ok, some 'take with a grain of salt' DC universe Superman/Batman movie rumors [View all]
.. in case you didn't already read it over at AICN:
Apparently the recent decision to push the Man of Steel sequel back 10 months caused some layoffs and reassignments of the production crew. One of them is supposedly pissed off enough to spill the beans on what could be major plot points (or made up fan-boy stuff or whatever)
-The villians are Lex Luthor and Metallo
-Batman forms a UN type deal to stop Superman from destroying another city
-Aquaman is in it, but not called Aquaman. Hes there because the world engine in the ocean did something to the fish
-Wonderwoman poses as a Wayne Enterprises investor to retrieve an item that belongs to her people.
-Lex Luthor is in the shadows a lot, a manipulator. Not much face time with Superman.
-Robin betrayed Batman at some point, leading to a falling out between them
-The Batcave was super cool looking, and the mobile looked similar to Burtons
-Lois is investigating Lex.
-Metallo kills Clark
-The Daily Planet is bought by Lex Luthor for PR purposes
-At the end Superman is living in exile, and the Justice League is an government approved superhero team.
