Six key facts at a glance:

Who’s going to be in Avengers: Doomsday?

Confirmed main cast from Marvel’s announcement

Marvel Studios officially revealed the cast in March 2025. The lineup includes:

• Robert Downey Jr. as Victor von Doom / Doctor Doom (Marvel official film page)
• Pedro Pascal as Reed Richards (People)
• Vanessa Kirby as Sue Storm (Yahoo Entertainment)
• Ebon Moss-Bachrach as The Thing (Yahoo Entertainment)
• Kelsey Grammer as Beast (Yahoo Entertainment)
• Tenoch Huerta as Namor (Yahoo Entertainment)

Returning actors from previous Avengers films

Several familiar faces are back:

• Chris Hemsworth as Thor (Yahoo Entertainment)
• Anthony Mackie as Sam Wilson / Captain America
• Paul Rudd as Scott Lang / Ant-Man
• Sebastian Stan as Bucky Barnes / Winter Soldier
• Letitia Wright as Shuri
• Florence Pugh as Yelena Belova
• Wyatt Russell as U.S. Agent

All these returning actors were confirmed in the official cast list (Yahoo Entertainment).

New additions to the Marvel Cinematic Universe

Besides the Fantastic Four and Beast, the cast includes Tenoch Huerta’s Namor, who first appeared in Black Panther: Wakanda Forever. The inclusion of Kelsey Grammer as Beast marks a return for the actor who played the character in 20th Century Fox’s X-Men films.

Why this matters: The casting confirms that Marvel is integrating the X-Men and Fantastic Four into the MCU timeline, using Doomsday as a convergence point.

Is Tom Holland in Avengers: Doomsday?

Why Tom Holland is not confirmed for Doomsday

Tom Holland has not been announced as part of the cast by Marvel Studios. Despite fan hopes, his name is absent from the official list (Wikipedia).

What Marvel has said about Spider-Man’s role

No official statement from Marvel or Sony confirms Holland’s involvement. The character’s film rights are owned by Sony Pictures, which complicates MCU appearances.

The state of the Sony-Marvel agreement

The existing co-production agreement between Sony and Marvel Studios allowed Spider-Man to appear in MCU films like Avengers: Infinity War and Endgame. However, no extension for Doomsday has been announced.

The implication: Until a deal is made public, Spider-Man is effectively out of the Avengers lineup for this installment.

Why is Chris Evans not returning as Captain America?

Chris Evans’s stated reason for leaving the role

Chris Evans has not been announced in the cast for Avengers: Doomsday. He has publicly stated his departure from the role in interviews after Avengers: Endgame.

His character arc in Avengers: Endgame

Steve Rogers retired at the end of Avengers: Endgame (2019), passing the shield to Sam Wilson. The character’s story concluded with him living a full life in the past.

Possibility of a future cameo

Fan theories about his return remain unconfirmed. No official sources suggest a cameo in Doomsday.

The pattern: Marvel is respecting the character’s ending, focusing on new and returning heroes rather than resurrecting retired ones.

Why is Scarlett Johansson not playing Black Widow in Doomsday?

Character death in Avengers: Endgame

Black Widow (Natasha Romanoff) died in Avengers: Endgame (2019) during the mission to obtain the Soul Stone. Her sacrifice is a key plot point.

No current plans for resurrection

Scarlett Johansson has not been announced for Doomsday. Marvel has not indicated any plans to resurrect the character.

Scarlett Johansson’s involvement in other Marvel projects

She received a solo prequel film, Black Widow (2021), which was set before her death. No further projects have been announced for her character.

What this means: Black Widow’s story is complete in the MCU timeline, and her absence from Doomsday is consistent with the narrative.

Is Hugh Jackman in Avengers: Doomsday?

Hugh Jackman’s confirmed role in Deadpool & Wolverine

Hugh Jackman is confirmed to reprise Wolverine in Deadpool & Wolverine (2024), but that film is separate from Doomsday.

No announcement for Doomsday

Jackman is not listed in the announced cast of Avengers: Doomsday (Wikipedia).

Possible future crossover

No official statement from Marvel links him to Doomsday. While multiverse crossovers are possible, nothing has been confirmed.

The catch: Wolverine’s MCU debut is happening through the Deadpool franchise, not the Avengers team-up film.

Does Tony Stark become Dr. Doom?

Robert Downey Jr. plays both characters

Robert Downey Jr. is cast as Victor von Doom in Avengers: Doomsday (Marvel). He previously played Tony Stark / Iron Man for 11 years (Entertainment Weekly).

Comic book origins of Doctor Doom

In Marvel Comics, Doctor Doom is a Latverian monarch and sorcerer, unrelated to Tony Stark. The MCU has not yet explained a connection between the two characters.

MCU reboot or variant theory

Fan theories propose a variant or alternate universe Doom, given the multiverse theme. However, this is unconfirmed speculation.

Why this matters: The casting of Downey as Doom is a creative choice that could retcon or reinvent the character, but no official explanation has been given.

When is the release date for Avengers: Doomsday?

Officially announced release window

Avengers: Doomsday is scheduled for release in 2026 (Marvel). IMDb lists the U.S. release date as December 18, 2026 (IMDb).

Current production status

Filming has reportedly not started as of mid-2025. The cast announcement in March 2025 was the first major update.

Anticipated trailer timeline

A trailer has already been released, offering a first look at Robert Downey Jr. as Doctor Doom (UPI).

The trade-off: With a 2026 release and no filming started, the production timeline is tight, but Marvel has a track record of delivering on schedule.

Timeline of key events

• July 2024: Marvel Studios announces Avengers: Doomsday at San Diego Comic-Con (People).
• March 2025: Marvel releases official cast list via Deadline and social media, revealing Robert Downey Jr. as Doctor Doom (Yahoo Entertainment).
