La La Land is a 2016 romantic musical written and directed by Damien Chazelle and starring Ryan Gosling, Emma Stone, John Legend and Rosemarie DeWitt.
The plot follows a musician and aspiring actress who meet and fall in love in Los Angeles.
The film's title is a reference to both a nickname for the city of Los Angeles as well as a euphemism for a state of being out of touch with reality.
It is the third film to feature Gosling and Stone as lovers, following Crazy, Stupid, Love and Gangster Squad.
Emma Watson turned down the role of Mia due to scheduling conflicts with Beauty and the Beast (2017), while Ryan Gosling turned down the role of the Beast in that film to appear in this film, coincidentally both are musicals.
The film was shot in eight weeks over the course of summer 2015.
According to composer Justin Hurwitz all of piano featured in the film was first recorded by pianist Randy Kerber during pre-production.
Ryan Gosling then spent two hours a day, six days a week in piano lessons learning the music by heart. By the time filming had begun, Gosling was able to play all of the piano sequences seen in the film without the use of a hand double or CGI.
