According to David Mamet, a film director must, above all things, think visually. Most of this instructive and funny book is written in dialogue form and based on film classes Mamet taught at Columbia University. He encourages his students to tell their stories not with words, but through the juxtaposition of uninflected images. The best films, Mamet argues, are composed of simple shots. The great filmmaker understands that the burden of cinematic storytelling lies less in the individual shot than in the collective meaning that shots convey when they are edited together. Mamet borrows many of his ideas about directing, writing, and acting from Russian masters such as Konstantin Stanislavsky, Sergei M. Eisenstein, and Vsevelod Pudovkin, but he presents his material in so delightful and lively a fashion that he revitalizes it for the contemporary reader.
