The Russo brothers present that Marvel has an ingenious contrivance of working out which actors they’ll utilize for upcoming Avengers motion pictures

Avengers: Doomsday is expected to be the most significant superhero assembly since Avengers: Endgame, so it’s no surprise that the creative team behind the film has devised a method for keeping track of all the characters. Luckily for them, there’s a clever solution in play — a collection of baseball cards.

The Russo brothers, who are helming both Doomsday and the sequel Avengers: Secret Wars, recently discussed this innovative strategy for identifying which actors are available. They previously employed it for their earlier MCU films.

“Yes, we continue to utilize the baseball cards,” confirmed Anthony Russo during a conversation with The Hollywood Reporter.

“Now they come with magnets, so we can place them on a board and view them,” added Joe Russo, noting that “it’s the only way to manage the sheer number of characters we’re collaborating with.”

“And when it comes to determining who appears in the movies, it’s a lengthy creative journey of uncovering the direction we wish to take the narrative. What is the most surprising and thrilling path for us to explore, and which characters aid us in that mission?” Anthony elaborated.

This filmmaking duo is behind the most densely packed superhero films in the Marvel universe, from Captain America: Winter Soldier and Captain America: Civil War to the final two Avengers films. They are set to return to the franchise with the highly awaited Doomsday, which is slated for release next year.

While most information remains tightly sealed, the Russo brothers have provided hints about the forthcoming film. They recently dismissed the leaked Avengers: Doomsday concept art, stating there was “nothing spoilery” in those images, and revealed the comics that inspired them, showcasing titles that may illustrate how Doctor Doom fits into the storyline.

Until we receive more insights, you can check out their recent film, The Electrical State, which just premiered this week on Netflix.

Avengers: Doomsday is scheduled to premiere in theaters on May 1, 2026. For more, take a look at our compilation of all the upcoming Marvel films and series you need to be aware of.
