Most of the extras and supporting parts were played by non-professional actors that Andy Milligan met on the streets around Staten Island and recruited them to appear unpaid and uncredited. The two players who played the parts of the court potentates, dubbed Peter the Ear and Peter the Nose, were two brothers who owned a local hardware store and were rumored to have had Mafia connections.
Most of the exterior scenes set up to resemble England were filmed at the Mt. Loretto Unique Area in southern Staten Island.
