Robert Downey Jr. Teases Doctor Doom’s Next Move, and ‘Avengers: Doomsday’ Fans Think a Big Reveal Is Imminent
Few casting stories have kept Marvel fans guessing quite like Robert Downey Jr.’s return as Doctor Doom. The actor spent years as Iron Man, so seeing him step into the villain’s armor for ‘Avengers: Doomsday‘ was a shock when the casting of Downey as Doctor Doom, the return of the Russo brothers and the new subtitle were all announced in July 2024. According to Variety, having the Russos direct both films was a top condition for Downey’s return.
The marketing rollout since then has been anything but conventional. Marvel has released just 1 official trailer, back in July, while everything since has arrived as special looks and teasers, including a World Series spot. The studio also ran a Doomsday Clock livestream that revealed the film’s global tour cities, and ‘Avengers: Endgame Encore’ adds 4 minutes to the 2019 cut, including an end tag that Joe Russo describes as a bridge into ‘Doomsday’.
Into that carefully managed hype cycle stepped Downey himself. On Thursday afternoon, he posted a silent video to Instagram, with a caption urging his subjects to be patient, adding that time will tell but Doom won’t. The video also features the same ticking clock sound as the one playing in Marvel’s official Doomsday Clock livestream.
The timing of the post has fans convinced that something big is around the corner. Empire dropped the cover story for its special ‘Doomsday’ issue and teased that something else was arriving at 4 PM the next day, and GamesRadar suspects it may be the final trailer ahead of the film’s release.
Marvel Studios has not confirmed the rumor. Still, the post pulled in more than 680,000 likes in its first 4 hours, which shows how hungry fans are for fresh footage. The first trailer already hit 503 million views for the second biggest launch in history.
Part of the intrigue is how little Marvel has explained about Downey’s version of the character. Kevin Feige used the Empire feature to insist that Downey is playing Victor Von Doom, not a Tony Stark variant, putting a popular fan theory to rest. The mysterious character has been described as a gothic villain, with a backstory paving the way for a much scarier story than fans expect.
The villain has also been busy in the wider MCU. Doom has been visiting and picking up characters like Hulk and Scarlet Witch, and a surprise post-credit scene in the ‘VisionQuest’ finale reveals the scope of his plans for ‘Doomsday’. Fans are now left to read every new tease for clues about what he has in store for the rest of the heroes.
Footage shown in Hall H at Comic-Con made clear that Doom is an old pal of the Fantastic Four, and it showed him repelling Thor with an energy blast.

The film brings the Avengers, Fantastic Four, X-Men and Wakandans together. Chris Evans, Chris Hemsworth, Pedro Pascal and Anthony Mackie are among the big names, alongside returning X-Men actors including Patrick Stewart, Ian McKellen and James Marsden.
The story is built around 3 colliding universes, which could be the MCU timeline, the X-Men timeline and the Fantastic Four timeline. The Russos have described ‘Doomsday’ as the first half of a transition from the Multiverse Saga into the Mutant Saga.
There is also talk of even bigger surprises. The Writers Guild revealed Ryan Reynolds and Hugh Jackman among 10 credited writers on the film, which has fueled belief that Deadpool and Wolverine will appear. Marvel hasn’t officially confirmed that casting.
‘Avengers: Doomsday’ opens exclusively in theaters on Dec. 18, and tickets are already on sale. It will eventually release on Disney+, but that date is not known yet. The sequel, ‘Avengers: Secret Wars’, is set to be released on Dec. 17, 2027.
Filming wrapped after a 2025 shoot at Pinewood Studios in England, with location work in England and Bahrain, and the Russos have confirmed that ‘Secret Wars’ is already in pre-production. With only weeks left before release, every new post from Downey now feels like it could be a countdown.
Do you think Robert Downey Jr.'s cryptic post means a new 'Avengers: Doomsday' trailer is coming soon?
