1. Green Arrow
I mentioned how Black Canary's presence could open the door to Green Arrow appearing, but why not have the emerald archer become a fully fledged member of the Justice League? The fact that The Flash has his own TV show certainly isn't stopping another version of the Scarlet Speedster appearing here, and Oliver Queen brings the same human element Steve Trevor would...with the addition of awesome trick arrows. A TV budget and grounded tone has stopped Arrow from really embracing some of the more outlandish side of Green Arrow's weapons, but that's something Zack Snyder could have fun exploring here (the character's role in The Dark Knight Returns has to mean the filmmaker has given the hero at least some thought). Plus, if this opens the door to that long in development Green Arrow: Escape from Super Max movie, even better. Who would you like to see replacing Green Lantern in the Justice League movie?
