Marvel's Avengers: Endgame.
Hawkeye has had a rough few years in the MCU. After attempting to retire at the end of Black Widow sacrificed her life to get the Soul Stone on Vormir.
Clint Barton has been ready to hang up his bow for a while, but in Hawkeye he'll it on to someone else instead. The role of Kate Bishop has yet to be cast, since Hawkeye likely won't go into production for another year, but Renner himself appeared onstage during the official announcement and offered a few details about what to expect from the show.
"What I get to do in the show ultimately is shepherd an amazing character, ultimately a better version of me and the sentiment of that is the fiber of what Hawkeye is, at least what I think Hawkeye is — a superhero without superpowers and I get to teach someone else to be a superhero without super powers.”
Kate Bishop was first introduced in Young Avengers #1 in 2005, when her sister's wedding was ambushed by a group of bad guys. The Young Avengers showed up and quickly botched the rescue attempt, but Kate managed to save the day. Afterwards, Kate ed Cassie Lang in applying to the Young Avengers and, using the always-useful superpower of having a lot of money, bankrolled the team's costumes and secret lair. She ended up using Hawkeye's bow and arrows (Hawkeye was dead at the time) and after Hawkeye was resurrected he eventually officially ed his superhero name on to her.
No Avengers movies have yet been announced for the MCU Phase Four, so it's very possible that Hawkeye will be Renner's only appearance in the MCU during Phase Four. The Marvel Disney+ TV shows are expected to tie into the movies a lot more than previous Marvel TV projects like the Inhumans did, so it will be interesting to see how Hawkeye fits into the bigger picture.
