If you want to do deep emotional things, you have to deal with major themes. Some traditionals answer that all writing is about Love and Death, which is a title of a Woody Allen movie.
“I think all movies, but maybe my movies more than others, are explorations of perception, explorations of the world, and they don’t have, like, pre-chewed answers, so it’s meant to surprise you; it’s meant to put you off-balance. It’s meant to provoke some kind of thought process where you have a dialogue with what’s going on on the screen.“
Olivier Assayas
