A sequel to this year's Superman movie Man Of Steel will feature a face-off with Batman, according to director Zack Snyder.
Snyder revealed the plans whilst speaking to more than 6,000 comic book fans at a convention in San Diego.
Man Of Steel was released in the UK in June and featured British actor Henry Cavill as Superman and his alter ego Clark Kent.
Cavill will reprise his role in the new movie but it is not yet known who will play Batman, given that Christian Bale's involvement in the project is in doubt.
Man Of Steel stars Amy Adams, who plays Lois Lane, and Laurence Fishburne would also return, Warner Brothers said.
The sequel is expected to come out in 2015 and production company Warner Bros has confirmed that it will feature the two superheroes battling each other.
Shortly after the revelation at the event in San Diego, Snyder issued a statement via Warner Bros saying: "Let's face it, it's beyond mythological to have Superman and our new Batman facing off, since they are the greatest superheroes in the world."
Warner Bros also confirmed that Christopher Nolan, director of the latest three Batman movies - Batman Begins (2005), The Dark Knight (2008) and The Dark Knight Rises (2012) - will act as executive producer for the new film.
Comic book superhero movies have proved extremely successful at the box office in recent years. Man Of Steel has already grossed $621 worldwide, while The Dark Knight Rises topped $1 billion.
Greg Silverman, president of creative development at Warner Bros, said Snyder was ideally suited to bringing Superman and Batman together. He said: "Zach Snyder is an incredibly talented filmmaker, but beyond that he's a fan first and he utterly gets this genre."
