In the opening credits, filmed on Stone St. in Tucson, AZ, the Pioneer Hotel is briefly visible, and farther down the street, Steinfield's Department Store. The hotel was said to be "100 percent fireproof", a claim that was refuted in December 1970 when fire swept through the upper floors, claiming 29 victims - among whom were Harry and Margaret Steinfield, who lived in its penthouse. The building was repaired and is now a mixed-use apartment and office space.
Arthur Kennedy would say later about Nicholas Ray that he had a most peculiar way to direct actors. Kennedy agreed on everything that Ray told him but never figured out what he meant.
Bull ropes used during the era when the film was shot were created from strands of braided grass. These days, ropes are made from strands of braided polyester and the handles are reinforced with stiff leather to help prevent rider hang-ups.
