"Well, I chose that one specifically because we haven't gotten a chance to tell Clint Barton's story. You've seen Thor have several movies. You know his backstory. Cap has several movies, Tony has a few, so they've all had their chance, and Clint Barton hasn't gotten a chance to tell his past."
I am so glad for this. Hawkeye is one of my favourite characters, and I have always been disappointed that he never really got explored like there other original Avengers.
I don't know if they're going to go for the circus origins or change it, but I can't wait to see what they do. Hopefully the include his time with S.H.I.E.L.D. and maybe even meeting Black Widow (if not shown in her movie).
