About as reliable as one could ever find, character actress Mary Treen was a familiar face to most and could always be counted on to bring a bit of levity to any film scene. A minor actress for much of her career, she managed to secure a plain, unassuming niche for herself in 40s, 50s and 60s Hollywood. She was born Mary Louise Treen in St. Louis, Missouri in 1907, her father dying while she was still an infant. Raised in California by her mother, who once performed under the stage name Helene Sullivan, and her stepfather, a physician, she attended the Westlake School for Girls as well as a convent where she tried out successfully in school plays.
海蒂·麦克丹尼尔斯是奥斯卡历史上第一位黑人获奖演员，在此之前虽然黑人演员众多，但甚至连被提名的都没有。而其貌不扬的哈蒂能够荣膺此艳，不可不说是她演技超群所致。
