Betty Joan Perske was raised by her mother who pushed her to study dance and comedy. To financially support herself and her family, she starred in a few Broadway pieces while earning a modelling contract. In 1943, Diana Vreeland puts the young woman on the cover of Harper's Bazaar and she is remarked by Howard Hawks' wife who suggests Lauren Bacall for his upcoming film, To have and Have not alongside Humphrey Bogart who will become her husband. Shy and hiding behind her iconic hairstyle, the actress stares at people from under which gives her a seductive air and the nickname, 'The Look'. From then, the American actress has never stopped acting, even risking herself in Lars Von Trier's unusual world. However, she remains legendary Slim who once told 'Bogie': 'You know you don't have to act with me, Steve. You don't have to say anything, and you don't have to do anything. Not a thing. Oh, maybe just whistle. You know how to whistle, don't you, Steve? You just put your lips together and... blow.'
