I don't think of 'Macbeth' as the villain. I don't think of 'King Lear' as the villain. I don't think of 'Hamlet' as the villain. I don't think of 'Travis Bickle' as the villain.
— Damien Chazelle

It's easy to show terrible people's behavior on screen, and we all just kind of nod and go, 'Isn't that terrible.' It's more interesting when you can show terrible behavior in the interest of something good.
