Hitchcock

Invisible Ink mentioned Hitchcock's "pure cinema" idea, which googled me over to http://www.borgus.com/think/hitch.htm with some interesting ideas

Emotion comes directly from the actor's eyes. You can control the intensity of that emotion by placing the camera close or far away from those eyes. A close-up will fill the screen with emotion, and pulling away to a wide angle shot will dissipate that emotion.

before audio, silent film camera's wandered around examining the scene, showing the audience props that were important to the story. Once talkies came they stopped and relied on the dialogue.

Putting an idea into the mind of the character without explaining it in dialogue is done by using a point-of-view shot sequence. This is subjective cinema.
- Start with a close-up of the actor
- Cut to a shot of what they're seeing
- Cut back to the actor to see his reaction

Information" is essential to Hitchcock suspense; showing the audience what the characters don’t see. If something is about to harm the characters, show it at beginning of the scene and let the scene play out as normal, it will be much more entrancing because the audience wants to warn the characters.
