David Goyer has revealed that Christopher Nolan was unfamiliar with Batman before starting work on the Dark Knight trilogy.
Speaking at a BAFTA and BFI Screenwriters’ Lecture, Goyer said he had to lead the director through the ‘Ten Commandments of Batman’ in the early stages of production on Batman Begins:
“Chris had never read comic books. He didn’t know the world. So he trusted me on that franchise and with Superman to know what was canon – what could be changed and what couldn’t be changed. Early in Batman Begins he said, ‘Does he have to have a utility belt?’, and I said, ‘Yes’. And he said, ‘Why?’ And then he showed me a design and it was all black. And I said, ‘It has to be yellow’, and he said, ‘Oh…’
“I identified the ten things that remained sticky about Batman and Superman. Wrote them up and said to Chris, ‘These are the ten things that should be in the movie. Like the Ten Commandments. As long as we honour that, we’ll be good’.”
Goyer and Nolan also worked on Man of Steel. Both are expected to reunite again for the Man of Steel sequel, despite Nolan’s absence from the official press release for the movie.
