Overview
- Marvel published the first full trailer on Monday, giving the public the same preview shown at CinemaCon and coinciding with early ticket sales for a new Infinity Vision premium format.
- The trailer offers the clearest look yet at Robert Downey Jr. in armored, masked Doctor Doom and depicts him as a uniquely powerful antagonist in the Multiverse Saga.
- Chris Evans appears as Steve Rogers in the trailer and is shown taking up Mjolnir, a brief moment presented by Marvel without revealing plot details.
- The footage explicitly assembles heroes from three cinematic lineages—the MCU Avengers, the new Fantastic Four, and legacy Fox-era X‑Men—while teasing battles and uneasy alliances among them.
- The studio confirmed the film’s December 18, 2026 release and that Doomsday will set up a direct follow-up, Avengers: Secret Wars in 2027, and industry reports of post-production friction remain unconfirmed by Marvel or Disney.
