The White Unicorn would be worth watching if only for that lyrical title. The film itself, however, isn't quite so whimsical, not with disgruntled widow Lucy (Margaret Lockwood) and hard-bitten unwed mother Lottie (Joan Greenwood) at the forefront. Trying to find a purpose in life, Lucy takes a job as warden at a home for wayward girls. She tries to bring comfort to Lottie, who faces a stiff prison sentence for attempting to murder her baby. As the two women compare their life stories, they realize that they're truly sisters under the skin. A "woman's picture" if ever there was one, White Unicorn also affords its male actors (Ian Hunter, Dennis Price, Guy Middleton et. al.) ample opportunity to reach new dramatic heights. Featured in the cast as Lucy's daughter Norey is Margaret Lockwood's real-life daughter Margaret Julia.
