Hawkeye actually shares a lot of personality quirks with Jeremy Renner now that I think about it…
He’s very energetic. He’s efficient on missions. A bit of a prankster. He’s got a great wisecracking sense of humor that will tend to annoy his teammates from time to time. Can be a bit impulsive and reckless - he’s not one to back down from any challenge. (wandering into potentially spoilery territory now) In Ultimates, he’s a family man. Not sure how the movie’s going to play it though.
