Much to the dismay of fans, the archer spent much of 2012's Avengers under Loki's spell. While his ice-blue eyes are gone, Clint Barton (Jeremy Renner) will have a shadow over him for at least part of the Avengers' next outing.

"We got to do some interesting stuff with Hawkeye which is a different kind of dark," writer/director Joss Whedon said, according to Digital Spy (the article has since been removed, quote via MStars). "It's been fun for Jeremy [Renner] because he was possessed for so long last time - it's interesting to not be a zombie!"
