Los Angeles Mayor Eric Garcetti declared Tuesday "La La Land'' day before a group of acrobatic dancers gave a stunning performance suspended by ropes along the side of City Hall as a jazz ensemble played several tunes from the film.
Garcetti even showed off some of his own jazz stylings and played the piano for the crowd.
The film's Oscar-winning director, Damien Chazelle, composer Justin Hurwitz and production designers David and Sandy Wasco were on hand, along with choreographer Mandy Moore and jewelry designer Kyle Chan.
The modern musical stars Ryan Gosling and Emma Stone as two Hollywood nobodies who fall in love while trying to make their dreams come true. The film prominently features many L.A. locales, including the Griffith Park Observatory, the Angels Flight railway and the Grand Central Market.
"In 'La La Land' we saw, as it has been stated so often, a beautiful, beautiful postcard to the city,'' Garcetti said.
The film received six Oscars at the 89th Academy Awards, including best director, original score and production design, but also famously had the best picture trophy taken away after being mistakenly declared the winner instead of "Moonlight."
NBC4 reached out to Lionsgate and the mayor’s office, and both say all the funds to throw the celebration came from Lionsgate and no city funds were spent.
