The neighborhood where the film takes place is the same street where the film's director, F. Gary Gray, grew up in South Central, Los Angeles. Principal houses that were used for filming were houses of old friends of the director. The scene where Deebo punches Red into the air is the house that F. Gary Gray grew up in.
In the flashback scene where Smokey is in the car with Hector and his friend, two men can be seen sitting on a block wall in the background. The men were residents of the neighborhood who wanted to be difficult towards the production staff, knowing they couldn't tell them what to do on their property. They remained in the shot despite offers from the staff which included compensation or a walk-on role in the film.
