La La Land undoubtedly owes much to the musicals of old Hollywood, but in this exclusive look at the movie's special features, it turns out our favorite number was actually inspired by Beauty and the Beast. (The animated version, not the Emma Watson one.)
"Damien wanted it like the Beauty and the Beast waltz, where it's kind of, like, bird's eye looking down at the beautiful couple in love, swirling around the space," choreographer Mandy Moore explains of Mia and Sebastian's last dance. "I think the waltz is that last little bit of shining star of the relationship."
The clip -- part of three hours of bonus footage available with La La Land on DigitalHD now and with the Blu-ray and DVD on April 25 -- also includes insight into how composer Justin Hurwitz weaved together the music for the number as well as behind-the-scenes footage of Emma Stone and Ryan Gosling rehearsing the dance.
ET recently sat down with Moore, who is Emmy-nominated for her work on So You Think You Can Dance, and she revealed that she had six weeks of private training with both Stone and Gosling and explained why the first few joint sessions were filled with "a lot of giggles."
"I would work with Emma in the morning because she is a morning person," she recalled. "She loves to work in the morning and be in early, at 8 o'clock, and Ryan loves to have his day and come later. I would meet with him at 8 o'clock at night and [we'd] work for about two hours."
"He's very hard on himself," Moore said of Gosling. "That happens to me a lot as a choreographer. It's if you don't learn something immediately, the person is like, 'I'm terrible,' and then, 'What am I gonna do?'"
