Most of the graffiti art that was displayed all throughout the film was not done by real graffiti artists - it was airbrushed by set decorators, however, two grafitti artists were hired as creative consultants for the film, including Bill Cordero - aka "Blast", and Lonny Wood - aka "Phase II", (who is also referenced in the movie, during the subway graffiti scene)
About 80% of the footage in the original theatrical trailer is not included in the final cut. Examples include Ramo getting his bag ripped off while walking with Kenny and Charlie, several battle outtakes including the classroom up-rocking scene, Ramo on a set of drums, and one dancer flipping off against a wall at the Burning Spear nightclub. Several other pieces of footage were included as well but were in freeze frame in the opening credits of the film. The trailer also includes an alternate version of title song performed by Kool Moe Dee, (who appears in the film in the "Christmas Rappin'" sequence with the rest of the Treacherous Three), which also did not appear in the movie nor on the original soundtrack albums.
This project was sponsored by Puma. The original soundtrack LPs have the Puma logo printed on them, reading, "Puma as seen in 'Beat Street.'"
It was the producers' idea for the main cast to wear Kangol hats and Puma sneakers all throughout production of the film even though many of the dancers felt that it wasn't authentic.
According to Fast Break (who appeared in the Treacherous Three sequence), there was a classroom up-rocking battle scene that involved the New York City Breakers and the Rock Steady Crew, but it was cut. There was also more of the climatic battle between these two crews at the Roxy nightclub.
