<P> The fight scene during the romantic dinner that Gosling's character Sebastian prepared for Mia (Emma Stone) was one of the scenes that was re-written more than any other . Gosling and Stone also helped create the dialogue of the scene to get it to be one of the more realistic scenes in a film filled with fantasy and fantastical elements . </P> <P> Chazelle spent nearly a year editing the film with editor Tom Cross, as the two were primarily concerned with getting the tone just right . </P> <P> The songs and score for La La Land were composed and orchestrated by Justin Hurwitz, Chazelle's Harvard University classmate, who also worked on his two prior films . The lyrics were written by Pasek and Paul, except for "Start a Fire", which was written by John Legend, Hurwitz, Marius De Vries and Angelique Cinelu . </P> <P> A soundtrack album was released on December 9, 2016, by Interscope Records, featuring selections from Hurwitz's score and songs performed by the cast . </P>
