Interestingly enough, most of the gangs portrayed in the film were neither symbolic nor imaginary, but were based on various real gangs who existed at different periods throughout the fifties and early sixties.
Many of these gangs were not real gangs in the common theatrical sense, but were specific ethnic groups of teens from different Bronx and Manhattan neighborhoods. Of course, each group developed its own mythical idea of what the other groups were like, and in his novel, Richard Price used much of this teenage myth and lore.
Of all the well-embellished epics common to the teens in the Wanderers' neighborhood , those dealing with the Duckies were the most detailed and commonly accepted. The Duckies, whether or not they were truly an organized group with such a name, were "the guys across the tracks", insofar as The Wanderers were concerned (the tracks being the NY Central's Harlem Line). They lived in the predominantly Irish neighborhood directly across Bronx Park. I believe their frightening, near demonic quality in the movie was based on a single actual event when two of the Wanderers were actually attacked in the park. Since The Wanderers had never really engaged in any real "gang wars" (or any significant fighting for that matter), that particular episode was the source of most of their perceptions of the Duckie Boys' penchant for unbridled violence.
