Production
The first draft of the film was under the title Bring on the Dancing Girls. Scorsese shot footage in Little Italy of J.R. and his friends participating in "fights, drinking sessions, orgies", but Scorsese stated that it was "a disaster and everybody hated it". Haig P. Manoogian, his former professor, told him to write new scenes featuring the girl and expand upon J.R. inner conflict. Who's That Knocking at My Door was filmed in New York City over the course of two years, undergoing many changes, new directions and different names along the way.
