70 Acres in Chicago: Cabrini Green is a video and study-guide documenting a key point in Chicago's housing history when high-rise public housing was torn down and replaced with low-density, mixed-income communities. The film provides a salient historical context and political analysis explaining the birth of Chicago's public housing and why it is currently slated for demolition, while exploring the impact of this demolition on the Cabrini community. The film examines key questions of identity: How does physical environment play in role in shaping our identities? What happens to our collective identities when the physical community is destroyed? Cabrini Green is a sequel to Bezalel's critically acclaimed Voices of Cabrini: Remaking Chicago's Public Housing (1999), a documentary chronicling the redevelopment of Cabrini Green from the perspective of residents, community activists, and local business owners that was described by Newsweek as a "touchstone in the debate over public housing."
