SAN DIEGO - Actor Robert Downey Jr. captivated the audience at San Diego Comic-Con when he dramatically revealed himself as "Doctor Doom" in the upcoming Marvel Studios film "Avengers: Doomsday."

Downey kicked off Marvel's movie successes in "Iron Man" and played the popular character in nine films, but on Saturday appeared wearing Dr. Doom's mask and a green cloak.

"New mask, same task," Downey said to frenzied cheers.

The Russo brothers, who will be directing the movie featuring Downey, said his appearance in the film is "proof of the unimaginable possibilities in the Marvel multi-universe."

The reveal capped a jubilant return by Marvel to Comic-Con's Hall H.

Marvel Studios President Kevin Feige kicked off the panel by saying that due to this weekend's success of "Deadpool & Wolverine," the sprawling Marvel Cinematic Universe had now topped $30 billion in box-office earnings. In a nod to a scene in the movie, a choir sang Madonna's "Like a Prayer" before Feige spoke.

"Deadpool & Wolverine," released Thursday, has already broken one record and could shatter more in its opening weekend. Feige used Saturday's panel to chart the course ahead for the MCU, revealing Ford's character in the next "Captain America" film and revealing "Avengers: Secret Wars and "Avengers: Doomsday" as the titles of the next two films in the epic superhero team-up series. "Doomsday" will hit theaters in 2026.

Feige said all the actors introduced Saturday would appear in the upcoming "Avengers" movies, which will be directed by Joe and Anthony Russo. The brothers guided the "Avengers" franchise through its sprawling storyline capped by "Avengers: Endgame" in 2019 that included the death of Downey's Tony Stark/Iron Man character.

"When we directed "Avengers: Endgame," Joe and I truly believed that it was the end of the road for us in the Marvel Cinematic Universe because we had put all of our passion, our love, our imagination into "The Winter Soldier," into "Civil War," into "Infinity War," climaxing all of it with "Avengers: Endgame," Anthony Russo said. "That four movie run was incredible and it left us creatively spent with all of our emotions on the film. In the time since, through a very special story, Joe and I have come to potentially see a road forward with you."

The mounting enthusiasm for the film at Comic-Con was reflected across the country as the fans rushed to see it in theaters, securing the film as the new record holder for the Thursday preview for an R-rated movie. The comic book film sold an estimated.
