATLAS. Similarly, Keanu Reeves hit out at AI deepfakes selling products without his permission, insisting "it's not a lot of fun." In July last year, it was reported that Reeves pays a company a few thousand dollars a month to get the likes of TikTok and Meta to take down imitators.
GTA 6 has suffered from a similar fake AI problem as Avengers: Doomsday, with misleading images and videos ramping up as fans anxiously await Trailer 3.
Can anything meaningful be done? It seems unlikely that the tech companies behind generative AI will slow down any time soon without regulation. And while there is pressure on social media companies and the likes of YouTube owner Google to crack down on misleading AI content, they are, clearly, failing to stem the tide.
YouTube says it has “specific policies that guide how we treat AI content, including disclosure requirements and labelling.” However, there are no such disclosures on the Yellow Minutes channel and its videos.
Meanwhile, Marvel fans are still wondering when the Avengers: Doomsday trailer will be released, now we’re two weeks on from its CinemaCon reveal. For a description of what the trailer includes from someone who was in the room, head here.
