Exclusive: Watch Anne Hathaway & Johnny Flynn in 'Song One' Clip
The film features original compositions by Jenny Lewis and Johnathan Rice who were given the task of creating an album that was a cult classic. Johnny Flynn portrays the singer-songwriter who recorded the album then had a lengthy bout with writer's block.
Rice and Lewis wrote 11 songs for Song One, seven of which are in the film. Once the demos were handed over to Flynn, he would create his own arrangement.
"Little Yellow Dress," which receives its exclusive premiere on Billboard, was one Flynn changed. "When Jenny and I did it, it was much more upbeat," Rice said at the 2014 Sundance Film festival. "I like where he took the song."
