Marvel Studios did not plan for this. Avengers Doomsday entered the public eye much earlier than expected. Three teaser trailers leaked online before their official release. These teasers were supposed to be shown only in movie theatres. They were meant to play alongside James Cameron’s Avatar Fire and Ash. Once the clips appeared online, fans quickly started talking about them everywhere.
Reports say Marvel had a careful plan in place. They wanted to release four teasers. One teaser each week starting December 19. None of them were supposed to be online. Only cinema audiences were meant to see them. Despite strong warnings, some viewers recorded the footage inside theatres. The videos were then shared online. Marvel rushed to remove them, but the damage was already done.
The leaked teasers focus heavily on old and loved characters. This is what made fans even more excited. The first teaser has drawn the most attention. It reportedly shows Chris Evans returning as Steve Rogers. The clip hints at Captain America coming back. Marvel has not confirmed this officially. But fans believe the signs are clear.
In the teaser, Steve is seen riding a motorcycle. He arrives at the quiet house last seen at the end of Avengers Endgame. Inside the house, he looks at his Captain America suit. He pauses. Instead of picking it up, he lifts a baby. Fans believe the child is his son, James Rogers. The teaser ends with a message saying Steve Rogers will return in Avengers Doomsday. A release countdown follows.
Earlier this year, Chris Evans denied being part of the film. He said he often talks to Robert Downey Jr. and the Russo Brothers. He also said it feels strange not being back with the team. After the leak, many fans think he said this to protect the surprise.
Industry insider Daniel RPK shared more details. He claimed the first teaser confirms Steve Rogers’ return. He also said Steve will be the emotional center of the movie. According to him, Marvel wants Steve to lead the story in Avengers Doomsday.
The other leaked teasers reportedly show Thor and Doctor Doom. Chris Hemsworth returns as Thor. Robert Downey Jr. appears as Doctor Doom. These clips are said to set up the main conflict of the film. There are also talks that Marvel may undo or reduce parts of the post Endgame timeline. This comes after mixed reactions to newer characters. The studio may be shifting focus back to familiar faces.
The film has a massive cast. It includes Chris Hemsworth, Anthony Mackie, Sebastian Stan, Tom Hiddleston, Paul Rudd, Letitia Wright, Winston Duke, and Robert Downey Jr. Other names include Simu Liu, Florence Pugh, David Harbour, Wyatt Russell, Pedro Pascal, Vanessa Kirby, Patrick Stewart, Ian McKellen, James Marsden, and Channing Tatum.
Avengers Doomsday is directed by the Russo Brothers. The script is written by Stephen McFeely. The film is set to release on December 18, 2026. Avengers Secret Wars will follow on December 17, 2027.
