First thought when the mic came into the shot:
Geez guys. Are you letting go of your standards? You never let something like that appear on camera.
And honestly, I believe this scenario. DC did get kinda screwed by the awesome Marvel movies and the Avengers. So, I can see them being desperate for good ideas. Though, I think a Superman movie with Brainiac as the villain would be good. Though, it would be best to not be the next movie.
Also, Dark Sied would be a great villain for a Justice League movie!
If Marvel didn't already tease Thanos for Avengers.
Yep. So... Luther teams up with Brainiac, Sinestro, and Joker for Justice League?
