Bobby in the act of picking up a drug shipment. In the next two weeks, Hotch approaches Helen several times, reminding her of her pending trial. Depressed, she increases her drug use, but finally agrees to help the police. One night Helen and Hotch watch a squad of policemen apprehend Bobby, who is in possession of a large amount of heroin. When Bobby spots Helen on the street, he yells at her. Months later, when he is released from jail, Helen waits for him at the gate. Although his first impulse is to rebuff her, he turns to her and asks her, "Well?", and together they walk away. Cast Production The film was based on a novel by James Mills, which had been based on Mills's two-part pictorial essay in the 26 February and March 5, 1965 issues of Life magazine. According to a November 1967 Hollywood Reporter news item, film rights for the novel were purchased by Avco Embassy Pictures and, according to a March 1969 Variety news item, the film rights were later bought by producer Dominick Dunne, whose brother and sister-in-law, John Gregory Dunne and Joan Didion wrote the screenplay. As noted in the onscreen credits, the film was shot entirely in New York City. According to the film's studio production notes, portions were shot at Needle Park and the Upper West Side area of New York City, at Riverside Park, in a New York City prison and hospital ward, on the Staten Island Ferry, and in the East Village. The studio notes reported that makeup man Herman Buchman studied the "track" marks on the arms of hospital patients and victims in morgues and achieved an authentic look for the actors by using a liquid called Flexible Collodion. In scenes in which actors appear to inject themselves, a registered nurse was on set, serving as a technical advisor. Ned Rorem was to compose the film's score until it was decided that no music would be used (his isolated and unused score is included as a special feature in the Blu-ray). Much of the film features cinéma vérité-style footage. It is believed to be the first mainstream film to feature actual drug injection. Didion and Dunne visited Jim Morrison, lead singer of The Doors, during the recording of the album Waiting For The Sun as he was considered for the role of Bobby, but went with Pacino instead.
