Superman and Batman will be in the same film together for the first time ever. The movie will be in cinemas in the summer of 2015. Zack Snyder, the director of the latest Superman movie "Man Of Steel," told reporters the news on Saturday. He said many fans of the two superheroes would be happy that the two characters are going to team up. Henry Cavill, who starred in "Man Of Steel," will play Superman again in the new film. The producers don't yet know which actor will play Batman. Moviegoers are expecting an action-packed adventure that will be like no other superhero film. Mr Snyder said he could not give away any secrets about the story because the script hasn't been written yet.

The movie company Warner Bros. hopes the Superman-Batman duo will be as successful as the 2012 film "The Avengers". That movie made $1.5 billion worldwide and successfully brought together the main characters owned by Marvel Comics. Warner Bros. and DC Comics (the owners of Superman and Batman) have spent many years trying to agree to the new film. Snyder told reporters just how great he thought the new movie would be, 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." However, some fans are worried about the new movie. They think the story needs to be extra-special to be successful.
