Mamet essentially perceives directing a film as an emotionless process. He believes that we gain the best understanding and enjoyment of a story through the juxtaposition of uninflected images and uninflected acting, which is very low in emotion. While I have a preference for films that offer subtle suggestions of particular emotions, Mamet contends that anything more than the subtle portrayal of emotion or the simple repetition of behaviors to convey personality is excessive. He argues that explicit moments of emotion will only serve to distract the audience. In my view, a balance between both is essential for creating a good film.
Mamet also employs annoyingly pretentious language, using odd and rather alarming metaphors. For instance, he states, "As Leadbelly says about the blues, he says in the first verse use a knife to cut bread, and in the second verse use a knife to shave, and in the third verse use it to kill your unfaithful girlfriend." I understand the point Mamet is trying to make, but seriously, what on earth? For someone who emphasizes careful planning in presenting a point, choosing this violently misogynist metaphor as the best and most necessary way seems rather inappropriate. Not to mention that he consistently refers to every example character as "he" and provides examples of desires like "wants to sleep with the girl," as if main characters can only be straight men. I would recommend this book to anyone interested in directing film, but it should be read with a very critical eye! (As one should approach all sources, anyway.)
