Early reactions to viewings of Batman v Superman: Dawn of Justice point to a movie that's very dark, with one fan stating that it's even darker than the Christopher Nolan movies in The Dark Knight trilogy.
However, Justice League, the 2017 follow-up to Batman v Superman, won't have as dark a tone.
This is according to Justice League writer Chris Terrio, who also served as co-writer on Batman v Superman. Terrio recently spoke about the difference between the two movies.
"I expect Justice League will be tonally not quite as dark as Batman v Superman," said Terrio to The Wall Street Journal. "From that point of view, I felt compelled to go back and try to lift us and myself into a different tonal place because I think when you write a darker film, sometimes you want to redeem it all a bit."
Terrio also spoke about how he prepared to delve into the world of comic books as co-writer on Batman v Superman. He spent a lot of time looking at DC's books, particularly the works of Frank Miller and Grant Morrison. This gave him ideas for creating the conflict that ultimately pits Batman against Superman in the movie.
Terrio also spoke about how Wonder Woman's first appearance plays into Batman v Superman. He felt that it was important to show her as Diana Prince first and then slowly unveil who she really is later in the movie.
"The fun of it is if you don't immediately reveal her in superhero guise, you get to revel in the moment when she finally does reveal herself," he said. "If you bring in a character in a kinetic way, then you accept the reality more easily."
Terrio admits that working on these two movies has taken its toll and that he doesn't plan on taking on Justice League 2. He called the experience the "most rigorous intellectual exercise I've had in my writing life." But in the end, he admits that he owed putting his all into the work to give comic book fans what they deserve.
Batman v Superman: Dawn of Justice releases on March 25.
