Batman’s worst nightmare comes true when his identity is revealed – by his latest foe, Superman.

The Caped Crusader, played by Ben Affleck, has his mask lifted by his fellow superhero as he is held captive in a new teaser for Batman v Superman: Dawn Of Justice.

In Zack Snyder’s sequel to Man Of Steel, Gotham City’s vigilante goes head to head with Metropolis’s saviour (with Henry Cavill reprising his role), as the world wrestles with what sort of hero it needs.

But with the two superheroes at war with one another, a new threat arises, which puts mankind in greater danger than ever.

The new full-length trailer will be unveiled worldwide on December 3.

Batman v Superman: Dawn Of Justice, also starring Gal Gadot, Amy Adams, Laurence Fishburne, Jesse Eisenberg and Jeremy Irons, will open in UK cinemas in March 2016.
