Avengers 4: Every Character Confirmed So Far
20. Captain America
Confirmed By: Chris Evans
Though half of the MCU-loving public probably expected Captain America to be one of the biggest casualties of Infinity War - partly because Chris Evans' contract is up, partly because he died at the end of the Civil War arc in the comics (which is what Infinity War effectively is) - he survived and he's coming back.
Chris Evans confirmed that while Infinity War was officially his last film, he did agree to extend his contract to get Avengers 4 finished, as it simply wasn't possible to fit the story into one film, as he told The Telegraph:
I had six films in my Marvel contract, so I could have said after the third Avengers I was done, but they wanted to make the third and fourth Avengers films as a two-parter. They said they had so many other characters to fit in -- Guardians of the Galaxy, Black Panther, Captain Marvel, Doctor Strange, Ant Man -- and couldn't get them all into one movie. [I agreed] because it made sense. It's going to wrap everything up.
He might still die in this story, so don't get too complacent.
His presence on set was also confirmed by one notorious set visiting Twitter account...
