Re: LA Times is reporting that WB will announce World's Finest movie for 2015 - Part
Batman is paranoid by nature and will be suspicious of Superman at first. He's been preparing for such a confrontation since Zod appeared, so he will have a plan. Batman will be the antagonist at first, then they will team up against a common foe (I'm thinking Lex). WW cameo at the end to set up a Trinity movie.
