Avengers: Doomsday Cast Confirmed: Vanessa Kirby and More Join RDJ

Doomsday is coming — luckily, Marvel has assembled a star-studded lineup for Avengers 5, which is now in production.

Robert Downey Jr.‘s return was announced last year, but instead of playing Iron Man/Tony Stark, he’ll play the evil Doctor Doom. Avengers: Doomsday will reunite the actor with some familiar faces as well as some newbies, including several stars from the upcoming Fantastic 4 movie (set to hit theaters in July).

Marvel revealed several major Doomsday stars on Wednesday, March 26, during a lengthy live stream (over four hours) that showed the actors’ names on the back of director’s chairs.

See the full list of confirmed Avengers: Doomsday cast members below:

• Chris Hemsworth as Thor
• Sebastian Stan as Winter Soldier/Bucky Barnes
• Anthony Mackie as Captain America/Sam Wilson
• Vanessa Kirby as Invisible Woman/Sue Storm
• Paul Rudd as Ant-Man/Scott Lang
• Letitia Wright as Black Panther/Shuri
• Robert Downey Jr. as Doctor Doom/ Victor von Doom
• Wyatt Russell as John Walker/U.S. Agent
• Tenoch Huerta Mejía as Namor/The Submariner
• Ebon Moss-Bachrach as The Thing/Ben Grimm
• Florence Pugh as Yelena Belova/Black Widow
• Kelsey Grammer as Beast/Dr. Hank McCoy
• Lewis Pullman as Bob
• Danny Ramirez as Falcon/Joaquin Torres
• Joseph Quinn as Human Torch/Johnny Storm
• David Harbour as Red Guardian/Alexei Shostakov
• Winston Duke as M’Baku
• Hannah John-Kamen as Ghost/Ava Starr
• Tom Hiddleston as Loki
• Patrick Stewart as Professor X/Charles Xavier
• Ian McKellen as Magneto/Erik Lehnsherr
• Alan Cumming as Nightcrawler/Kurt Wagner
• Rebecca Romijn as Mystique
• James Marsden as Cyclops
• Channing Tatum as Gambit/Remy LeBeau
• Pedro Pascal as Mr. Fantastic/Reed Richards

The biggest surprises among the Avengers 5 cast seems to be Huerta Mejía’s Namor, who was introduced as an antagonist in Black Panther 2, as well as original X-Men movie stars who haven’t been seen in decades. While McKellen and Stewart have made appearances across many films as Magneto and Professor X, respectively, Cumming’s Nightcrawler hasn’t been seen since 2003’s X2.

Avengers: Doomsday is expected to deal with characters across parallel universes, meaning actors can play various roles. Though Chris Evans exited the franchise as Steve Rogers, the original Captain America, in Avengers: Endgame, there have been reports he’ll return as another character in the 2026 movie.

“That’s not true, though,” Evans, 43, told Esquire of the rumors in a January interview. “This always happens. I mean, it happens every couple years – ever since Endgame. I’ve just stopped responding to it.”

Meanwhile, there are more familiar faces working behind the camera. Joe Russo and Anthony Russo will return to direct both Avengers: Doomsday and Avengers: Secret Wars. The brothers previously helmed Captain America: The Winter Soldier (2012), Captain America: Civil War (2016), Avengers: Infinity War (2018) and Avengers: Endgame (2019).

The massive Endgame, which earned over $3 billion, clocked in at a whopping 3 hours — and the Russos expect at least one of their upcoming flicks to match that run time.

“If I were a betting man, I would say the first one is two and a half, and the second one’s three hours,” Joe told Collider in an interview earlier this month.

Avengers: Doomsday will hit theaters on May 1, 2026, while Avengers: Secret Wars is set for May 7, 2027.
