'To Have And Have Not'
In 1944, Lauren Bacall was discovered by Director Howard Hawks wife from a model photo on the cover of Harper's Bazaar. When Hawks saw Bacall, he found her and cast her right away, opposite Humphrey Bogart.
Bacall and Bogart began a romance almost immediately, despite Bogart being married to actress Mayo Methot, his third wife. Hawks disapproved of the affair because of the negative press he feared it would generate.
The budding romance would soon lead to Bacall and Bogart getting married a year later.
In To Have And Have Not, Bacall delivered one of her most famous lines, "You know how to whistle, don't you, Steve? You just put your lips together and... blow." It became one of the most famous cinematic lines ever.
