It isn’t the opening dance number on a jammed Los Angeles freeway interchange, or the surreal extended homage to “The Band Wagon” and “Singin’ in the Rain.”
But then "La La Land" isn't trying to be "The Band Wagon."
At the climax, Chazelle pulls it all together with a what-if musical fantasy evoking visual and conceptual aspects of the "American in Paris" ballet, the "Girl Hunt" sequence from another, even greater Minnelli film, "The Band Wagon," the "Broadway Ballet" from "Singin' in the Rain" and more.
One sequence, which is shot in an extended, one-shot take overlooking the city of Los Angeles, has a similar budding romantic vibe as Fred Astaire and Cyd Charisse‘s Central Park dance in The Band Wagon .
He makes allusions to Singin' in the Rain (1952), The Band Wagon (1953), Funny Face (1957), The Umbrellas of Cherbourg (1964), The Young Girls of Rochefort (1967), and more.
The climax is like one of those long ballet sequences in Minnelli's An American in Paris or The Band Wagon, beautiful, and imagining what life might have been like if the lovers had done everything correctly, but then it ends on a more Demy-like note, bittersweet.
