Mrs. Harris (2005)

Fact-based story about Jean Harris (Annette Bening), a woman who was accused of murdering famed Scarsdale Diet Dr. Herman (Hi) Tarnower (Ben Kingsley) after being in a relationship with him for 14 years. Depicted as a womanizer, Dr. Tarnower had earlier asked Mrs. Harris, a divorced school teacher, to marry him. But when faced with upcoming nuptials, he backed out. The story depicts Mrs. Harris as a distraught and obsessive woman who may have been suffering from some mental illness and based on a note sent to the doctor, may have been suicidal at the time of the murder. She contended that Dr. Tarnower was shot while the two wrestled with a gun she was going to use to kill herself. Contains profanity and sexual situations, including implied masturbation. (from IMDB).
