Rob Keyes at Screen Rant got to visit the set of Avengers: Infinity War last summer, and he asked the question that's on everybody's mind: where is Hawkeye? The Russo brothers, co-directors of the film, were quick to assuage our fears and explain what's happening to everybody's favorite superhero:
Joe Russo: Hawkeye, coming out of Civil War, is in the same position that Cap and Falcon are at the end of that movie. And Ant-Man. And coming into this movie characters who were on Cap’s side coming out of the Civil War. Some made certain decisions and others made other decisions that led to different paths in them dealing with oversight in this movie in a different way. So Hawkeye’s on his own journey in this movie.
Anthony Russo: Yeah. He has a unique reaction to the Civil War situation that puts him in a special spot in this film.
Keyes also mentioned that during the visit, he saw a prop that hints at Hawkeye's special journey (OP note: Hawkeye is totally going to turn Ronin in Infinity War).
