** Much like how the first film was heavily inspired by ''Film/TaxiDriver'' and ''Film/TheKingOfComedy'', this film takes influence from another Creator/MartinScorsese film, ''Film/NewYorkNewYork''. Some of the musical sequences are also shot in a way that's meant to evoke ''Film/LaLaLand'', another GenreThrowback to Golden Age-era musicals.
