The film was shot on a budget of around $250,000 filmed entirely on location, and many of the supporting cast members were friends and family of the filmmakers. It was filmed in the Pittsburgh suburb of Braddock, Pennsylvania during the summer of 1976. Producer Rubinstein acknowledges that where he indicated a budget of $250,000, the actual budget was only $100,000, but he did not want anyone thinking that they could just commission a film for $100,000, so he inflated the figure to what he estimated would be a reasonable, independent budgeted amount.
