It is too hard to do. To many charactors fill the same rolls.
is practically a god, only krytonite,magic andhumanity can defeat him. He would equate to thor + ironman + hulk. That is a villian not a main good guy character.
Batman = ironman
Flash = tony starks wit, he is fast, but how would that help a lot on the movie and showing the blur?
WW = female thor + black widow? = boring.
Hawkman = thor
Aquaman = hulk + posedian?
MManhunter = also a badass
This movie is just hard to make, they all are too powerful to just throw together. It works in comics and the animated series. But a movie? That shit will make john carter look successful. It would not even make the cost to film back with dvd sales.
There only shot is making supes crazy and everyone else has to stop him, then find out at the end it was luthor and darkseid for a second movie.
But again, to oneshot this withoutbuilding up he other characters will be tough.
