‘Avengers: Doomsday’ & ‘Secret Wars’ – Russo Brothers Tease Epic Cast & Back-to-Back Filming: “Anybody in the Marvel bag could show up”

Avengers: Doomsday and Secret Wars are currently the most highly anticipated films in the MCU. While the plot remains tightly under wraps, one thing is certain—Robert Downey Jr. is making his return to the franchise as Doctor Doom, who is expected to be the main villain of both movies.

Since the announcement of Doomsday and Secret Wars, countless rumors have surfaced online, hinting at over 50 characters set to appear. Some are already established in the MCU, others are alternate variants, and some have yet to make their debut.

As for Avengers: Doomsday, only a handful of characters have been confirmed so far, including the Fantastic Four, Sam Wilson, Peggy Carter, Wyatt Russell, and, of course, Doctor Doom himself.

Meanwhile, Secret Wars is also set to feature the Fantastic Four, but the rest of the rumored lineup—including Ms. Marvel, Ironheart, and Wong—has yet to be officially confirmed.

Now Russo brothers recently commented on the characters that might appear and well, their statement makes things only more complicated.

Joe Russo remained vague about the cast, acknowledging that characters like Thor, Hulk, Nebula, Shang-Chi, and Loki were previously reported but could have changed after Marvel’s shift away from Kang. When asked about potential X-Men and Deadpool crossovers, he gave no definitive answer, simply stating that “anybody in the Marvel bag could show up.”

Who knows? I don’t know. I don’t know who we’re gonna see. I still don’t know.

Joe Russo also said the movies will be filmed mostly in London and shot back-to-back, making it an intense and demanding process. He joked about the workload, saying they “may or may not survive” the challenge.

Despite the difficulty, he expressed excitement about the story, describing it as something both audiences and filmmakers will find challenging but rewarding. He emphasized that the project is so engaging that it motivates them to take it on, even with its complexity.
