Universal was concerned about the controversial nature of "Nuts" and eventually sold it to Warner Bros., where it remained in limbo until 1986, when Streisand was signed for $5 million plus a percentage of the gross. Topor and Rydell clashed about the film's focus and Rydell eventually quit, citing scheduling problems, budgetary concerns, and artistic differences. It was his second time that he had abandoned a Streisand property; he had walked away from "A Star Is Born" a decade earlier. Streisand assumed producing duties but declined to direct, and Martin Ritt was hired to replace Rydell. Streisand hired Andrzej Bartkowiak, who had filmed the documentary chronicling the making of "The Broadway Album", as director of photography. She researched her role by studying schizophrenic patients in a mental ward and interviewing prostitutes at a Los Angeles brothel, and began to work on her own draft of the screenplay. Although she received no screen credit for her work, the studio later publicly acknowledged her contribution.
