I think the other thing that needs to be said, particularly about cast size, is that writing for a smaller cast is easier than writing for a larger one. I watched a Christopher Nolan interview a few years ago (I think just after he had made Interstellar). He talked about how he found keeping casts smaller in his earlier films (such as Memento) allowed him to focus more on storytelling without ostracizing the characters--that he didn't have the experience at that point in his career to grapple with a larger array of characters.

He went on to talk about how Interstellar was more of a return to form in that regard, and how he enjoyed writing it more because it was less stressful.
