The character Teddy Wong, the head of the Asian gang, was no doubt a shout-out to "The Wanderers" (1979) movie's character Teddy Wong, who was the head of a gang called The Wongs (every member had the last name Wong).
Bobby Cannavale and Max Casella previously worked together on the television show "Vinyl" (2016).
The website Movie Insider incorrectly credits this movie by its working title "Once Upon a Time in Staten Island," even after the movie was released in 2021.
