Avengers: Doomsday risks being overstuffed with too many characters from different teams and movies. Marvel should focus on a set Avengers lineup to maintain the importance of the team. Less is more in the Marvel Cinematic Universe - a smaller cast can lead to tighter scripts and stronger character development.

Robert Downey Jr. returns to the MCU with other confirmed actors including stars Chris Hemsworth and Tom Hiddleston, 'X-Men' stars like Patrick Stewart and Ian McKellen, and a good chunk from the studio's 'Thunderbolts.

Avengers: Endgame” shattered box office records six years ago and solidified itself as a cinematic milestone. Now, Earth’s Mightiest Heroes are preparing for their next epic showdown. Marvel Studios has officially announced the cast for Avengers: Doomsday with a live-streamed event on X (formerly Twitter).
