Extrait d'une interview de Chazelle :
I was kind of lucky in the sense that La-La Land worked out that way even without my having planned for it. I had written it before we shot Whiplash, and for awhile, I thought I might even make La-La Land before Whiplash. It’s just a bigger scope project so it was harder to get off the ground without much previous directing experience. So Whiplash went first. But as soon as Whiplash was done shooting, I knew what I wanted my next movie to be. There was never a question. It was just about hitting the ground running right after Sundance and locking up the financing. We’re in sort of pre-prep, and the shoot itself is later in the year—fall. It’s set in contemporary L.A., but it’s very much an homage to that kind of Technicolor, Cinemascope, ’50s musical—A Star is Born, Seven Brides for Seven Brothers, It’s Always Fair Weather. Miles is the lead, and we’re still casting the rest. Nothing else [in the cast] is certain. We’ve been scouting the past few months and choreographing and putting the final touches on the music.
Donc apparemment, l'influence principale n'est pas Demy, mais les comédies musicales des 50's.
Et Emma Watson n'est pas confirmée.
