Fans recently found a connection between the logo for Avengers: Doomsday and the Infinity Stones and believe that this could point to a key plot detail. The logo for Avengers: Doomsday was unveiled recently in a live stream by Marvel.

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.

With the promise of an all-star cast led by Robert Downey Jr. as Doctor Doom and Infinity War and Endgame’s creative team back in action, the fifth Avengers movie could bring back much of the franchise’s lost spark.
