Re: Who should be the villain in the sequel for Man of Steel?
If it's Lex and Metallo, I would love to see Corben's body being taken over for brief moment after they've defeated him.
Perhaps a message is spoken through Corben, for a lead up to Justice League. "I am coming. It will be quick. You will not be prepared. It is inevitable", etc.
The after credits-sequence is one year later with Batman picking up Brainiac's ship on his satetllite's radar. At the Daily Planet, Clark gets to the roof and flies into the sky. Bruce reluctantly pulls up 5 files (5 symbols) on his screen -- Project Justice League. BOOM
