While "Batman v Superman: Dawn of Justice" will go a long way towards establishing the expanded DC Cinematic Universe, it won't set the tone for the rest of the films. According to producer Deborah Snyder, "Justice League" will have a lighter tone than "Batman v Superman," and that has a lot to do with the characters.
"'Justice League' is a little bit lighter, 'cause some of these characters -- you know, Flash tends to be a little bit more comedic, I'd say," she explained.
"One of the things that lightens it is having Flash or having characters that are more optimistic. This movie is particular to characters who are having a crisis of conscience, which sort of draws them together," added director Zack Snyder.
"You didn't have to have seen 'Man of Steel' to enjoy ['Batman v Superman'], 'cause it's a standalone thing. ['Justice League'] will have some references to 'Batman v Superman,' and that story will feel in certain kinds of ways connected to it," producer Charles Roven also shared.
