A new trailer for next year's Batman v Superman: Dawn of Justice has been unveiled at Comic-Con in San Diego.
The Ben Affleck and Henry Cavill-starring film opens in March 2016.
Studio Warner Bros says: "Fearing the actions of a god-like superhero left unchecked, Gotham City's own formidable, forceful vigilante takes on Metropolis's most revered, modern-day saviour, while the world wrestles with what sort of hero it really needs.
"And with Batman and Superman at war with one another, a new threat quickly arises, putting mankind in greater danger than it's ever known before."
