Superman is coming back, and he'll have a caped co-star. Man of Steel director Zack Snyder announced today at San Diego's Comic-Con that he was making another Superman film and that it will include Batman—the first time the two superheroes will be united on the big screen. He declined to reveal many details, saying the script is just being written. Warner Bros. then confirmed the first-ever pairing in a statement. Snyder reimagined Superman in his June blockbuster Man of Steel, starring Henry Cavill and Amy Adams, which has grossed more than $630 million worldwide. (More Superman stories.)
