“Films nowadays are full of dialogue, but it shouldn’t be explanatory. So I begin by imagining how to express the story as a silent film.
“…The viewer should engage their imagination as they watch a film with the filmmaker’s imagination. But with all the colors and sounds in a film, everything tends to get overly explained. The worst offense is when dialogue becomes explanatory…although that may make a film easier to understand. Rather than expressing, film has evolved towards describing.”
From the documentary Akira Kurosawa: It Is Wonderful to Create, included on the Criterion DVD of Kurosawa’s Drunken Angel (1948).
