Saturday's Warner Bros. Pictures panel at Comic-Con International in San Diego concluded in grand fashion, with Man of Steel director Zack Snyder and stars Henry Cavill (Superman) and Harry Lennix (General Swanwick) joining him on stage to announce the team's intention to produce a film featuring both Superman and Batman. No title or other information was revealed besides the fact that it will star Cavill and the displaying of a teaser graphic and Lennix's reading of Frank Miller's immortal words from the famous Superman/Batman fight at the climax of his The Dark Knight Returns:

I want you to remember, Clark…in all the years to come…in your most private moments…I want you to remember…my hand…at your throat…I want…you to remember…the one man who beat you.

Warner Bros. issued a press release shortly after the panel which came with the following facts and remarks about the film, which will unite Bob Kane and Bill Finger's Batman with Jerry Siegel and Joe Shuster's Superman for the very first time on screen.

  • The film's story will be crafted by Snyder and Man of Steel screenwriter David S. Goyer, who will also write the screenplay for the as yet untitled film.
  • Christopher Nolan and Emma Thomas will serve as Executive Producers.
  • DC Entertainment President Diane Nelson: "Superman and Batman together on the big screen is a dream come true for DC fans everywhere. All of us at DC Entertainment could not be more excited for Zack’s continuing vision for the DC Universe.”
  • Man of Steel and Dark Knight trilogy producer Emma Thomas: "Whilst our ‘Dark Knight’ trilogy is complete, we have every confidence that Zack’s fresh interpretation will take the character in a new and exciting direction. His vision for Superman opened the door to a whole new universe and we can’t wait to see what Zack does with these characters.”
