A Patch of Blue is a 1965 drama film about the relationship between an educated black man and an illiterate, blind, white 18-year-old girl against the backdrop of the growing civil rights movement. It stars Sidney Poitier, Shelley Winters, and Elizabeth Hartman. This was Hartman's first film. She retired from film in 1982. Having suffered from depression for most of her life and after years of treatment, she killed herself by jumping from her 5th floor apartment building. She died on June 10th, 1987, at the age of 43. I watched this movie on HBO Max.
Variety describes it as "a touching contemporary melodrama, relieved at times by generally effective humor" and describes Hartman's debut performance as "exceptional". Rotten Tomatoes has a critics consensus score of 89% and an audience score even higher.
