With Avengers: Doomsday now heading into production, new details have been revealed from the star-studded event film. Anthony Mackie, who took on the Captain America mantle in Brave New World earlier this year, is returning to the MCU for a leading role in Doomsday. He’ll appear opposite Robert Downey Jr. as Doctor Doom, alongside a host of other Avengers, in an experience that he promises will give fans the “old Marvel feeling” they have been yearning for.
