AVENGERS: DOOMSDAY (2026) — RELEASE DATE, CAST, TRAILER & SOUNDTRACK

The Multiverse Saga is racing toward its endgame, and Avengers: Doomsday is the film built to close it out. The biggest shock of Marvel's next phase is Robert Downey Jr returning to the MCU — not as Iron Man, but as the villain Victor von Doom, aka Doctor Doom. With the Avengers, the X-Men, and the Fantastic Four uniting against him, the official trailer pulled in around 73 million views, and the film lands in theaters worldwide on December 18, 2026.

Soundtrack & Score

The score is officially in the hands of Alan Silvestri, the composer behind the iconic Avengers theme and the music of The Avengers (2012), Avengers: Infinity War, and Avengers: Endgame. According to reports, the teaser material features a piano rendition of his classic Avengers theme — a fitting choice for the finale of the Multiverse Saga.

One thing to be clear about: Marvel has announced no individual songs for the film. The music conversation around Avengers: Doomsday is entirely about the score.

The official trailer, released July 20, 2026 on Marvel Entertainment's verified YouTube channel, runs 2:25 and carries the tagline "Doomsday arrives December 18th." It opens on the X-Mansion, stages a Thor vs. Doom confrontation, marks Chris Evans' return with Mjolnir, and brings the X-Men and Fantastic Four into the crossover alongside Loki's return. Four shorter teasers preceded it, according to reports.

Doomsday shares its December 18 release date with Dune: Part Three, setting up one of the biggest box-office clashes of 2026. The Multiverse Saga is then reported to conclude with Avengers: Secret Wars on December 17, 2027 — a date that remains subject to change.
