The first major film about psychiatry, Private Worlds stars
Claudette Colbert as a psychiatrist with more than a few problems of her own. Colbert's appointment to a top mental hospital is frowned upon by head doctor
Charles Boyer, who doesn't have much confidence in woman doctors of any kind. A secondary storyline involves Boyer's sister
Helen Vinson, who lusts for a young married doctor (
Joel McCrea). The doctor's wife (
Joan Bennett) subsequently goes insane in an "off-angled" scene anticipating the techniques of
film noir by nearly a decade. Meanwhile, doctors Boyer and Colbert establish a mutual respect which deepens into love. Based on a novel by Phyllis Bottomes, Private Worlds is stronger in its vignettes (including a scene in which Boyer comforts a dying patient by speaking a few words in the patient's native tongue) than in its longer "plot" scenes. ~ Hal Erickson, All Movie Guide
