Warner Bros did not treat Batman v Superman: Dawn Of Justice like the big budget studio film that it is, revealed the movie's screenwriter Chris Terrio.

The Oscar winning screenwriter of Argo, who has also penned The Justice League script, spoke to The Wall Street Journal recently about how Warner Bros gave him the freedom to let his voice be heard and develop the film's script and story as per his sensibilities and ideas.

"Given the scale, you would think the whole thing has a corporate stench, but the way we worked there was this quality of, 'I can't believe they're letting us do this.' In superhero stories, Batman is Pluto, god of the underworld, and Superman is Apollo, god of the sky. That began to be really interesting to me — that their conflict is not just due to manipulation, but their very existence."

When asked to share his views on adding Wonder Woman to the mix, Terrio stated: "If you bring in a character in a kinetic way, then you accept the reality more easily."

The writer also shared some rather interesting insights into how he prepared for The Justice League script and bringing all those amazing DC superheroes together on screen for the first time.

Terrio revealed that he studied red and blue shifts in electromagnetic physics to think about the Flash, investigated deep sea biology in the Mariana trench to create the world of Aquaman, and read the Greek historian Diodorus of Sicily's account of the war between Amazon and Atlantis to better understand Wonder Woman.

"If you told me the most rigorous dramaturgical and intellectual product of my life would be superhero movies, I would have said you were crazy," he concluded.
