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'.

Incidentally, an earlier spoiler report by Badass Digest stated, "It is Superman who goes to Gotham and starts the confrontation... at the behest of Lex Luthor." So looks like the shrewd and menacing Lex Luthor will get Batman and Superman to lock horns in the film. But what could his own twisted ends be? Could it be part of a larger plot that unfolds in the subsequent Justice League films? Fans may have to wait to find out.

Batman v Superman stars Ben Affleck as Bruce Wayne/Batman, Henry Cavill as Clark Kent/Superman, Gal Gadot as Diana Prince/Wonder Woman, Jesse Eisenberg as Lex Luthor, Jeremy Irons as Alfred with Amy Adams, Laurence Fishburne and Diane Lane returning from Man of Steel. Ray Fisher will appear as Cyborg and Jason Momoa will also be making an appearance as Aquaman. Dawn of Justice is set to open in theaters on 25 March 2016.
