Avengers: Doomsday's cast has a stacked lineup of 61 MCU actors who could propel its story to new heights, including Anthony Mackie, Robert Downey Jr., and Florence Pugh.
Avengers 5's cast is already making headlines due to the overwhelming number of actors that will be featured in the crossover movie. Interestingly, Avengers: Doomsday has 10 actors over 50 years old, and it will highlight characters from the 616-MCU and the wider Multiverse.
Every Rumored & Confirmed Actor in Avengers: Doomsday Cast
Based on a report from Jeff Sneider on The Hot Mic, the following are the rumored cast members appearing in Avengers: Doomsday:
Mark Ruffalo - Bruce Banner
While he was not part of the official cast announcement of Avengers: Doomsday during the Marvel Studios livestream, Mark Ruffalo is rumored to reprise his role as Bruce Banner in the fifth Avengers movie.
Benedict Wong - Wong
Although it is still rumored, as the MCU's current Sorcerer Supreme, it is a no-brainer that Wong (played by Benedict Wong) would return to help fight the Multiversal threat in Avengers: Doomsday.
Brie Larson - Carol Danvers
Brie Larson's Captain Marvel is another Avenger rumored to return in Avengers: Doomsday. Carol Danvers' looming comeback makes sense since she has unfinished business bringing Monica Rambeau home after being trapped in a different universe.
