A new plot element has been revealed for Batman vs Superman and it can be seen on screencrush.com. I am just copy - pasting it below.
“At long last, see Batman and Superman square off against each other in ‘Batman V Superman: Dawn Of Justice’, an epic superhero showdown which will change both their lives forever.
Clark Kent doesn’t trust Gotham’s mysterious masked vigilante. Bruce Wayne doesn’t trust the alien who nearly destroyed Metropolis. And Lex Luthor, who hates Superman more than anyone, is manipulating both of them for his own twisted ends.
Choose your side: the Man of Steel or the Dark Knight? Learn the answer to the age-old question – who would win? – in ‘Batman V Superman: Dawn Of Justice’.”.
But, on the overall scenario, does it really reveal anything. I don't think it does. For all the folks who are following the movie , this can be easily deduced from the trailer. Lex Luthor can be seen talking to the senator saying - "devils don't come from hell beneath us - they come from the sky.". Also, from the comic books, we know that Batman has been a thorn on his side since a long time. So, it makes sense that he would manipulate superman using the senator to take care of Batman once and for all and to dispose off Superman using kryptonite later so that his goals of world dominance has no blockage.
However, Lex's plans are thwarted when Batman defeats Superman and later brings him on to his side to fight the - threat - which I am starting to believe that it's the OMACs.
That's all for this post. Please feel free to give any feedback.
