It used to be believed, that this short documentary was released in 1965, but this was incorrect: The end credits include a copyright date of 1969. In the documentary one of the lawyers also makes a reference to the riots of Newark, New Jersey, which took place in 1967, therefore the shoot must have taken place after that event.
For years, books about De Palma had listed this short documentary as a film titled "Bridge That Gap", which was incorrect.
