I Never Promised You a Rose Garden is a 1977 film based on the Joanne Greenberg novel of the same name.
In the wake of the success of One Flew Over the Cuckoos Nest, Roger Corman was able to get funding for a movie version of Rose Garden. Bibi Andersson played Dr. Fried, while Kathleen Quinlan played Deborah. All references to Judaism were removed, including the storyline of the vicious cruelty Deborah suffered from antiSemitic peers, so that her childhood bout with urethral cancer becomes the sole reason for Deborahs retreat from reality.In an interview, Greenberg stated that the references to Judaism were removed because the producers were terrified. The author added that the characterizations of mental illness in the film stank on ice. ........
