The graffiti highlighted throughout the film was actually painted by set artists not real graffiti artists. Graffiti consultants to the film were Bill 'Blast' Cordero (who worked on Studio 54's Graffiti party) and Phase II Lonny Wood. Phase II went to De Witt Clinton High School in the Bronx and was one of the first graffiti artists to gain exposure & notoriety in NYC for his work on subway trains. He was also an African American graffiti artist, whereas, like Ramon, a large number of the early graffiti artists from the Bronx were Puerto Rican. With credentials like that it begs the question why they weren't asked to do the artwork themselves.
Ramon's character was actually based on a real life graffiti artist 'Seen' who was featured in the PBS documentary on all things hip hop in the Bronx 'Style Wars'.
Most, if not all, of the empty lots shown in the South Bronx in the movie are now 1 and 2 bed family homes. The lots no longer exist. The church that was shown in Ramon's building, when his Dad screamed at him from the window is still there. The name has changed, but the church is still there!
When movies are made, scenes are often
left on the cutting room floor.
The Roadshow Trailer contains other deleted scenes from The main Trailer (which also contains rare footage). There's extra bits from the Famous Roxy Battle as well as different camera angles.
Sometimes, there will be several versions
of a movie floating about on cable, tv or video etc. Other times, a Director may
release a special cut of the movie.
