I am not a screenwriter in any shape or form, but thoroughly enjoyed this episode of Script Notes, where John August interviews writer and director Christopher Nolan - The Dark Knight Trilogy, Dunkirk, Oppenheimer - on his screen writing process.
I was impressed by the amount of research that he does for his films. In the podcast he spends some time talking about Oppenheimer. While on reflection it might appear obvious to have to do the amount of work that he does do in order to create and accurate and compelling movie, I had simply not considered that before.
One of my personal take aways from the podcast was that Nolan tries to keep to a strict working day in his writing process. Though if inspiration hits him, he looks to get the ideas out of his head there and then, and not leave them until he next sits down to try and capture them, as they’ll be long gone by then.
