Emotional and thematic connections, not just settings, inspired Watts' choices. "I thought I'd use the Irish band the Pogues for a modern street riot, but I ended up putting them into the Babylonian sequence. I use Rodgers and Hammerstein for the Huguenots — 'Hello, Young Lovers' — and, oh my God, it's heartbreaking. When you hear, in the voice of a really young girl — my little daughter — 'I had a love of my own, like yours,' it's like it's from a spirit from another world. The music for this movie needs to speak to the human frailty and dignity of the oppressed. Of course, I had to use some Bach."
