Sidney Lumet sobre filmar:

There's no right or wrong way to direct a movie. What I'm writing about is how I work. For students, take it all; take what you want and throw the rest away; or throw it all away. For a few readers, perhaps it might make up for the times a movie crew has tied you up in traffic, or shot in your neighborhood all night long. We really do know what we're doing: It only looks as if we don't. Serious work is going on even when it seems as if we're just standing around. For everyone else, I'll try to tell you as best I can how movies are made. It's a complex technical and emotional process. It's art. It's commerce. It's heartbreaking and it's fun. It's a great way to live.
