For the unversed, let us share with you that 'Avengers: Doomsday' is the fifth film in the 'Avengers' film series following 'Avengers: Endgame', which was released in 2019. This film is a part of Phase Six of the Marvel Cinematic Universe. Anthony Russo and Joe Russo are directing the film. On the other hand, Michael Waldron and Stephen McFeely are writing the screenplay. Marvel Studios and AGBO are producing the film; meanwhile, Walt Disney Studios Motion Pictures is distributing it.
'Avengers: Doomsday' has a star-studded cast including Chris Hemsworth, Vanessa Kirby, Anthony Mackie, Sebastian Stan, Letitia Wright, Paul Rudd, Wyatt Russell, Tenoch Huerta Mejía, Ebon Moss-Bachrach, Simu Liu, Florence Pugh, Kelsey Grammer, Lewis Pullman, Danny Ramirez, Joseph Quinn, David Harbour, Winston Duke, Hannah John-Kamen, Tom Hiddleston, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, James Marsden, Channing Tatum, Pedro Pascal, and Robert Downey Jr., who will play the role of the new villain, Doctor Doom.
In the film, the fans will see the Avengers teaming up with the Wakandans, the Fantastic Four, the New Avengers, and the X-Men to take on Doom’s multiverse-spanning threat. The film underwent multiple changes before reaching this point. In July 2022, two new Avengers films, 'The Kang Dynasty' and 'Secret Wars,' were announced to conclude Phase Six. However, things took a turn when Jonathan Majors was removed from the project due to legal issues. Shortly afterward, the Russo Brothers added Downey as Doctor Doom, giving the film its new title, 'Doomsday.'
During an April 2025 interview with IGN, Mackie shed light on 'Avengers: Doomsday' and teased that the Russo Brothers’ latest blockbuster will bring back the old Marvel feeling. Then, Mackie said, “We’re supposed to go out this week, and we’ll be out there doing it. Everybody’s excited. I feel with the script and having the Russo brothers back, it’s going to be great. I'm really excited for what this project is going to be. It's going to give the audience that old Marvel feeling that they always had.”
