In the lead up to Avengers: Endgame, Renner appears quite focused on his original co-stars, as he has continued to share pictures to Instagram focusing on these six heroes.
All five of the characters who made up the original Avengers survived.
While there were many surprising decisions at the end of Avengers: Infinity War as far as which heroes we lost and which ones survived, there was one very clear pattern that emerged.
While the exact fate of Jeremy Renner’s Hawkeye was unknown at the time, this pattern (and the fact we knew Renner had filmed scenes for something for the two Avengers movies) led many to believe Hawkeye had lived, something which has since been confirmed.
