La La Land follows two dreamers looking to find fame in Los Angeles, who meet and discover a love connection. There is aspiring actress Mia (Stone) who is lonely and trying to fit in to a confusing new city, and cocky, charismatic jazz pianist Sebastian, who learns that juggling a relationship and art in the unforgiving City of Angels is no easy task.
And when you have to contend with someone called Boss (Simmons), you have even more reason to worry. Although he could be in a more laid back mode for this one.
It's perhaps not surprising to see Simmons reuniting with the man who helped him win an Academy Award® early this year.
The film will also feature Jessica Rothe (Parallels), Sonoya Mizuno (Ex Machina) and Callie Hernandez (Machete Kills) in the ensemble, playing Stone's roommates. Chazelle is looking to shoot this year ready for a 15 July 2016 release.
