This unleashed a number of delightful tweets, several poking fun at Hawkeye's history of being sidelined. But you know who isn't laughing? Renner's weirdly passionate fan base. (Yes, it exists.)
In addition to expressing their fiery rage on Tumblr, Hawkeye fans created a Change.org petition calling for him to appear in future promotional materials for Infinity War, which comes out April 27.
Though a bit tongue-in-cheek, the petition seems to be an authentic endeavour and not an April Fools' joke.
Below an illustration of Renner emblazoned with the hashtag #JusticeForHawkeye, the petition calls on "Walter Disney" - presumably the company, and not the misnamed deceased mogul - to ensure that the character is featured on "posters and that sweet, sweet merchandise such as popcorn buckets".
"It should be clarified at this point that we are not pursuing an [sic] Renner cut, or Hawkeye edition, but instead a movie trailer where Hawkeye receives a minimum of 2.5 lines," the petition reads.
It later mentions past movies mistreating the character, too: "We believe that in past scenes in previous movies Hawkeye has not been given justice. The inclusion of mind control in such as that in the first Avengers movie was quite frankly offensive."
At press time, 913 Hawkeye stans had signed the petition.
There is no way of knowing whether Renner himself has signed it, but it appears that he does feel a little left out of the promotion. The actor shared a fan-created Entertainment Weekly cover solely featuring Hawkeye on Instagram a few days before Marvel released that final trailer.
On Monday, he shared a photo of himself holding the Infinity Gauntlet at a pop culture convention in New Zealand with seemingly random hashtags such as #warmheart and #hotcoffee.
The photo's caption thanks "all the fans," some of whom probably have the Jeremy Renner app downloaded to their phones. The app was released in March 2017 and apparently lets fans explore "Jeremy Renner's world."
In October, the Ringer described the drama surrounding this app, beautifully referring to his die-hard fans as #RenHive. We hope the app includes updates on his house flipping and projects such as Tag, an upcoming film that follows middle-aged friends who have been playing the same game of tag for 30 years.
See? This guy has so much going on, he doesn't need Disney's marketing department to acknowledge Hawkeye's existence.
For what it is worth, directors Anthony and Joe Russo do appreciate the character. Joe told Screen Rant that Hawkeye would be "on his own journey in this movie," and Anthony added that the character's "unique reaction" to the events that take place in "Captain America: Civil War" put him in "a special spot in this film."
All that is left to do is speculate on what Hawkeye's special path may be. Some believe he was left out of promotional materials because he might surprise viewers by adopting a darker persona he takes on in the comics, called Ronin.
Others joke that he might just be at home with his secret family, which was introduced to viewers in Age of Ultron. Or maybe he left to continue that game of tag?
