Keaton served as the muse for America's favorite hypochondriac auteur Woody Allen, notably starring in his masterpiece, 'Annie Hall'. The heroine was based not-so-loosely on Keaton ("Annie" is a nickname of hers, and "Hall" is her original surname). Supposedly she entered in 'Annie Hall' garb and when the costumer tried to dress her for filming Allen said 'Leave her. She's a genius. Let's just leave her alone, let her wear what she wants.'
