Andy Garcia's character can be heard yelling the name "Manny" when addressing the stunt coordinator on the set of the film within a film; in the real film (City Island), Manny Siverio is the Stunt Coordinator.
It's interesting to find out that the exteriors, including the final climactic scene, of this movie were actually filmed on City Island, Bronx. If you look up City Island on Google Maps and zoom in to 1 Horton Street on "street view" you'll see the house that served as the exterior shots in the movie. Though the house across the street where the "Botero" lady lives is completely different.
