Diamond in the Rust is a documentary that examines decades of failed urban planning and redevelopment in Willets Point, Queens, an industrial enclave known as the Iron Triangle. Through archival footage and interviews with residents, workers, journalists, and policymakers, the film traces how repeated promises of affordable housing and community investment were sidelined in favor of speculative projects that stalled or collapsed. As New York Mets owner Steve Cohen proposes a massive casino and entertainment complex adjacent to Citi Field, the film interrogates whether this latest plan represents genuine progress or another reshaping of the neighborhood around elite interests. At its core, Diamond in the Rust asks what a truly successful outcome for Willets Point would look like and who gets to define success after decades of neglect, displacement, and broken trust.
