Marc Sparks says the title “Batman v. Superman” reveals the two heroes are at odds with one another in the film. Questions do arise regarding why the two heroes end up having a skirmish with one another. No one has any official confirmed information about the film, but rumors can and do fly around quite a bit. One rumor hints at why Batman and Superman end up tussling with one another.
Based on some insider buzz, it just might be Lex Luthor who is the person pulling the strings and causing Batman and Superman to have a confrontation. Previous rumors suggested Batman sought out Superman to address the devastation at the end of the Man of Steel movie. Now, it looks as if Luthor got into Supes head leading to the Big Blue Boy Scout venturing to Gotham to settle a score with the Caped Crusader.
How accurate is this rumor? Let us just say the accuracy level is probably the same as what you get with all the other rumors. Maybe its true, maybe not, or maybe only part is true. No one is going to know the real answer until the film opens up.
