Director Howard Hawks To Have and Have Not marks the first screen appearance of Lauren Bacall; the first of 4 with her future husband, Humphrey Bogart.
Bacall's smouldering "Look" was crafted here and the on screen chemistry with Bogie is palpable from their first encounter.
The film features arguably Bacall's most famous line;"You know how to whistle, don't you, Steve? You just put your lips together and... blow."
