I love the idea of thinking of cinema as not that far from music. A lot of my favourite movie makers, the way they move their cameras or the way they cut just feel very musical - even if the movies have no music in them at all.

I love the idea of using film language similarly to how musicians use music - combining images and sounds in a way that they create an emotional effect.

'La La Land' is about the city I live in. It's about the music that I grew up playing; it's about movies that I grew up watching. Even the big spectacle of the movie feels private to me in that way.

I love movies where you can sense that the director risked biting off more than they can chew.

I love being in the editing room and playing with tempo and with the rhythm of shots.

I hadn't seen that many movies that really go deep enough into the fears of playing music or the language that musicians can use to treat each other or, like, the way that you can see it dehumanize and the way that it can feel like boot camp.
