Nice clip from Searching For Bobby Fischer. Though Ben Kingsley has most the lines, I like how the focus in on the boy. When animating to dialogue, we often just cut to whoever is speaking. Instead of doing this, you should make sure the camera is cutting to what's most important, regardless of who is talking. In this scene for instance, the most important thing is showing the boy struggling, trying to figure out this test. So instead of cutting to the speaker, they kept the focus on him. This movie was shot by the late great Conrad Hall, who in my opinion is the greatest cinematographer ever.
