La Promesse

La Promesse is a movie filled with emotions of stress, anguish, turmoil, and rebellion. And we get to feel and see all of that through the experiences of Igor, a 15-year child whose father exploit undocumented immigrants in Belgium. When one of these immigrants dies and Igor's father covers up the death, Igor is caught between being a loyal son or keeping his promise to the dying to help his family. This struggle and all of the following emotion is captured almost exclusively through the use of close-ups. In the article I read, it explains that close-ups are especially good at this. By zooming on the face, we are able to better see the features of the actor: mouth and eyes in particular, as he reacts to the action unfold. A facial twitch, a tear, or dart of the eyes that might have been lost to the audience with a wide shot is perfectly captured in a close-up.  As the article points out, one of the best examples of this is the scene in The Shining when Johnny breaks down the door. The scene would be completely different, with much less terror, without its iconic close up.
