Fan Casting James Gunn's DCU underrated castings

My goal is for the fans of DC comics and movies to have a place to cast their votes on who they believe should be next up to portray our favorite heroes on the big screen. With the castings of Superman Legacy thus far, it seems we may be getting somewhat lesser known actors and actresses. That is why I will be posting some of the less obvious casting choices to be voted on. As we look forward to James Gunn's take on the DC universe, I hope everyone finds this story an enjoyable environment where creativity and imagination can flourish.
