“Little Women” director Greta Gerwig had a very specific sound in mind when adapting Louisa May Alcott’s acclaimed novel for the big screen.

“Our first conversation, she said to me, ‘I want the score to be like Mozart,'” composer Alexandre Desplat said during the Variety Screening Series presented by Vudu. “‘But Mozart meets David Bowie.'”

One song stuck out to Gerwig and star Saoirse Ronan when they were shooting the movie.

“I played a David Bowie song for Saoirse while she was watching the book being printed. ‘Moonage Daydream’ was the one we played over and over,” Gerwig said.

Ronan compared her main character, Jo March, to Bowie and said that she always thinks about “Moonage Daydream” when watching the film.

“The movie is totally rock and roll. What Louisa did was revolutionary, and it was a very rock and roll move for a girl to write this book about her sisters and get it sold and keep the copyright and have it be one of the most successful books of all time,” Ronan said. “We both love Bowie — somebody who was so androgynous and fluid and was a real game changer. His music was from another stratosphere. I can see it when I watch the film now. I can see myself listening to ‘Moonage Daydream.’ And I’m like, ‘F— yeah!’ That’s what she’s feeling in that moment. That’s all I think about whenever I watch it.”
