Re: MAN OF STEEL 2: Superman/Batman (2015)
Oh come on it won't be a cameo I still call it an introduction though Bats will probably already be established. I'm really seeing something ala Scarlett in IM2. Christian can definitely not appear as Batman or TDKR will have been erased. But if its a choice between Christian and that no talent Joe from True Blood then bring Christian's Batman back from the dead.
Henry Cavill is Superman/Clark Kent
Stana Katic, Natalie Dormer, Scarlet Johansson or Rachel McAdams, Gal Gadot for Lois Lane
Ben Affleck is Batman/Bruce Wayne
