“If he would have said no, our roads would have been very different and there certainly wouldn’t have been a La La Land,” the director says. “The smartest decision I ever made was to latch on to him and not let go.”

When Chazelle and Hurwitz finally got the green light to make La La Land, they wrote and composed hand-in-hand. The first task Chazelle put to the composer was to come up with a main theme.

“I spent so much time at the piano working on demo after demo, idea after idea,” Hurwitz says of what became “Mia & Sebastian’s Theme.” “As soon as I came up with that melody, it was like an “A-ha!” moment for me and Damien: ‘OK, wow, that’s the theme of the movie.'”

He and Chazelle also asked their stars, Emma Stone and Ryan Gosling, to help create the sound of the film by singing some of the songs live on camera while Hurwitz played the keyboard backstage.

“We did that because we wanted those really intimate moments to feel live and to have that live vulnerability,” Chazelle says, “and to let Emma and Ryan really act those moments and those songs in a way that probably wouldn’t have happened if they had to pre-record those songs in a studio months earlier.”

That sometimes unorthodox approach that Hurwitz and Chazelle took to collaborating has paid off. But the director says their sentimental musical was never a sure bet.

“The idea of embracing that, not apologizing for it, not trying to coat it in any kind of irony, and also embracing the kind of emotions that can come with that, that I feel like we downplay in movies these days,” Chazelle says. “The sort of full-fledged romanticism that movies of an earlier era were able to embrace without hesitation, and now it feels like we’re a little scared to embrace those sometimes.”

Chazelle has another movie in the pipeline, although it’s not a musical. As soon as it gets a green light, Hurwitz says, he will sit back down at his piano to compose once again.
