Roger Ebert, in his review of 12 Angry Men, an early film of the late Sidney Lumet
The visual strategy of the movie is discussed by Lumet in Making Movies, one of the most intelligent and informative books ever written about the cinema. In planning the movie, he says, a “lens plot” occurred to him: To make the room seem smaller as the story continued, he gradually changed to lenses of longer focal lengths, so that the backgrounds seemed to close in on the characters.
“In addition,” he writes, “I shot the first third of the movie above eye level, shot the second third at eye level and the last third from below eye level. In that way, toward the end the ceiling began to appear. Not only were the walls closing in, the ceiling was as well. The sense of increasing claustrophobia did a lot to raise the tension of the last part of the movie.” In the film’s last shot, he observes, he used a wide-angle lens “to let us finally breathe.”
