Lauren Bacall for "To Have and Have Not" (1944), Bacall was so nervous that, to minimize her quivering, she pressed her chin against her chest, faced the camera, and tilted her eyes upward. This effect, which came to be known as "The Look", became another Bacall trademark, along with her sultry voice. Bacall's character in the film used Slim Hawks' nickname "Slim", and Bogart used Howard Hawks' nickname "Steve". The on-set chemistry between the two was immediate according to Bacall. She and Bogart (who was married at the time to Mayo Methot) began a romantic relationship several weeks into shooting. Bacall's role
