We've known this for some time now but Anthony Mackie is Captain America! If you've seen "The Falcon and Winter Solider" then you know that Anthony Mackie pretty much becomes Captain America but now we'll be able to see Anthony Mackie as "Captain America" in a new upcoming movie "Captain America 4."
At this moment we don't know if Sebastian Stan will be part of the movie but I hope so.
While we're waiting for more info, enjoy the new trailer for the next Marvel Movie "The Eternals"
