Superman and Batman will be in the same film together for the first time. Zack Snyder, the director of the latest Superman movie "Man Of Steel" said the movie would be out in the summer of 2015. He said fans of the superheroes would be happy they are going to team up. Henry Cavill, the star of "Man Of Steel," will play Superman in the new film. No one knows which actor will play Batman. Movie fans are hoping for an action-packed adventure like no other superhero film. Mr Snyder didn't 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 successful, like "The Avengers". That movie made $1.5 billion worldwide, uniting the main characters of Marvel Comics. Warner Bros. and DC Comics (the owners of Superman and Batman) spent many years trying to agree to the new film. Snyder said it would be amazing because the two greatest superheroes in the world would work together. He said it was "beyond mythical". However, some fans are worried about the new movie. They think the story needs to be extra-special to be successful.
