The Marvel Comics character Hawkeye first appeared in Tales of Suspense #57.
Hawkeye was originally a villain, a variation of this concept was in play during the Avengers movie, where Hawkeye was turned villainous under Loki’s mind control.
Actor Jeremy Renner has portrayed Hawkeye in Thor, Avengers, Avengers: Age of Ultron and Captain America: Civil War.
In the Comics, Clint Barton grew up in the Circus, but in the Marvel Cinematic Universe not much is known about his past.
In another interesting variation from source material, in Age Of Ultron Hawkeye pushes for Wanda Maximoff to become an Avenger, leaving behind villainy. In the Comics, Jarvis invites Hawkeye to the Avengers Mansion to become an Avenger after Hawkeye saved his life.
Hawkeye first appeared in the Marvel Cinematic Universe in Thor as a S.H.I.E.L.D agent. He is called upon to take down Thor (who is de-powered and looking to retrieve Mjolnir) and seen going for a rifle, then passing it up for the Bow. He jumps into a high reach bucket suspended from a crane (with no fall protection!) and gets swung around to a vantage point. After getting impatient awaiting orders he exclaims: “You better call it Coulson, cause I’m starting to root for this guy.”
In the Comics, Hawkeye was married to Mockingbird, who was featured in live action during a run on Agents of S.H.I.E.L.D. In the series, Mockingbird’s character was formerly married to Hunter, whereas in Avengers: Age of Ultron it is revealed that Clint Barton had a family all along.
I really enjoy Jeremy Renner’s depiction of Hawkeye, but I do feel the character is slightly underused in the Marvel Cinematic Universe. At least it seems, each appearance has improved on the character. I particularly appreciate the chemistry he has with Black Widow (as a brother) and with Scarlett Witch (as a father figure).
One of the things I love about Marvel Comics and also their Cinematic Universe is the supporting characters, I always feel like they are waiting for their moment to take the spotlight, or like Hawkeye, take that shot!
But hey, maybe we’ll eventually get that Black Widow/Hawkeye movie we’ve all been dreaming of!
