Could it be done? Yes. Would people want to see a Robin Hood like hero jumping off rooftops or slinging various type of trick arrows? That's for them to decide. I was watching a fan film which involved the character, it was pretty decent except for a few things that were a bit misleading. With the write director and writer who both understand what he's about, along with why he decided to protect people with a just a bow at hand, I'm positive it can be done right. With The Flash, possibly Green Lantern, and even Wonder Woman getting their own franchise films, Green Arrow could very well be added onto the slate. Unfortunately enough, the idea of a film has never been proposed and probably won't within the next few years or so. My question is, would you all like to see an adaption take place from the comics?
